Summary of change:
I'll be converting my Volvo V70 XR AWD over to VEMS to take advantage of the Precision PTE 6262BB turbo I am installing. I plan to build the VEMS 3.6 into a Motronic ECU case and use as much of the stock wiring as possible. http://i27.photobucket.com/albums/c190/huseinholland/CarMods/IMG_9364.jpg I already have a separate COP setup through TurboTunerUSB, so I will need to include new wiring from unused pins in the ECU for the logic level outputs. I plan to leave a stock (modified for no CEL reporting) ECU in a bridge connector to retain the instrumentation & basic OBDII output for state inspection purposes I want to retain items from the existing ME4.4 such as the AC/2 speed fan functionality, Barometric pressure compensation, dual knock sensors and Accelerometer (if possible). The main item I have to add is the MAP/MAT, I'm going to use the Bosch/VW item. I can repurpose existing wiring from the EVAP valve for that. The WB02 will be installed in place of the existing rear O2, I just have to add one wire to the stock harness for that. Main Engine harness mostly ready.
