Bigger Injectors Stock Ecu





Or you can just switch your untouched stock ECU for dealership visits (if you order pretuned ECU). These injectors will also be a direct fit for a twin cam RB30 built with a an RB26 head and intake. I don't see the need to pay for something that's overkill which bigger injectors are on an otherwise stock engine. - Feedbacks As of today 03/07/2018, we've done little over 6000+ Genesis coupes ECU flash and custom tunes (both 2. When using stock fuel injectors this table does not need to be altered. Therefore you should plan your injectors being 35-40% larger than if you were going to run gasoline. I believe 550cc is the biggest you will need on a stock ECU if you get a bigger ECU like AEM or MegaSquirt you can go bigger after that. i will use 100octane fuel. Turn around time: 1-2 days from receipt. Does not appear a problem at the moment but I want to be safe and in future the performance mods i will do will probably require bigger injectors anyhow so its an idea. for that power a reflashed NISTUNE ECU is ideal. Load sensor adjustment is frequently used to compensate for larger injectors. i was thinking of finding injectors that flow 10% more on an old used car so we can have a junkyard $100 major upgrade that will likely beat ecu upgrades btw anything over 10% bigger is the max you should have on a stock ecu too much gas is bad python sells stock injectors rebuilt to flow 10% more but these are seriously pricey. but like the others have said some bigger injectors atleast the 550cc but for an extra $10 you might as well get the 740cc ones incase you want to go more power down the road. In preparation for my supercharger install, the install of 75 lb/hr injectors, and the ECM limit of 63. 5cc under normal load and 178. That said, the ECU can not adjust for such a large increase in fuel flow. i kinda wanted to sell the 550's and get 370's but idk where to get them. Rad,cool bypass, kooks headers and t/d's with cats on the way,and 3. Any changes to this table will affect ALL tables within the ECU related to fuel delivery calculations. The stock injectors are 24 lb/hr at the stock pressure of 55 psi. A shitty chip will do that, but really sketch to run injectors past 90% (85% is a better limit). For example if the stock K value is 34,275 and injector size was changed from 370cc to 550cc then the new value will be 21,475 x (370/550) = 14,447. I since went bigger for bigger turbo. So if you put in larger injectors they will inject more fuel for the same "on" time, and the stock ECU will provide the same "on" time as before, not knowing the injectors are a different size. The car is pretty much stock ATM all it has is the SS induction and soon to be put on an SS throttle body. The fuel map has been increased by about 40% from 6000rpm to 14,000rpm at 100%tps. The Holley EFI Injector Driver Module will have you in complete control of your fuel injected behemoth, featuring easily programmable injector current curves, injector test fire mode, two datalogger outputs, multiple peak. This is used primarily for built N/A or boosted applications 1. 62ms dead time in account the actual opening times would be 1. High-resolution 486 point table allows fine tuning of performance and driveability. Once the engine gets to about 400 rpm the ECU will stop using this map and switch over to regular pulse width calculations. The injectors are Accel 30lb High Impedance from a LT-1. If you want to run larger injectors with the stock fuel system you have to modify the signal from the MAF sensor to compensate. That'll probably be a good choice. i dont think he wants to turbo the car i think he was askin about just boosting the hp a little with injectors. These injectors will also be a direct fit for a twin cam RB30 built with a an RB26 head and intake. The engine is fully built, has a decent size blower on it, and larger injectors. Drain the tank, fill with E85 and pop in these injectors. ) Program for MAFless operation = speed density mode. Even with just the 450's I'm looking at $728 for the set w/adapters. 6L 4A-FE with larger injectors. Furthermore, the OEM ECU will not be able to handle an injector that is more than 20% larger than stock and will suspect that one or more of its sensors are faulty and will revert to its programmed settings, which means that the fuel air mixture will not be optimal and will probably be rich as this is the failsafe setting on the ECU when it. Eventually I'll add my Quarterhorse and A9L with 47lb injectors and E85 into the equation but not until my tired old motor gets a rebuild. Engine aspiration, {Turbocharged, Supercharged, and Naturally Aspirated engines have different BSFC’s (see Glossary of Terms for definitions)} Desired horsepower, (The amount of power you. Now we need to divide the total fuel requirement by the number of injectors being used. 3 lb/h divided by 80 lb/h (both at 3 bar) gives 0. The engine h22(a) type-s red top, the harness obd1 civic ex, obd1 injector clips, ECU P28 obd1 (stock) got my car back from the shop with d1. c) it is not necessary to retune the ecu, unlike injectors. At the very least an ECU reprogram will be absolutely necessary. Warren Diesel themselves are selling stock remans for $2050/set. 3 Capri, Turbo 2. Installing bigger (higher flow) fuel injectors to your stock engine is not advised unless other changes to your fuel system and/or re-mapping of the ECU is also done. If you have 440cc, then no larger than 880cc, assuming you are not talking about pump gas, not E85. 5 psi at idle). And Stages 2inj (inj being short for injector) through Stage 5inj require larger fuel injectors which are included with your tune. Correction factor is only -30%. They will be fine unless you are pulling more than 260rwhp if they are still in good condition. First, some background information on how the Subaru ECU controls Air-to-Fuel Ratio at low load (idle, low throttle, cruising) where AFR is kept at ~14. His name is John Schaefer and works at Cobb now. i wont be uninstalling the kit and installing it into my car the same day, and ill probably need to drive the car around (minimally if need be) for a couple weeks before putting the kit on. In the end your air fuel ratio at any given RPM/load is set by the map/tune on the ECU. The car is pretty much stock ATM all it has is the SS induction and soon to be put on an SS throttle body. To work with the fuel pocket on the piston. ill be using the standard ecu, im thinkin now of just using a rising rate reg and bigger pump of course for up to 3psi and then once its all tuned right for that, two extra injectors 36lb+ each positioned after the compressor to supply the extra fuel at top, for a ~7psi setup. On a stock ECU you will be lucky if the car runs at all with those injectors. To my knowledge it (particularly the Delco) doesn't have a way to measure fuel rates, they're set by the tuner. Stock 2003 injectors are 527cc, 2004-2005 injectors are 577cc. 0 ecu are remarkable similar, as are the maps within them. I'm running mine on untuned stock ecu setup, i have added an emanage blue (~$250) - but this was to compensate for running bigger injectors, i've not actually modified the tune if that makes sense, just auto corrected for injector