That is an unknown road, which your welcome to travel but I think the computer will trip out. Which is probably why HDDP is going with a full stand alone system in his gutted race car, probably best to start from scratch. AS I know HDDP has done many hours of research on this, yet he doesn't really post his findings.

I would much rather waite for LatanaTX to unlock his mercedes ecu, then that will prove I can just drop in the srt6 ecu, and be done with it. no need for piggback computers on top of multiple other computers, soon the data transfer rate will probably get bogged down.

Also how do you plan on operating the throttle body, with your by-passed ecus system? yeah you can feed the beast fuel and boost and play with the timing, but what makes you think the Motronic ecu will open it's mouth for you?
