Hey
I have a 4Z7907551R out of a A6 2.7t tip. The engine is swapped into a B6 A4 3.0 6spd. I was wondering if I need to flash this with 6 speed software or can I code it in vag com? Also which "box" is this, I think I've read that it is comparable and flashable with S4 mbox software.
Thanks
Sam
Recode is all you need. Towards the end here:
http://nefariousmotorsports.com/forum/index.php?topic=3325.0 is a good place to start.
551R is ME7.1.1, so no, you cannot swap M-box firmware on. 551R is the de facto standard for 2.7T ME7.1.1 so, while not as plentiful as M-box, there are plenty of resources (posts, files and people) on nefmoto to guide you.