size. It would work like a champ. From personal experience, with 550cc/min injectors and a 3-bar MAP, my car idles just like stock. just putting bigger injectors wont boost hp and even if you wanted to you need a ecu upgrade to do that. i been driving for like a year lol i know its bad but its my only car right now and i just paid 160 for a stock fuel injector :-( im putitng it in monday and how do i get a reflash to stock ecu i dont have accessport or anything. Can I fit bigger injectors that are around 450cc or 500cc? Im not ready for a new ecu and tune yet. Save Share. It's not as easy as just slapping a bigger set of injectors in and running E85. If your dropping in bigger injectors you will probaly need a new adjustable FPR and fuel pump. We have found Honda ECUs work particularly well with larger injectors. The fuel map has been increased by about 40% from 6000rpm to 14,000rpm at 100%tps. According to your informations, no modifications should be done to my ECU for ACC-150826 injectors. Install this turbo kit and boost to 9PSI on stock internals, headgasket and injectors. This is because the ECU controls the duration of the opening and closing of the injectors; if the stock ECU is used, it will flood the engine with fuel. Any changes to this table will affect ALL tables within the ECU related to fuel delivery calculations. FI late model GM engine, still stock and on stock ecu (-> HPTuners). In most other cases the injection duration of that bigger injector will be shortened to get the lambada value at the desired level. All EFI-equipped models. Different strokes for different folks. Therefore, when the driver transistor turns on, there is an additional 0. Lambda is lambda, regardless of fuel. Re: Best Injectors to use with stock MSM ECU ? « Reply #5 on: December 01, 2014, 06:25:30 PM » Speaking as one who has done it the bigger injectors work a little nicer and will allow you to turn up the boost to 10 psi while still maintaining good AF readings. So for $1450 it is obvious they are either modifying your old injectors or some taken as cores from somebody else. Ryan Dudek _____ Yes. The size of the injectors is a large contributor as to what this map looks like. I highly recommend at least reducing the values in this table if you are installing larger injectors. To build the most efficient fuel delivery system you may want to consider a piggy-back fuel computer and air/fuel ratio gauge. (looks like the car just has some small mods on it, none belive to be engine related) Question #1 - How can I tell if thease are the smaller '03 injectors? Question #2 - Can I buy the 04-05 bigger injectors and use them without re-programing the ECU? Thankyou in advance, Jesse. The oem injectors are designed to work with the airflow tumble and swirl in the cylinder head. 05 cc/min) at 5 bar. Cold air intake,long tube headers , catless pacesetter exhaust,msd coil pack and wires, step colder spark plugs , 15% sc pulley, light weight crank , upgraded fuel pump, larger intercooler. 6 turbo into my 82 Mitsi starion 2L all i did was, increase the size of the bypass port in the airflow meter, so the same amount of air goes through the sensor, the extra air goes around the sensor ,then added a variable resister to the computers water temp sensor, that retarded the spark, increased the. It's not as easy as just slapping a bigger set of injectors in and running E85. the fuel rate and curve can only correct itself so much. I'm looking to confirm that I'm on the right track when adjusting tables for larger injectors, I'm using Hobbit's most recent definitions and the 512kb full flash few_maps version and have a m54b25. When you go into open loop i see issues happening with bigger injectors and nothing to pull duty cycle. Pry off nozzle as carefully as possible. That said, it now has larger injectors versus stock, which means it will have to pulse them at a reduced duty cycle (i. Can somebody tell me what size the stock injectors are on a usdm H22A1? Also, does anybody know if the jdm H22A uses different size injectors? I have been trying to figure out why I am having problems when I run my usdm H22A1 on a jdm p13 ecu. With me just using an EWG, and tbe+intake(walbro too), my earlier tuner recommends to everybody going above a base stage2(tbe+intake) to use bigger injectors. Without this, your car would hesitate when you stepped on the gas. Will it run with the fmu? sure. 636cc for 720cc). I'm new to the fuel injection tuning. Turned timing back to center and hammered to 4. I have yet to detect any detonation, and the bigger injectors (I installed RC Engineering 320 cc/min Lucas style injectors) are easily keeping up with things so far. Anyone have any experience running this size or larger? I am thinking more of the idle department more than anything. Bigger Injectors/Fuel Pump on stock ecu OK? Jump to Latest Follow 1 - 4 of 4 Posts. but like the others have said some bigger injectors atleast the 550cc but for an extra $10 you might as well get the 740cc ones incase you want to go more power down the road. LB7 Bigger or Stock Injectors? Jump to Latest Follow 1 - 11 of 11 Posts. These injectors are enough to handle your typical bolt-on upgrades. The optimal flow of fuel is essential because the rich fuel mixture leads to power loss. Many ECU units are designed to ignore injectors that are 20% larger than the stock injector. ThanksJim August 6th, 2013, 17:28. The injectors will be for increasing fueling (mixture) if the ECU recognises its required at high revs WOT 5th and 6th. The bike runs super smooth now, especially at slower speeds, the rpms seem to climb a little faster (thus accelerates a little faster). That's cheap considering you'll have to pay a lot more for injectors and an AFPR with a big fuel pump. The ECM is what is "calibrated" for the injector size which is why these "calibrated" MAF trick the ECM into thinking it is the stock size for those injectors (by way of changing the sampling tube). 4 is already running lean id assume bigger injectors would fix that. The fuel calibration range supports conversion to larger injectors. One of the tricks that I discovered for fooling the stock ECU is to fit much larger injectors and tighten the tension on the AFM's spring. We found no option to perform as good as the OEM injector. - and what about the stock transmission i think its a A340E transmission if im correct, what's their limits and anything I should do about them. Adjusting the MAF rate is simply for smoke control. I am not getting a whole lot of help here. This allows you to fit larger injectors, larger Mass Airflow Meters and get your ECU tuned for these and fuel and ignition changes. 4 system is adaptive it will trim itself to compensate for the richer mixture it offer very little if any advantage. High-resolution 486 point table allows fine tuning of performance and driveability. According to Jeff Taylor the stock 370cc injectors can max out at 6 psi boost. as far as gains go they were decent from what i remember it was around 20hp or something like that plus 25 or so ft lbs. Guy is selling another. To build the most efficient fuel delivery system you may want to consider a piggy-back fuel computer and air/fuel ratio gauge. What you are doing is telling the PCM you have the equivalent of larger injectors that flow more, so they won't be pulsed as long (as the higher fuel pressure is a "replacement"). 