Hey,
I got an 2.7T Swap too. Are u still in the game? Did u fixed problems with the Speedsignal on Can? The Tank Clap problem is in mine too. And how do your car start? I got a button but then the rest of this C6 stands in ignition on not in KL.50 starting. Did u implementing the BBJ ECU. I Got 4Z7907551N BES ECU. My Car is a manual one. MAybe you could help me a bit.
There is arduaudi controler guys are developing for b7 platform with 2.7 swap they implement start signal via CAN , ac contrroll , fan control and cruise control look for it (i build my own with lcd) . For starter i hooked to ign lock to get 5v signal and enable relay im keeping it simple but i have heared that is possible me7.1.1 to output signal and cut when engine start ,but i dont need this . Update on post Car is now on Hybrid turbos and its driving good 15K+ KM. Still auto, little annoying , laggy and cuts boost till 3k but on S is perfect
