brian, you may be able to help me out here. or someone else may too.
im turboing a 6 cylinder bmw. for engine management, i want to use gm ecu. i have talked about this, so now im going to do it. i know i can make it work.
i need the following–
typhoon/cyclone ecu and engine wiring harness, the air temp/water temp and 2 bar map sensor.
i figure cut the wires and make my own harness to length. i can get all the chip shit i need.
pretty much any gm harness/ecu will work. however, ty/cy harness is speed density setup–which is what i want. the ecu is also different plug wise iirc.
i could use a tpi harness, but it will be missing some wires i would need. be easy enough to splice it in, but if u have the ty/cy harness, it is all there.