5 = 150 LB/HR total fuel requirement. Besides there is a range of authority as to what the oxygen sensor can modify. The Apex'i Super-AFC is a good example of this type of device. If you add in a long term adaptive, that can go up to 50 or 60%. in your case a good fuel pump, raise fuel pressure about 30%, set injector balance to 50/50, and have a blast Use the ECU to progressively control the nitrous in each gear would work well. Normally ppl adding light turbo+tunning+larger injectors only added 30hp~40hp. Our socket service page page has details on how to check. For those serious about RX7 performance, looking for more power and more precise tuning we offer the Haltech stand alone ECU. You can't have bigger injectors and have no way of controlling them. 4 years ago i had tested the stock engine and I got 219 HP @ 5000 rpm (whp). No aftermarket piggyback unit does much more than modify the stock ECU injector pulsewidth pattern. 379; then sqrt(1. Yep hydrolock. I even briefly ran my stock NA ECU with the SC engine – just unplugged MS and plugged in the ECU. Keep in mind, none of these components "know" what the other is doing. DO NOT drive on 850s with a tune that thinks it is running stock injectors. Piggy-back A piggy-back system uses the factory ecu, but monitors certain engine parameters from the factory ecu and sends a modified injector or ignition output to achieve a desired. Here are two TBI injectors. On pre-2007 models the injectors are smaller than the Aero and 2007+ model year 1. Service includes before/after flow testing, ultrasonic cleaning, backflush, all new o-rings and internal filters. Hi Nick, Tanks for your post on Minitorque. The coil drivers have been eliminated from this version and Ignition outputs are logic level only. These injectors are enough to handle your typical bolt-on upgrades. Even adding fuel, what much can stock injector produce. Don't cheap out on EMS, that is where all the 'fun' is at, but I agree, ebay is making some solid stuff for cheap. I have been searching the forum and found this thread that did the same thing for the 5. Bigger injectors on their own will just increase fuel usage, make the engine run rich, which leads to running problems - it won't tickover, it won't pull cleanly through the rev range and you'll risk major damage through 'bore wash' - where the fu. If a 15% pulley is thrown into the mix that means the stock injectors will be running at about 92% duty cycle. Watch this 25 year old DSM lay down 230HP with 227lbs of torque. Pry off nozzle as carefully as possible. The injector sizes and dead times for each set of injectors do not need to be the same (e. You will want to set injector balance to 50/50 using ecueditor for big hp stuff on the stock injectors. It’s getting Ecmlink this upcoming week and bigger injectors. Would bigger injectors make any difference in performance, cause I thought that you only add them when the engine is starving for fuel. Eurodyne Maestro ECU Tuning Suite: Designed for those who want to take things further than the standard reflash, Maestro 7 allows a tuner to recalibrate for different hardware such as larger injectors, turbochargers and other performance modifications. Piggy-back A piggy-back system uses the factory ecu, but monitors certain engine parameters from the factory ecu and sends a modified injector or ignition output to achieve a desired. Without telling the ECU then injectors being controlled have a different flow rate, the ECU will not be able to properly control the pulsing of the injectors. Mitsubishi GTO J-spec TD05 EVO3 16G Turbo's. Lowering the RPM at which the secondary injectors come on allows them to add fuel before the primary injectors start to max out. The Fuel Injector Scale table contains is a singular value used to tell the ECU what is the size (or flow rate) of the fuel injector it is controlling. A good upgrade is the 24lb/hr injectors, which will support roughly 358 hp at the supplied 39psi fuel pressure. Neither ECU will be correct for 1. Which aftermarket ECU or piggy back system are you using? 650cc injectors are too large to run on the stock ECU without some sort of alternative ECU control, it will be running too rich so the MAF sensor will be seeing an abnormal voltage reading and then the MAP sensor will hit fuel cut. Ok probably a dumb question but can I run larger injectors on a stock turbo ECU? Matching impedance of course and specifically 420CC turbo supra injectors? I'm pretty sure I'll need to get nistune to run them, but I figured I would ask if it gets my swap done any quicker. You can expect a 100+HP increase from our Stage 1 kit. How does the FlashPro work with my FN2 GroupN ECU / FD2 Civic Type R ECU. Injectors have a duty cycle and you should not exceed 80%, if you do then you have to bigger injector. This car is demoing the turbos i will start selling which house a billet version of the k04 064 but has the fitment of. However the stock ECU limits the injectors duty cycle to around. 6 turbo into my 82 Mitsi starion 2L all i did was, increase the size of the bypass port in the airflow meter, so the same amount of air goes through the sensor, the extra air goes around the sensor ,then added a variable resister to the computers water temp sensor, that retarded the spark, increased the. The four most common systems and methods are piggy-back tuning systems, a modified stock engine control unit (ECU), flashing the stock ECU, or a standalone ECU. Correction factor is only -30%. You will want to set injector balance to 50/50 using ecueditor for big hp stuff on the stock injectors. You can't idle more than a 320 or so injector with the stock ECU. This is because the ECU controls the duration of the opening and closing of the injectors; if the stock ECU is used, it will flood the engine with fuel. Run the stock injector. I've never seen a reason to go with a smaller injector. 44 to get the injectors under the 60lb limit and keep everything in proportion. Many ECU units are designed to ignore injectors that are 20% larger than the stock injector. 5 psi at idle). When using stock injectors with Petrol fuel, this value DOES NOT need to be altered. 3L Powerstroke Injectors vary in price from $1,350. 75cc under WOT. So keep that in mind when deciding on your Injector Size Scaling. With the stock ECU, the only way to use slightly larger injectors (like 45's or something) is to have an adjustable fuel pressure regulator so you can lower the base fuel pressure to make the injectors flow close to 35 lb/hr so it's not running constantly rich (which is what it would do with 45's and stock fuel pressure). The engine control unit (ECU), fuel and O2 sensors, and the fuel pressure regulator are all working together to maintain the proper air-fuel ratio (AFR) for optimum engine. Better yet, the process isn't all that difficult, so that even a newcomer could figure it out. in your case a good fuel pump, raise fuel pressure about 30%, set injector balance to 50/50, and have a blast Use the ECU to progressively control the nitrous in each gear would work well. All EFI-equipped models. You can make bigger HP and run safer. GYTR turbo kit re-flash up to 350hp: This ecu flash allows you to run anywhere from stock boost to 18. so the correct formula is = 0. What issues will i have problems with? car: 00civic dx/ y7 to y8 mini me crower 2 n/a,springs+retainers intake,header,exhaust,60mm tb 10. 