R34 Gt-t Ecu Into S2 Rs4-s?

[CL11QE]

Hey guys im having some probs with my car atm, and im trying to isolate possible

causes, one of these possibly being the ECU. My friend has his standard R34 ECU

as he has upgraded to a PFC, so im basically wondering will this fit or work in my

car?

I am sure there will be some differences but I can't see it would do any harm to plug it in and try, carefully at first.

the R34 and S2 stagea dont share ecu p/n's in nissan fast. there have been a few people on here that have found the R34 ecu pinout isn't the same as the stagea ecu, i've been looking for wires using a R34 ecu pinout and a couple of the wires didn't match, fuel pump signal was one from memory. but then don't R34 powerfc's work on manual stagea's, with the exception of the engine check light?

I note you didn't say if your mate's was a GTT (sorry - i see it is in the heading - yep give it a try).

(BTW Josh I can send you the S1 Stagea pinout if you want a look at it).

yeh thats right i think pin 51 Nick said? hmmmm

my RS4-S runs a R34 GTT power fc just fine (or is it the other way around?) although you need to fix the engine check light though with a resistor.

Not sure if this means that a standard ecu would do it though.

CL11QUE i have the factory RS4S ecu sitting here in the Hills if you want to try it. The PowerFC is running the RS4S for years now so the pinouts are identical (with the exception of traction control....ie pin 51)

Hahaha, I knew you would turn up, Andrew! I was saying to Alex (CL11QE) that you would be the best person to ask.

Yeh that would be cool if i could borrow it for a week to see if it makes a difference, where abouts you at?

I dont live in the hills anymore but i still work in the area.
