It takes more than 30 seconds to relearn idle.

If you disconnect the PCM to reset the PCM Codes, and the idle quality,
you leave the PCM disconnected for a minimum of 5 minutes.

It takes 2 - 3 drive cycles to relearn idle quality.

To reset the Transmission Shift Patterns, you need to leave the PCM disconnected for a minimum of 20 minutes.

This takes a couple of days to relearn shift patterns, since the shift patterns are tailored
to the driving habits that the vehicle is subjected to.