6 civic ex obd1. If, lets say, the ECU put out 2 volts on one injector, in which will open it all the way and spray its maximum, with an amount of 10ml for instance - this will be on the stock Injectors. Service includes before/after flow testing, ultrasonic cleaning, backflush, all new o-rings and internal filters. Mustang Stock Fuel Injector Size Chart. I have a 2006 f350 with 77k. 000km I would like to know which bigger nozzles can be used to get a little more power without adjusting the ECU. The four most common systems and methods are piggy-back tuning systems, a modified stock engine control unit (ECU), flashing the stock ECU, or a standalone ECU. 5# is a fuel pump upgrade and fuel pressure regulator with return line, and wastegate. You can expect a 100+HP increase from our Stage 1 kit. the stock ecu can accept 11-14 ohm injectors, for the 4-6 ohm injectors you would need an add on resistor box. Can somebody tell me what size the stock injectors are on a usdm H22A1? Also, does anybody know if the jdm H22A uses different size injectors? I have been trying to figure out why I am having problems when I run my usdm H22A1 on a jdm p13 ecu. 0 @ 124mph on 93oct - 10. This means at maximum duty cycle they will put out 260cc's of fuel in one minite. Then again the ECU may cause the leanness. I'm running mine on untuned stock ecu setup, i have added an emanage blue (~$250) - but this was to compensate for running bigger injectors, i've not actually modified the tune if that makes sense, just auto corrected for injector size. 7 V through a 6 ohm load resistor (Rload, a 5 W ceramic power resistor, bonded to the case of the ECU to act as a heat sink). Mitsubishi FTO Red lines: Completely Stock. so with the Z32 maf and AFC you could technically run even larger injectors than 660s. 4 years ago i had tested the stock engine and I got 219 HP @ 5000 rpm (whp). Length: 320cc, 440cc - 73 mm 550cc, 750cc - 78 mm 2-pin Mini timer plug is available for this injector from "Connectors" section of our Shop. Now, Holley EFI products power these cars and are dominating the performance world. These injectors will also be a direct fit for a twin cam RB30 built with a an RB26 head and intake. I will attempt to rewrite the page keeping what is relevant from the past, but discussing and comparing the newer technologies. I have the stock 1998 manifold and injectors on the engine. The MS3 Gold Box is a powerful, feature packed engine management system that the budget minded enthusiast has been waiting for. We found no option to perform as good as the OEM injector. For a 100% stock ecu your only real option is to use an airflow signal modifying device, such as a MAFT or a SAFC. Anyone have any experience running this size or larger? I am thinking more of the idle department more than anything. 9 R/T Fuel Injectors IP: Logged Message: I've recently upgraded my intake, throttle body, transmission, etc and I want to upgrade my fuel injectors. ACCEL was even nice enough to supply us with information on how to choose the right size fuel injector (ACCEL or. Any +94 miata should have the wiggle room built in to idle +10/15% larger injectors. One of the tricks that I discovered for fooling the stock ECU is to fit much larger injectors and tighten the tension on the AFM's spring. Better yet, the process isn't all that difficult, so that even a newcomer could figure it out. Normally ppl adding light turbo+tunning+larger injectors only added 30hp~40hp. Lets say the air flow meter and injectors are designed to support double stock engine power. I honestly cant afford. If injector pulse width is too great, and throttle angle increases too suddenly, you will trigger fuel cut. Most EFI kits are supplied with wiring harness, sensors and throttle position sensor. The nonlinear range comes into play on bigger injectors, over 1,000 cc/min, when at idle or even part throttle situations depending on the size. I don't think that stock injector is so tiny to give all the extra fuel that is needed for an exhaust - air filter mod. At idle, at partial-throttle and at full-throttle. Mitsubishi GTO J-spec TD05 EVO3 16G Turbo’s. No need to open the motor or mess with the injectors or tranny at 9PSI, just run 93 Octane and a fuel tuning system (SAFC, MAPECU, etc - I can help you pick the best option for your ECU). You can run larger injectors on a stock tune but it's going to either bog down, or flood the engine. Very flexible- easily tune for larger injectors, bigger cams, stroker, high compression, ITBs, supercharger, turbo, nitrous… you name it!. As a rule of thumb on some stock ECU, it can only compensate for less than 20% of larger injectors than OEM injectors. The bike runs super smooth now, especially at slower speeds, the rpms seem to climb a little faster (thus accelerates a little faster). Pig rich, but is wiring in an SAFC to fix that #8 Just there is so many options when buying the injectors. You will want to set injector balance to 50/50 using ecueditor for big hp stuff on the stock injectors. 7, and the ECU will got to the fuel map look up table calculate a leaner value and replace the old value in the table there for making the car run at 14. 5 pounds without any additional tuning needed. I think I always heard that the largest injector that could be run on a stock Honda ECU is 310cc. If you need to send us your EPROM ECU to be socketed, then be sure to select the Socket EPROM ECU option below. When it comes to replacing fuel injectors, step one is shopping at Summit Racing! We've got all the top brands—DeatschWerks, VENOM, ACDelco, Bosch, Delphi, FAST, and many others. But at what cost. Yes they work well. Discussion Starter • #1 • Jun 17, 2010. Hi Does anyone know the OEM injector size on a MY08 WRX, I believe they are 440cc or there abouts, I want to put bigger injectors in and thinking 550cc pink STi ones but if the stock WRX are this size may have to go bigger again. I honestly cant afford. Can somebody tell me what size the stock injectors are on a usdm H22A1? Also, does anybody know if the jdm H22A uses different size injectors? I have been trying to figure out why I am having problems when I run my usdm H22A1 on a jdm p13 ecu. Injectors have a duty cycle and you should not exceed 80%, if you do then you have to bigger injector. Remove O-ring 3. Currently on stock ecu,stock. 75 LB/HR per cylinder. Any injector larger than 60lbs must be scaled to work on a stock 03-04 EEC in order to be tuned correctly, but it will work. Engine aspiration, {Turbocharged, Supercharged, and Naturally Aspirated engines have different BSFC’s (see Glossary of Terms for definitions)} Desired horsepower, (The amount of power you. 315 cc injectors are way too much for stock ECU to compensate. 7 to 1 compressionfrom milled head 30 thousndths. The stock ECU at WOT will still run at the same duty cycle as before as it still believes it's driving 360cc injectors. 