Intredasting!

As I mentioned I'm hoping to do something cool this winter. I currently have an Audi 2.7tt sitting in my buddies garage, but I'm not sure that I want to deal with intercooler piping for two turbos. That same buddy also has a belt-drive 4.2L V8, so we'll see.

I recently did a 2.7tt swap into a B6 chassis A4 (the body style which came with the horrendous timing chain eating engine), so I've successfully pulled off a Motronic based swap and some of the wires you mentioned sound familiar. My Box is a 2003 so it's DBW which throws some confusion into the mix. But your wiring is a good help! Thank you!

Did you wire the OBDII/K-line connections to the GM ECU? I'm interested to see whether or not you can perform OBDII readings using the factory Porsche connection. Emissions testing around here is based on that function essentially.
