Hi Ross, yes the engine is back in the car and in break-in period right now. I noticed my O2 sensor was cutted the wires when took out the engine for repair, we think it's a bosch WB sensor but we are unsure. Anyways, I would like to know if this M800 has a build in WB processor or do I need separate WB module-sensor to connect the M800 with it and tune up from there!?
Thanks
