Can I use an M6 obd2 pcm in an A4 if I get it reprogramed? Can this even be done, or do I have to get a A4 pcm for this to work? I'm building a new motor and instead of having the downtime I wanted to get an Obd2 pcm on the side.

 

no it wont know when to shift...the other way around will work though...

 

So if I send it away for a mail order tune they cant program it to work in a A4?

 

yes they can...i missed that in your first post...

 

Ok, so let me get this straight before I buy it. I can get an obd2 M6 pcm send it to get reprogramed and then use it to work in my a4?

 

Yes. A PCM is a PCM. It's the program that is the difference and I'm sure they have a stock A4 program to start from.

 

Is this something that could be done with tunercat by simply flashing an A4 file to it?

 

Yes.

 

I didn't realize that Tunercat also programmed OBD2, it thought only OBD1.

 

i was asking about OBD1. But yes, they have OBD2 software out now.

 

Jet Performance bought the program. TunerCat does not sell the program anymore.
