I have this document on the TS ECU for 75 and 164 that I think could be really useful. I can kind of work out about half of it but would someone be willing to translate the whole document? I think it could be a great resource.
I tried to attach as a PDF but it's too big and the forum won't let me attach a .zip file so it's going to have to be the 14 pages separately.
Next four...
Next three...
Last three.
Its been almost 40 years since my last Italian class, so I can't help directly. I know it would come out pretty garbled, but are you able to copy the actual text (from your PDF) into Google Translate?
Tried running it by Goggle translate??
Seriously? It's talking first about how to extract and read Motronic flash codes, plenty of info in Inglese to be had out there.
Then about identifying different variations of the ECU, whether Pin 11 is earthed or un-grounded being a determinant.
Also showing the different forms of diagnostic connector access.
