Identify ECU when sticker is no more
 

Hi guys,

About 8 years ago I bought a parts car S4 FC with 13BT swap. The car started but ran really bad and was not able to idle by itself. The swap was botched

Anyway, the seller told me he replaced the NA ECU by an S4 TII ecu. I was never able to verify this because the sticker is not visible anymore. Due to the poorly work done I'd like to verify by myself which ECU I have in hand.

So my question, is there a way to verify which ECU I have without the sticker?

I post some pics to help the identification.

Thanks,

Alex

S4 TII looks like.
look at the Jumper 600 in the bottom right corner.

IC 604 and IC 605 are also present.

Is it only the s4 TII ecu that has those caracteristics?

Thanks.

I would assume so.
If the IC chips were different the Ecu would have different capabilities...and the N/A doesn't have boost and the S5 needs electronic OMP signal from the ECU.
