I am building an endurance race car (model mentioned above) I plan to purchase a ECU Master EMU Black. I purchased the entire wiring harness courses on HP Academy. I am preparing to build my own harness. I am a total newb and have little to no knowledge but I ruined the cars original harness and don't want to spend more money fixing an old system. My question is this. I want to remove anything from the engine / electronics that I do not need. The only factory BMW assist I want to keep is the ABS. Can someone help me with a lists of things that I need to delete ie evap valve, idle control valve, secondary air pump, fuel tank leak detection module, exhaust flap valve, etc.... TIA!!
