I have the chance to pick up an apr stage 3 ecu with the correct injectors and maf. Now if this ecu was from a 2000 and has no esp i can still recode using vagcom to 06711 correct? Figured the you guys here would be the best at answering this.

ecu is 8D0 987 551 H but im guessing that was a typo and should 8D0 907 551 H

I may be asking about this in the near future, but was just told the ecu came from a car with esp so should be all set. Im assuming its like reading and modifying the immo chip? Any good sources to read up on just in case I have to go this route?

one quick question, I'm buttoning up my swap and was just curious. Would I be able to write the 95040 on the apr ecu? Say i wanted to retrofit my immo that is in the b6 body, would I be able to write the rs4 95040 with the skc from 1.8 ecu that came out? I read this but wanted to be sure http://nefariousmotorsports.com/forum/index.php?topic=2973.0

edit nvm reread and realized theis would mean I have to flash the ecu as well with a bin the references the immo not just the 95040 flash so a no go.

I've always understood that APR ties there tune / ECU to the original car.  I don't know how that could be bypassed, or if it can be bypassed, but I do know that DDillenger, Nyet, Turbo..  will know better than I.

BTW, I have recently learned, through experience and advise given by DDillenger and Nyet, that it's, at times, best to toss & trash these tunes, as they can be generic, cookie-cutter crap!

Good luck to you!

If you are looking for reliable tune you should go custom - off the shelf tunes are not even close to what you are looking for at least in my opinion.

Probably means north american.
