build page on FB as W12B7AVANT. ECM's were a pain. Madness Motorsports was able to modify my files so i could run the manual transmission and a tuner in US is fine tuning everything once i am able to get some runs logged. ECM's are factory. No aftermarket ECM's available for this engine setup....2 throttle bodies, 4 knock sensors 12 injectors and 12 coils. I talk to several aftermarket ecm companies. My ECM's are ME7.1.1 with the infineon processor. They are easy to work with. I also have a set with the ST10 processor but they are a pain to remove the immobilizer and get into boot mode.

Ahhhh I thought that I recognized your handle. You, the German mail truck, and the hungarian a4 are the only 3 confirmed builds that I could find with a w12 in the world!

Thanks for the info. That is a heck of an undertaking.

Gear head went with a twin turbo ABZ setup running KKK turbos and a VEMS from EFI direct. His build thread is in progress, time trial aero build is the name of it. He's finishing up the exhaust now, and I'm starting to think his actual goal is to build a rocket ship!

I haven't seen the Hungarian swap. Got more information on that one? Quick search pulled nothing.

Definitely a challenging swap. Ive wanted to swap this engine forever and was lucky enough to find a whole car really cheap...like 1k cheap. Car had damage to bumper and core support but ran.

Currently Im having to redo the radiator since i goofed up a couple weeks ago and let a strut fall off the press and ruin my radiator. worked out great though, the new radiator is smaller and fits into the original core support. Once i get the car done and working well, i plan on swapping in the W12TT from a Bentley. Im running Bentley exhaust manifolds on mine now. Just need a little modification and the turbos will fit just fine in the B7 chassis.
