I converted a TPI engine to use the 12200411 PCM with a modified Express Van calibration.
The engine started right up and threw the following (expected) codes:
I was unable to successfully perform the crank relearn procedure. I initially had a transmission code P1810 that was preventing the relearn procedure, but after disabling that code, I still can't perform the relearn. I can press the relearn button and see the countdown, but when I rev the engine it'll go beyond 5,000rpm and never cut out the injectors. I've disabled all codes that EFILive is saying will prevent the CKP relearn procedure. I'm stumped. Any suggestions?