672 g/sec or 29. 8 to try it. These devices really aren't helpful for *adding* more fuel, as the stock ECU will use the injectors for all they're worth. I think those TSB cars also got ever so slightly bigger fuel injectors installed too. Re: Bigger injectors on stock ECU - Part 2 (Goobery69) 12-02-2001 06:26 PM #17 I'm very interested, because I have a set of Mustangs 26 lb injectors and it may help the problem of fueling in my SC VR6. If you have 440cc, then no larger than 880cc, assuming you are not talking about pump gas, not E85. I am not getting a whole lot of help here. This could make the idle rough or cause the car to frequently stall. Rad,cool bypass, kooks headers and t/d's with cats on the way,and 3. Ford Mustang 8693 MegaSquirt Gen2 Plug and Play for the 1986-1993 Ford Mustang 5. the ecu can automatically adust for fueling. 2017 Grom – Honda went with a different injector, fuel pump, and ECU. On a stock ECU you will be lucky if the car runs at all with those injectors. of 307 horsepower (BSFC of. I have also installed larger injectors which the emanage controls ok. 8 Bar Boost. you can usually get around this by tuning the ecu correctly, but that just negates the effect of teh injectors themselves, because they cant open up wide to. Mustang Stock Fuel Injector Size Chart. on the usdm ecus (type s and si) they not only disable the fuel pump but the injectors the injector power is built into the ecu which provides the pulse to the injectors to squirt the injectors at the right time for each cylinder. I have spoken to many people out there who have said repeatedly that teh 2. Full Force Diesel performance injectors are one of the major upgrades to improve the performance and power to the 7. Correction factor is only -30%. Without this, your car would hesitate when you stepped on the gas. Purchase Maptuner X. I don't think that stock injector is so tiny to give all the extra fuel that is needed for an exhaust - air filter mod. By far the biggest caveat is how the stock ECU scales injector scaling! See below!!! Injector Scaling and Interpolation So quick bit of background, the injector scaling is represented in the ECU as a "raw" number, only in ecuflash does it bear some resembalence to how big your injectors are. 3 Powerstroke Performance Engines Pure Diesel Power carries a full line of performance and OE replacement parts for 1994-2003 Ford 7. The stock injectors run at about the same lb/hr, with a fuel pressure of 58. Some people above have suggested upgrading to a 440-450cc injector. Nomad, so i have the hitachi ecu? u12 ECU? i have a t3/t4 and bought 550cc injectors and a 255 fuel pump but havent installed. By Patrick Rall - February 21, 2020. We are running 750cc on our turbo R53 with -1. Some of them modify the injector duty cycle control signals as they travel from the ECU to the injectors. When flash software, a stand-alone replacement, or a chip tune is not available for your ECU, a Piggyback (PB) system may be an alternative to extract any hidden horsepower and compensate for larger injectors when there is a need to upgrade. Choose top quality brands AC Delco, AUS Injection, BWD Automotive, Bosch, CARQUEST, GB Remanufacturing, Replacement, Standard Motor Products. Re: Bigger nozzles in stock BMW M57N injectors Post by Siller » Wed Oct 24, 2018 5:59 am So if I understand correctly and want to install EU4 injector nozzles on EU3 injector, then I should bench test those as 216 injectors (if i take nozzles from 216 injector) and if they qualify as EU4 216 injectors then it should be okay?. I remember way back when people used to use the Celica injectors, Apexi Neo/SAFC and a J&S Safeguard for timing. Under the seat locate the ECU service check connector, if you have a pre-04 VTX then you are looking for a 3 pin black plug with 2 wires (green and brown) entering the back (see pic). For example, if the programmed injector pulse-width at a given RPM is only capable of reaching a 65% duty cycle, that is the maximum duty cycle you can get. larger injectors = more fuel flow. There are a number of ways to tune the stock ecu, depending on how you choose to do it: Option 1:. 5 ecu and the 2. Adjusting the MAF rate is simply for smoke control. The R4 software has two map tables. With me just using an EWG, and tbe+intake(walbro too), my earlier tuner recommends to everybody going above a base stage2(tbe+intake) to use bigger injectors. With the addition of a larger turbo or with an intercooler, we suggest the 180cc option. Evolution Powersports bigger flow matched injectors to suit CanAm Maverick X3 tunes. Lowering the RPM at which the secondary injectors come on allows them to add fuel before the primary injectors start to max out. They are significantly larger and will dump enough fuel to cause issues. That is what it bases all of it's calculations on. my grand national came with 28lb/hr injectors(245hp @ the crank, but only a 6 cylinder). injectors and swapped them onto your new block. it can be alot leaner and make more power and torque. Can I fit bigger injectors that are around 450cc or 500cc? Im not ready for a new ecu and tune yet. 99-05 cars and around 160 rwhp on 90-97 cars, give or take, based on octane, induction type, and tuning. My car is all stock and doesn't have a turbo and I herd a nice cheap mod I can add on for improved performance was bigger fuel injectors 1 people found this helpful. At the stock base pressure we could actually use a secondary injector in place of the primary. Its doesnt matter what ecu/piggyback you are running they will need to be at least checked and programmed to get max power. Less egts are also a bonus. is necessary to use other injectors. There are three options for ECU programming: 1. The bike is an 06 1000 running all 8 stock injectors. Blue lines: After with Intake, Exhaust and MAP-ECU. You can't have bigger injectors and have no way of controlling them. Link to post Share on other sites. My stock injectors flowed ~300cc/min after I had them cleaned, I think they tested at 43. injectors and swapped them onto your new block. Re: Bigger nozzles in stock BMW M57N injectors Post by Siller » Wed Oct 24, 2018 5:59 am So if I understand correctly and want to install EU4 injector nozzles on EU3 injector, then I should bench test those as 216 injectors (if i take nozzles from 216 injector) and if they qualify as EU4 216 injectors then it should be okay?. We are running 750cc on our turbo R53 with -1. Mitsubishi 3000GT, standard UK spec Red lines: stock vehicle @ 0. I was always under the impression that the usdm and. This kit is designed for the L28 fuel injection engine but can also be used on L24/L26 if you upgrade the fuel system (high pressure) and use an L28 manifold with injectors. Some lads will say "oh go for the "1000cc, Bigger is better" and other lads say "stay with 650cc and it will run nicer". I've never seen a reason to go with a smaller injector. Some of them modify the injector duty cycle control signals as they travel from the ECU to the injectors. 