FYI- I have put over 5000 miles on the car with the old engine, and setup. It works, or should I say- worked with all the old wiring harness, ecu, biu, etc. Why would it not work now? The key, switch, etc are all from the orig. donor car and are matched. I did have a shut-down with the old engine during a torrential rainstorm- just absolutely died and had to tow the car home. A day later it started no problem. That issue was never diagnosed, as it never happened again. Could it be the same problem??? It had no fire then either.
If I go stand alone, will I lose ABS, OBDII potential, and emission compliance that I have now?
I am not sure if this will work- but I threw a few photos of the build:
