R34 Pfc Doesnt Run All S1

[Duncan]

not yet but good point - I will make sure they check the pfc as well (hope its not stuffed they are kinda rare). but if it is injector wiring that is different that would explaint it.....

Duncan, if they need another R34 PFC to compare (although they probably have a few @ Hills), let me know and I will take mine there to hopefully help sort it out.

Good luck Brendan, I'm sure it'll all be sweet though

[Duncan]

actually nick if i get organised i might try your pfc in my car and see if we get the same result....

Not a problem.

Any updates on this? really interested to know what happened

[Duncan]

yes kind of. the workshop are working through the loom and should have the changes by the end of the week. It is not even close though, for example 02 sensors in the wrong place etc

[beastien]

Something strange going on there, What year/month was yours manufactured?

Looking in FAST it's possible there was an ECU difference in the S1's.

[Duncan]

yeah well thats wierd. mine is 10/97 which isn't really early series 1 in fact it is pretty late I think.

anyway i will keep everyone posted on what we find out

[Duncan]

just to add part# for ecu for mine from FAST is 23740-0V310

[beastien]

From what I can see in FAST for S1's the original ECU was P/N: 23740-0V300, then it changed to 23740-0V301, then to 23740-0V310,

and then there's an alternate number which is 2374M-0V310.

Doesn't explain much though, and you wouldn't think the wiring would change.

Ah well, will wait to see what differences there is.

[GoldZilla]

I just had a look at a pic I took of my ECU ages ago, and it has 23740-0V300 on it...

[Duncan]

which was your part # brendan? this is becoming a bit of a pain. I'll look into loom part numbers and see if they changed too

[Tangles]

Ive got an early model stock ECU, so she'll be right

however Im thinking I dont want to rebuild the auto in a few years time, whilst the p-fc will run my car (auto+shiftkit) I might just do a remap.

If anyone wants a R34 GTT Power-fc with hand controller, working order, top condition, contact me

[Duncan]

hmm well there you go. 3 engine harness part numbers for rb25det

09/96 - 08/97 24011-0V100

08/97 - 09/97 24011-0V200

09/97 - 08/98 24011-0V201

fast shows my vin as the last one

[mitchy_]

wonder why they changed them... and why they only used the second loom for a month...

[Duncan]

yeah sucks to have one of them, eh? this info is from FAST, but it just says there is a difference, not what the difference is

[beastien]

Part number for mine is 23740-0V300, the strange thing is though, the service manual only has one pinout diagram for S1's.

[Duncan]

yeah thats the difference then.

The service manual thing was what started us in the wrong direction (only has 1 pinout and we started with that) but it is not correct for my car. Might be that they released the service manual at the same time as the car and didn't update it for later changes (or there might be a bulletin or later manual that shows both)

[Scratch]

Did they (the workshop) finally work it out duncan? or is it still being re-wired?