2 and sometimes it would idle 12. To switch back and forth between gas and E85 you also need some sort of tuner. Obviously the larger you go in injector size you can count on the timing going higher and higher if you are just tricking the ecu with a piggyback. Most tuners can get it to around 600 hp with stock internals by converting it to single turbo, changing the ECU and adding some bigger injectors along a less resistive exhaust. (Stock flow/Y)^2 (bar) So in order to compensate larger injectors the fuel pressure is adjusted to a lower pressure. Getting your flashed is a great way to improve performance, realaibility and response. Ok probably a dumb question but can I run larger injectors on a stock turbo ECU? Matching impedance of course and specifically 420CC turbo supra injectors? I'm pretty sure I'll need to get nistune to run them, but I figured I would ask if it gets my swap done any quicker. 73motives that need to be installed! It runs pretty good, I just dont want to be to lean!. 1 or richer, when you can force more air into the engine at high engine speed with the FPR responding to increase the injection pressure proportional to the boost. FM cowl intake and a timing wheel running 12-14 degrees advance on 91 octane. Mountune does not supply the necessary characterization data for the upgraded injectors. i have a chip but was for my old set up of 30lb injectors, 73c&l. This is because the ECU controls the duration of the opening and closing of the injectors; if the stock ECU is used, it will flood the engine with fuel. The nominal injection pressure for many Ford EFI systems is 39. I have spoken to many people out there who have said repeatedly that teh 2. but it is not a good idea to upgrade injectors without some type of engine management. Increased factory deadtime resolution from 15 usecs to 1 usecs. 7 V through a 6 ohm load resistor (Rload, a 5 W ceramic power resistor, bonded to the case of the ECU to act as a heat sink). I figured on average the Evo fuel pressure is about 35psi base, hence the small scalings for large injectors (I. Holley® has been the undisputed leader in fuel systems for over 100 years. 1st good event. FYI, 2nd Gen Ford Lightning use 42# injectors (rated at the standard 43. The biggest injectors anyone is running on the stock ecu is 485cc's by cain. 6 Bar Boost. you need high impedence injectors so you do not burn out the injector drivers. Car runs great and I plan to get ECUtek, modify my injectors, get a fuel pump, Electronic boost controller, and so defi gauges. The combo of Yosh pipe, Mtake, Bazzaz, and cam took this bike from 8 to 12. 827 165 43. I think I always heard that the largest injector that could be run on a stock Honda ECU is 310cc. The engine control unit (ECU), fuel and O2 sensors, and the fuel pressure regulator are all working together to maintain the proper air-fuel ratio (AFR) for optimum engine. Again, we tested a variety of injectors at length. 2 Carefully cut back the tape and covering material on the injector wires. What injectors should I fit? Is it a case of Bigger the Better? or is there an ideal injector size to fit?. Larger injectors with a heavier pintle also take longer to open and close due to inertia and show a similar effect. 550cc injectors in-tank fuel pump mines ecu - not sure if this is the right choice. The Gencoupe Store is proud to offer the hands down best ecu flashing service for the BK1 2. We offer a wide range of high quality injectors and other accessories - from our stock, quickly and cheaply! BIGGER QUANTITIES, BETTER PRICES We are mainly specialiced in Bosch products and other electrical stuff. The Apex'i Super-AFC is a good example of this type of device. the reason is Injectors open for a certain amount of time and spray fuel but if the injector is open and the size of the nozzle is bigger then more fuel comes out. now its the MSD (rochester injector of 1000cc). 5-2002 Dodge 5. The pulse width at idle will be about half of what it was before. The optimal flow of fuel is essential because the rich fuel mixture leads to power loss. They are a direct replacement for the stock injectors. I have yet to detect any detonation, and the bigger injectors (I installed RC Engineering 320 cc/min Lucas style injectors) are easily keeping up with things so far. Proper fuel pump selection is also important to the success of converting a fuel injection system over to alcohol. If a 15% pulley is thrown into the mix that means the stock injectors will be running at about 92% duty cycle. In preparation for my supercharger install, the install of 75 lb/hr injectors, and the ECM limit of 63. is necessary to use other injectors. It would work like a champ. The ECM is what is "calibrated" for the injector size which is why these "calibrated" MAF trick the ECM into thinking it is the stock size for those injectors (by way of changing the sampling tube). 62ms dead time in account the actual opening times would be 1. Mine has all the 121 big bore parts, just a little bigger bore, Venom plenum, 60 mm throttle body, valve spring upgrades, 585's cams, currently freedom headers with V&H 4 inch turn downs packing removed, carillo rods, crank balanced, little bigger local made pistons, have dynoed 3 times and moved up to hotter plugs , but still way to rich, I am thinking of putting stock injectors back in re. These are a high resistance injector, so they can be used with all after market ECU’s without the need to use ballast resistors. The engine control unit (ECU), fuel and O2 sensors, and the fuel pressure regulator are all working together to maintain the proper air-fuel ratio (AFR) for optimum engine. Or even a model number and all of the specs about the stock one so maybe I can Find one that will work. Idle remains good, throttle response until boost is achieved remains good then when boost is applied the secondary ECU simply compensates for the boost by adding fuel at that time. 6 -25% fuel trim, my minimum pulse width is. That'll probably be a good choice. Also the flow data coded into the engine ECU will cause multiple issues with the control of the injector. 2001 IS300, Low boost on stock ECU? Jump to Latest Follow 1 - 20 of 21 Posts. However the stock ECU limits the injectors duty cycle to around. Currently on stock ecu,stock. 6 ECU should be able to idle up to 305cc injectors. Pry off nozzle as carefully as possible. These are very inexpensive, simple, and reliable. Those injectors, maxed to their extreme limit (100%), will support approximately 420HP* at stock fuel pressures. Under the seat locate the ECU service check connector, if you have a pre-04 VTX then you are looking for a 3 pin black plug with 2 wires (green and brown) entering the back (see pic). Again a bit of a toss up especially if someone installs a performance cam in which case bigger than stock injectors will be required. Obviously the larger you go in injector size you can count on the timing going higher and higher if you are just tricking the ecu with a piggyback. So, for stock 24# injectors running at 60psi of fuel pressure, you'd do 60 / 43. Does not appear a problem at the moment but I want to be safe and in future the performance mods i will do will probably require bigger injectors anyhow so its an idea. 96 Bar Boost. No chip or anything of that nature. Larger injectors and a matching chip will allow the engine to run right up to the 300 horsepower level, after which the factory ECU becomes the limiting factor. You should EASILY make the 300hp mark with this set up with more response than the bigger 2871r. Through countless hours of dyno and road testing each one of these maps has been proven to outperform the competition in every way. These injectors will also be a direct fit for a twin cam RB30 built with a an RB26 head and intake. 