Did some more hunting around tonight in the ECM-There is no pin currently connected to the exterior of the ECM that is tied to Pin 60/AN4 of the E-side 'HC11. A LOT of pins have 5.6K or 9K resistance to that pin, though, which reaffirms my suspicion that it's grounded-as all unused analog input pins should be for good practice.

I don't have any method of currently flashing the PCM right now, haven't bought Winflash because to be honest, I don't really trust the TunerCATS website, and I don't have 50$ to drop on the Madtuner software right now. As soon as I do, I'll lift the AN4 pin on the auto ECM and see if I can twiddle the line, is there any indicator in Tunerpro that would tell me if I have the right pin?
