yea thanks, i saw those 1S ECUs in Kaminekos thread, but the numbers on this ECU are slightly different and not in his list.

So i guess the question is... do all 1S ECUs (regardless of teh other numbers) run yellows etc etc

on this one the model numbers are on a black lable

I've used an ECU with that exact part number in my single turbo conversion, using orange airflow meter and yellow injectors and it ran fine so I assume it was the correct combination.
Using a 6S now, much better  ;)

Yes noticeably different, I think the 6S has a higher rev limit also, but I'm not game to test that out.

I can confirm that a 7S will rev to 8200, constantly, persistently, and forever :)

even on a WRX block?!  ;D

I don't think so Jon. But on a STI block - yes. ;D

Looks like I meant a 75 - not a 7S - my bad - blame it on the poor eyesight. :)

GODDAMN i love these threads  :D

hey, i used the search and found nothing on this ecu, can anyone help?

1S 22611 AC720

A18-000 D28 6Z10

i know its a 97 GC8 but thats all, does it run yellows and a orange AFM?

cheers

YES. That ECU listing has all the info you need, have a read further down. quoted for truth  :P

...
VER    MODEL    SPEC      TRANS    ECU    ECU PART         AFM
Ver2    GC8C     STI-RA    MT           7K      AC710   D22       AA160   Green           

7K                     =  reference code for easy identification.
22611 AC710      = This is the Subaru Part number for this ECU.
                             22611 (ECU part category)
                             AC710 (Part revision)
A18-000-D22      = Unisia Jecs part number. (Jecs builds the ECU for Subaru)
                             D22 (Part revision) this number is usually found on a sticker on the socket. This ties the
                             case to the ECU board. [up to version 3 afaik]
5X11                  = ECU serial number

note: sometimes the ECU revision may be out by a few numbers eg. AC710 -> AC711 This is the same ECU with a minor revision, possibly to the tune.
...



Yes noticeably different, I think the 6S has a higher rev limit also, but I'm not game to test that out.
