installed a power fc into r34 gtr and wont start.... as per my post last week....

spent a week checking wiring etc......etc...

any one know or had experience with the immobilizer unit in r34 gtrs before..

even how to bypass or hot wire it....

another guy in the uk gtr forum had the same problemb as mine and it was the immobilizer...he ended up using an r33 gtr power fc in his r34 gtr but found out later that it can be bypassed or reset....

cheers...

G'day Mark,

You may have already checked this, but have to disabled the boost control module through the handset ??

The PFC's are defaulted with the boost control module 'on'. But if you don't actually have a PFC boost solenoid conected, it won't let you start the car.

Have a read on the handset manual and make sure the boost control module function is turned off.

Cheers

hmmm i fitted one in mine and it started first go...the only problem i had was the engine check light comes on.....mark if you plug in the commander does it light up and come on air?I dont know about that jay...i didnt disable it on mine and it worked...although i have the boost controller i didnt hook it up and it still ran

have got all the setting correct in the power fc. etc etc...

the engine light goes out with or without the hand controller in....

my car has a mines ecu which is out of an r33 gtr with the crank angle wires swapped inside the ecu.. it runs fine.....

it must bypass the immobilizer somehow being earlier model ecu...

but put the r34 power fc in and no start.... all settings correct......

wish i knew how it controls the computer.(immobilizer)....

cheers...

On my car the PowerFC would only fail to start if the boost controller setting was incorrectly set to On.

yes we all know that....

its not so simple with r34 gtr... every setting in power fc is correct for running...

Hmmm mark do you have the original key for your car?I am just wondering if someone has fitted the earlier ecu it wouldnt have the facility for the body control module(of which you already know!)But hooking up a standard type(or power FC intended for the R34 with the facilitys for imobiliser wiring ect..)the transponder or lack of transponder will picked up via the BCM and send the cut signal to the R34 ECU...if you got the key look on the end and see the red tab...pry it out with a stanley blade and check if the transponder is present...

I know i am not really answering your questions but hope this helps :(

if u turn your car on so the radio and warning lights come on, does your fuel pump prime for the same lenght of time as it did with the stock ecu in??

coz i had this same problem coz the fuel pump would only prime for around 1 second and the car wouldnt start and any setting changes i made on the hand controller would not save when the ignition was turned off.

I had to get a new positive feed form the battery to the loom and it solved all the problems.

Hi

I would like to fit a power fc on my R34 GTR uk spec, but on uk cars there is no immobilizer fitted and it wouldn't start with the R34 GTR power fc.

In uk most tuners use a R33 GTR power fc with a special harness, but if possible I would prefer to use the R34 power fc if possible

Thanks

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