2: put the same injectors as old mate had in there 3: get bigger injectors and get a retune. 2017 Grom - Honda went with a different injector, fuel pump, and ECU. This type of driver works by supplying 12 volts to the injectors and the ECU turns it on and off to establish a fuel injector pulse. RSR EFI Systems are sold several ways: First, we sell as a minimum the ECU, the wiring harness, user software and the sensors (air, coolant, tps, map, O2, IAC) for one to eight injectors. If you are placing the larger injectors on a stock engine, the gain is nil. Around 470 HP. The stock fuel system can handle substantially more horsepower than a port-injected car; we have seen over 400 whp on the stock high-pressure pump and injectors, and over 500 whp using E85 fuel. I have a 15% SC pulley, 4-2-1 manifold with high flow cat on a stock JCW R53 engine. It's from the larger injectors. I think I always heard that the largest injector that could be run on a stock Honda ECU is 310cc. The combo of Yosh pipe, Mtake, Bazzaz, and cam took this bike from 8 to 12. 2-pin Mini timer plug is available for this injector from "Connectors" section of our Shop. In fact you may even lose HP as the mixture gets even richer at WOT. 0L Power Stroke Diesel - Bigger injectors on almost stock truck? - Hey there, I think I have a bad injector, (or turbo seal) and was wandering if I had to change them, what I should go with. Hello Everyone, I appreciate your time and interest ahead of time. No aftermarket piggyback unit does much more than modify the stock ECU injector pulsewidth pattern. Replace the factory Electronic Control Unit ( ECU ) with a full standalone ECU. With the ECU leaning the LTFT and STFT when you go WOT in turn you will run. Looks like the rest will follow for fuel delivery (injector selection, FPR). I will be using the HP EFI system. 450cc injectors with a 20g turbo on. The problem is that they say, that tuning for upgraded injectors on the stock ECU would be a pain in the ass, can take a week and they are not interestend in spending that time for Gen (just 50-100 cars for almost 20kk city (unofficially) and would multiply the cost of tuning by 3, leaving me with about $1500 for a tune. In other words, this is the maximum you can go on stock injectors before you 'run out' of injector (or basically - fuel). Save Share Reply. just my point only. My question, I thought the Mugen ECU was supposed to run leaner than usual AND why do I get a CEL with the Stock ECU and when I put the Mugen ECU, it goes away. Watch this 25 year old DSM lay down 230HP with 227lbs of torque. I was always under the impression that the usdm and. However because the LH 2. 3 parts at very cost effective prices. as far as gains go they were decent from what i remember it was around 20hp or something like that plus 25 or so ft lbs. 0t/Z20NET models so the next stage requires fitting bigger injectors and either a) fitting a 3" downpipe (d/p) and sport cat which would allow mapping to 230hp/370nm or b) swap the stock GT2052 turbo (and coolant line) for an Aero TD04-14t and map to 250hp/370nm. You can't idle more than a 320 or so injector with the stock ECU. i was thinking of finding injectors that flow 10% more on an old used car so we can have a junkyard $100 major upgrade that will likely beat ecu upgrades btw anything over 10% bigger is the max you should have on a stock ecu too much gas is bad python sells stock injectors rebuilt to flow 10% more but these are seriously pricey. 7:1 AF for any kind of cruising/idle etc. With me just using an EWG, and tbe+intake(walbro too), my earlier tuner recommends to everybody going above a base stage2(tbe+intake) to use bigger injectors. I have a 2006 f350 with 77k. If you think you need more filter area than the stock filter provides, the UZ series engine oil filter will fit and have about 48% more internal volume than the stock 4AGE filter. The injectors are driven by the ECU. 6 Bar Boost. I also found some. Specially calibrated for 100% drop-in install and replace stock injectors on the Abarth. i dont think he wants to turbo the car i think he was askin about just boosting the hp a little with injectors. hence flooding. 9 R/T Fuel Injectors IP: Logged Message: I've recently upgraded my intake, throttle body, transmission, etc and I want to upgrade my fuel injectors. Looking for used fuel injectors from other cars is a good way to find larger injectors much cheaper than buying them new. I will be using the HP EFI system. Stock ECU / Piggyback Options to manage 3000GT fuel injectors. The ability to cope with performance upgrades such as larger injectors while retaining the stock ECU. They usually also will make sets in the 750cc range for up to 350-400whp, and the 1000cc range for 400+hp engines. 3 Capri, Turbo 2. Ok, so I am on the stock ECU, no stage 05. I was under the impression most stock ECU's could compensate for injectors 10% larger but if the stock ECU is proven to withstand 310cc then that is a fact. The are some discrepancies with injector flow ratings because some are rated at 43 psi and GM tends to do things at 58 psi but it should get you in the ball park. 62ms dead time in account the actual opening times would be 1. The biggest injectors anyone is running on the stock ecu is 485cc's by cain. We found no option to perform as good as the OEM injector. If you install larger fuel injectors with a tune, you won't flow more fuel into the engine because the computer will adjust the flow of fuel accordingly. The pulse width at idle will be about half of what it was before. The 2000 ecu will handles cell values up to 254 lbs/hr so even the 160 injectors can be inputted. For example, if the programmed injector pulse-width at a given RPM is only capable of reaching a 65% duty cycle, that is the maximum duty cycle you can get. the reason is Injectors open for a certain amount of time and spray fuel but if the injector is open and the size of the nozzle is bigger then more fuel comes out. When using stock injectors with Petrol fuel, this value DOES NOT need to be altered. To work with the fuel pocket on the piston. I run Z32 maf w/ 60lb injectors all controlled by S-AFC and stock ecu. Furthermore, the OEM ECU will not be able to handle an injector that is more than 20% larger than stock and will suspect that one or more of its sensors are faulty and will revert to its programmed settings, which means that the fuel air mixture will not be optimal and will probably be rich as this is the failsafe setting on the ECU when it. In order for the ECU to supply the correct amount of fuel, it'll have to only send half the pulse width which in this case would be 1msbut this is 50% less than the stock setup. 3 Capri, Turbo 2. 1 injectors? I'm hoping to start a discussion here about what level of HP requires going to bigger injectors, and if so which ones to use. With the addition of a larger turbo or with an intercooler, we suggest the 180cc option. Nomad, so i have the hitachi ecu? u12 ECU? i have a t3/t4 and bought 550cc injectors and a 255 fuel pump but havent installed. 