Problems with CKP relearn on 2001 12200411 PCM

[ChipsByAl]

To perform the crank variation learn procedure with the Tech2, the brake pedal needs to be pressed. It may need to see the change as well, but I am not sure. I haven't used EFI live to do the learn yet so I can't comment on that. In either case I would try to simulate the switch. Disabling the brake switch or P/N codes doesn't change the PCM's "mind."

As far as the PRNDL switch wiring not being on the F-car, I wouldn't concern myself about that. The Camaro does not have the display in the cluster, it is on the shifter and moves with the lever only. The function of this switch could be added to EFI_Live to be enabled or disabled.

To perform the crank variation learn procedure with the Tech2, the brake pedal needs to be pressed. It may need to see the change as well, but I am not sure.

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.

The function of this switch could be added to EFI_Live to be enabled or disabled.

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.
