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

cool thanks, do you reckon the 6s was a noticeable differance?

[Leighos]

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

[gazzy2000]

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.

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

...

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.
