*Urgent* STI ECU numbers - how to tell its an STi V5/6 ECU??

[gazzy2000]

hey all,

I purchased a v5/6 ECU, just not sure its STI, how do you tell?

Numbers are

40

22611 AD983

A18-000 DOS 9616

Cheers

what you have there is a 1998-2000 legacy EJ208 twin turbo ECU

NOT WRX OR STI

you can find this by searching the part number "22611ad983"

and i confirmed this by a parts catalogue search

Thankyou very much for confirming that, i brought it through a guy on CS so i will be chatting to him.

If i find another one can i rely on you to check the numbers against your catalogue?

Cheers

That's very interesting, and you say you've had the car running on it after converting to single turbo? i'm just wondering how the fuel pump relay would work if that's the case...

If it is indeed a TT ecu, then that would explain the 10-12 psi... I should imagine it'd be throwing code 66 or whatever it is on OBD-II

Hmm, me too! maybe its a STI board inserted into an old ECU box?

[nt_a_foz]

who did you buy it off???

If it was who i think it was that i know just sold a sti v5 ecu then it was definatly one...

PM if you dont want to say it on here

Hey, it was from me, and is definately a v5 sti ecu in my old twin turbo case. Thought I would be nice and leave it in a case for you sorry about the confusion, but it ran perfectly single turbo for me I ran a gfb boost tap so can't comment on boost. I was too lazy to hook up the factory boost solenoid.

was gunna be my next question - pic of the board?

hey, thanks for clearing that up, yea i think i now recall you saying that you were going to do that, sorry to start throwing accusations around like that, but at least that is one thing to write off the list in the process of elimination.

Have you still go the factory boost solenoid? if so, is it a two or three port?

Cheers

[gazzy2000]

hey, does anyone know if the V5/6 STIs use a 3 port or a two port wastegate solenoid? and does anyone have a 3 port for sale?

CHeers

[wrx_lou]

three port noid bro.

[kamineko]

Ver5 GC8 F WRX MT A7 AE480 DL9?

WRX AT A8 AE491 D0Y?

STI MT J2 AF040 * D0Z?

GF8 F WRX MT A7 AE480 DL9?

WRX AT A8 AE491

Ver6 GC8 G WRX MT A7 AE480 DL9?

WRX AT A8 AE491

STI MT J2 AF041 * D0Z?

GF8 G WRX MT A7 AE480 DL9?

WRX AT A8 AE491

Dudes, get yourselves a cable so you can connect to a laptop. Then you can read the exact specs of whatever board is in there right down to the revision number of the software. You can tell what car, what year, what market, what version software.

[kamineko]

edit

what version ecu's give you more than just a hex firmware revision? are you talking bugeye+

[gazzy2000]

Hey,

So now that i knw it IS an STI ECU, it shud be boostin around 1 bar but its only 10-12 PSI, would the fact that i am running a 2 port wastegate noid when its meant to be a three port effect the boost pressure?

Cheers

[kamineko]

how did you confirm the ecu?

ecu numbers i mentioned before are only JDM. is this a NZDM ecu?

I took the guys word for it, he is a CS member and heaps of ppl vouched for him too.

If its NZ will it only be 10-12 PSI?

EDIT - it is a STI V5 board in a TT case

[kamineko]

what AFM are you running with it?

[gazzy2000]

the 2001 legacy GT-B BH5 one

If you have the wrong solenoid on it, the duty cycle will be wrong and it won't hold at the desired boost level as the 2-port and the 3-port are set up completely differently.

thats how he knows read teh thread nick

[kamineko]

yea my bad, found that post afterwards

[gazzy2000]

so chaps, can you tell me if the JDM and NZDM STI V5/6 models have factory boost rates at different PSI's?

[gotasuby]

its a jdm ecu as it has speed cut
