PCM Relearn Does anybody know what items are affected when the PCM is doing a relearn? I know there is something to do with the idle (not final RPM) and maybe some other items.

Re: PCM Relearn Well, I'm pretty sure that the LTERM FUEL TRIM values for Bank1 and Bank2 are saved in memory during the learn process. I believe that the short term fuel trims are reset back to zero when the ignition is turned off.
It is possible that something related to knock learn is also kept long term.
