I have a ls7 swapped into an FD rx7 using a modified vette harness and an 06 z06 E38 ECM. I am getting a P0315 code for the crank relearn. I have tried a million times to get the relearn to work unsuccessfully. I have searched the forum and read numerous suggestions on how to get it to work and I have tried everything people have suggested and it will not run.
I have brake input from my brake pedal switch, clutch input from my clutch switch, and in the logger i can see with key on they both function properly. When i try to do the learn procedure i get the error that it cannot be done with faults, which i dont have any besides the P0315. I tried disabling the P0315 code and that didnt work.
I see a lot of threads with similar issues but they never seem to have a proper resolution. I have several drivability issues that may or may not be a result of this issue.
Any ideas? I read people discussing parking brake input, but I don't see anything on the wiring diagrams or e38 pinouts that indicate parking brake signal is ever sent to the ecm
