Recommended Posts

Iv just put a Power FC ap engineering ECU on a r32 with a rb20det and the car wont start. The Fuel pump does not turn on and the hand controller will not turn on.

But if i put the stock ECU in it works and the fuel pump will turn on.

Any ideas????

Thanks

Steve

what's the product code? someone on here can tell you if that pfc suits your car? and did you buy it new or s/h?

its the right one, iv opened it up and it says rb20det, and its been seen running in another car over a year ago.

iv got a feeling its been fried?

Thats exactly what my one did when I fried it (put the battery terminals on back to front in a moment of insanity late one night)

Fuel pump wouldnt prime at all and hand controller would not turn on, I ended up getting it fixed but I cant remember the name of the company that did it, ill post in here if I work it out :P

Tested the ecu on another r32 and it works fine, so i dunno whats going on with this car????

we generally can repair these units when the polarity has been reversed.

but that seems to not be the issue...hows your battery?

what you mean?

i got another working pfc and put into this car and still didnt work.

i had this issue in my car, turns out it was to do with the 12v constant power to the pfc. i now have the issue of constant 12v to injector 1 which is stopping the pfc from saving settings.

if ya have someone who has test light and multimeter handy get them to check it out, i luckily had my r32 and my mates r32 side by side and we just compared looms and ran tests on each to isolate issue.

We tested the ECU plug against another r32 that the pfc works on and every thing came up the same!!! and still no step forward. The only thing iv found is the battery light does not turn on when the IGN is on and on the working car the battery light comes on???

check the basics on the r32 where the PFC doesnt work

its likely something simple is wrong (with the car, even tho stock ecu works)

the std ECU is a bit stupid vs the PFC and works with hacked setups

in the PFC FAQ (in my sig) look for a section on the ECCS relay

it shows how a mangle car works fine with the stock ecu but doesnt with the PFC

it shows how to correct it as well, from memory something with the ignition is wrong or theres a fuse missing

Had the exact same issue. only just fixed it. Turns out what the majority of people say is not always true. Series 1 and 2 r33's have a couple of different ecu pinouts. I swapped a couple of pins around and its all sweet!

Wow, read things before you post them. I cannot make any sense from this

    • Lighting in the shed looks real good! Not lying, have shed envy lol. Maybe one day I can fk off from Metro Sydney.
    • I would be cautious with those 2000/2200 CNG injectors, swap them out for a set of 1550 aka 1650 Bosch stainless ones before you take out a motor.
    • I tested them all a couple times, haven't tested it warm or wet though. The only seemingly really weird thing was the cylinders plug closest to the dash was pitch black nearly.  Doesn't smoke out of the exhaust or anything.    Also sorry everyone for the very late response. Got busy with work and all and didn't get around to fooling with the car for awhile.  But an update! I figured out the cause of the lean condition, my intercooler had at some point exploded or something. It's clearly separated in a spot with black oily buildup around the leak, and multiple leaks in various vacuum lines. I've replaced it and the vacuum lines, and gotten new clamps and there are 0 leaks now after doing a couple smoke tests.   The car now runs significantly better and the exhaust doesn't overheat anymore. I still have the main problem though where the engine feels like I'm lugging it around sub 3500rpm in any gear besides 1st, 2nd It's less noticeable but 3rd anything under 3.5k and I need to downshift or the engine is clearly struggling when trying to accelerate at all, 4th is the exact same, sub 3.5k engine won't accelerate and its hard to bring it back up to speed, 5th gear doesn't feel like the car is going to straight up fall apart now but it still can't pull 5th. It slowly loses speed and rpm and ANY gas I give I can feel the shakes from the engine and it slowly dying. If I ever so lightly give it gas it will slowly and nicely decel till around 2k rpm instead of lugging. But it cannot accelerate at all or maintain speed.   If I go from first gear at 5 or 6krpm and then shift to second it also feels like it's struggling to make power till above 3krpm if trying to accelerate but I can cruise around parking lots at around 1-2krpm just fine in 2nd. It's just when accelerating hard it and changing gear you really notice it die down.  But even if you shift at way lower rpms it does the same thing till somewhere above 3k.  As far as I'm aware it's got r32 gtr transmission gear ratios with gts4 diffs. The tire size is 205/55r16 91h Above 3500rpm the car pulls and runs and drives quite normally and the power from engine sounds and feels very smooth.  It's perfectly driveable at above 3.5krpm but I drive on the highway alot for work and it gets really bad gas mileage in 4th at 4.4krpm. Not that I'm looking for great gas mileage with such a car, just I'm sure being at around 3krpm would be significantly better for it.    Have appreciated all your guys help. I do understand the engine may just be f**ked from running with a boost leak though.    One final thing I'd like to add is I'm only shifting so high in the rpm range is because if I don't I will feel the engine lugging bad with 0 power in lower rpms, pretty much anytime off boost trying to accelerate it feels really bad.  Also when I say 3500 rpm I don't mean exactly. Just around there. 
    • So what did you end up doing ?  and is it still alive today ?    
    • I run 2 x 525 pumps on factory 8mm fuel lines     ... zero issues, staged of course    Your setup should work fine, all you need to do is find the restriction. A good aftermarket fuel regulator is always a good idea too. If it's not your regulator i'd be suspicious of your fuel tank breather and your tank pressurising. Next would be something with the fuel hat. Then blow out the fuel lines.
