Thanks guys. I did the resistor trick with my tpi motor so that's no problem, just get the key that went to the donor.
How about tranny swaps. If I find a '95 that came with an auto and I want to put a T56 behind it can the ecu be reprogrammed to ignor the park/neutral switch?
I have this problem with my tpi. I have left the the P/N wire open/ungrounded, but when the motor is cold, before going into closed loop, the idle hunts. I'm not certain it's because of the P/N wire, just suspicious. It isn't that bad, maybe 200-400 rpm, and it doesn't last long, just annoying.
