New PCM

Replaced my PCM today seems the idle is a tad low. How long does it take for the PCM to learn the new components? Thank you.

When I replaced my PCM it ran rough for 15-20 seconds and then it smoothed out has been fine ever since.......
If you haven't done this, you may want to clean the Idle Air Control sensor