155cc, 175cc, etc. MAP-ECU @ 0. I don't know about Z's in the 70;s but modern cars limit to 25 to 30 % positive or negative change based on O2 sensor. If its near 100% its time for bigger injectors. The FlashPro will lock to and work with the FN2 GroupN / FD2 Type R ECUs perfectly. This way, you can run as much as 7-8psi as well. The 55 injectors are used in almost all AMG vehicles. If the injector ground circuit is turned on the fuel is sprayed at the back of the intake valve. In the end your air fuel ratio at any given RPM/load is set by the map/tune on the ECU. You will need to use low impedance (low z, 2-4 Ohm) injectors only. The BASE* fuel pressure you will run (your fuel pressure at idle), *our calculator assumes a 1:1 rising rate fuel pressure regulator for turbo applications. With me just using an EWG, and tbe+intake(walbro too), my earlier tuner recommends to everybody going above a base stage2(tbe+intake) to use bigger injectors. The R4 software has two map tables. The purpose of this article is to talk about the differences of the two and also go over some pro’s and con’s of both set-ups. Getting your flashed is a great way to improve performance, realaibility and response. So all fuel mapping in the ECU for the bigger injector has to stick with it, can't swap programs or injectors around, it now matches and has to stay together. When upgrading injectors or pushing past the limits of the stock AGU MAF sensor, we recommend the MK3 VR6 OBD2 2. It's from the larger injectors. Some people above have suggested upgrading to a 440-450cc injector. Once the engine gets to about 400 rpm the ECU will stop using this map and switch over to regular pulse width calculations. Your engine is not getting enough fuel at high RPMs and the injectors are at 100% duty cycle. the fuel rate and curve can only correct itself so much. Purchase a new pre programmed ECU "Õ with this option, you can keep your stock ECU as a spare. 5lb injectors. The stock injectors run at about the same lb/hr, with a fuel pressure of 58. Product Description. Looks like the rest will follow for fuel delivery (injector selection, FPR). It's time for new injectors, and I'm wanting to go bigger. 2020 Maverick X3 195 HP TURBO RR Stock Injector ECU Programming by EVP: The 2020 Can Am X3 RR is so good that it deserved an enhanced dyno testing and field testing regimen to make sure our tuning is the best available anywhere. We carry very innovative products for the SVO, Merkur XR4TI, Thunderbird Turbo Coupe, Turbo 2. Essentially this value is how the ECU determines what amount of fuel is needed at WOT vs. Shudder and smoke returned. But there are limits - and of course it can't do anything about atomization of a small amount of fuel from a large injector vs. the secondary injectors may use E85 or race gas). The purpose of this article is to talk about the differences of the two and also go over some pro’s and con’s of both set-ups. From personal experience, with 550cc/min injectors and a 3-bar MAP, my car idles just like stock. 5:1) Sprintex 335 Intercooled Supercharger System, Injectors. I was looking into the Terminator Stealth EFI for a Ford truck project that I'm building a 418W stroker for. dotn need injectors anyway stock ecu can be run on td04 at 10/12psi with fpr on stock 295s just set it up properly mate of mine has a td04 starlet at 0. 7 @ 132mph on 116oct. At the very least an ECU reprogram will be absolutely necessary. My question, I thought the Mugen ECU was supposed to run leaner than usual AND why do I get a CEL with the Stock ECU and when I put the Mugen ECU, it goes away. I think I always heard that the largest injector that could be run on a stock Honda ECU is 310cc. Re: Best Injectors to use with stock MSM ECU ? « Reply #5 on: December 01, 2014, 06:25:30 PM » Speaking as one who has done it the bigger injectors work a little nicer and will allow you to turn up the boost to 10 psi while still maintaining good AF readings. hence flooding. If they are getting hotter than that I would think that the box is not working right and that your ecu is providing the current to injectors and will be damaged. Without this, your car would hesitate when you stepped on the gas. Optional items you may have purchased are larger fuel injec-tors (if you are running more boost than your stock injectors can handle), an electronic boost control solenoid (BCS) if you have a turbocharged car and wish to use electronic boost control (EBC), and the Data Log Lab software for graphing datalogs. And basically a better stock tune format to start with vs. It's about 26% larger than OEM injectors. 535" inside diameter [about 17/32" or 13. This proves to be a problem, as the timing is advanced in the upper RPM range the numbers that the MAF delivers to the ECM for fuel trim are way. Pico injectors 250cc, 330cc and 480cc at 12 ohm impedance. Introducing the Holley EFI Programmable 8 Channel Injector Driver Module. Salve, I have a VW Jetta 1999 TDI engine code ALH, 220. I'm running the stock ECU (trying to keep the car relatively Cal legal) I was wondering if the stock 265cc injectors will be enough or if bumping to 305cc would even be a benefit or just cause bad idle and rich AFR?. 3 Powerstroke Performance Engines Pure Diesel Power carries a full line of performance and OE replacement parts for 1994-2003 Ford 7. At the stock base pressure we could actually use a secondary injector in place of the primary. After the first pull we were pretty floored by the numbers, the car made 269 Peak HP and 272 Peak Torque. With a tune, the stock ECU isn't the stock ECU any more. What issues will i have problems with? car: 00civic dx/ y7 to y8 mini me crower 2 n/a,springs+retainers intake,header,exhaust,60mm tb 10. ThanksJim August 6th, 2013, 17:28. High-resolution 486 point table allows fine tuning of performance and driveability. Bosch injectors 320cc, 440cc, 550cc and 750cc at 12 ohm impedance. 56 480/850 or 56%. Therefore, when the driver transistor turns on, there is an additional 0. I have yet to detect any detonation, and the bigger injectors (I installed RC Engineering 320 cc/min Lucas style injectors) are easily keeping up with things so far. If you plan on going over 330bhp, then plan on needing a larger MAF body and larger injectors. it will just overfuel if not tuned for it. is necessary to use other injectors. The factory fuel injectors will support up to around 200 rwhp on. This is because the ECU controls the duration of the opening and closing of the injectors; if the stock ECU is used, it will flood the engine with fuel. I will be using the HP EFI system. Injectors aren't sensors that can see how much fuel it's putting in, it can only see if it's completing a circuit when the ecu wants it to fire. To my knowledge it (particularly the Delco) doesn't have a way to measure fuel rates, they're set by the tuner. I wanna do a supercharger anyway (not till later this. An injector used in a saturated driver system requires a high resistance value across its coil (12-16 ohms). For the 19891992 models, BBK PN 1537 is the 52mm unit and PN 1539 is.
