My "nucking futs" rubbermount, efi Sporty build

I might have missed it, but what did you remove from the harness that would make the computer have issues? I assume you have removed everything except the engine control/fuel management stuff. I am new to the cut down efi sportster wiring, but have had a efi swapped daily driver auto since 1994. I hope I can offer some magical cure. Not sure what issue you are having.
