The service manual specifically mentions the PCM needing to see the change in the signal of the brake pedal. I was surprised to see that the my 2000 Firehawk (with 12200411 PCM) DID NOT need to see a change in the state of the brake switch.

Could you further explain? Do you mean that I could somehow add this parameter to EFILive? This is how TunerCat OBDII displays the parameter. I would have expected to see this in the EFILive selection of parameters.




Latest Progress
Very little time to work with this engine. I did notice that the PCM recognizes second gear on the test stand. I'm going to have to play with the gear selector switch wires to figure out how to make the PCM see first gear. I think this may be the culprit. I may try again this week.
