    Disconnect battery after a new PCM Flash Tune?

    Hi,

    Is it recommended to disconnect the battery after flashing the PCM with a new tune, then going out to put some miles on it before data logging for the next tune? What are the pros and cons.. Is it really needed like the Airaid? I'm tuning a completely stock setup with no Airaid.

    I would to allow it to erase all of the driving habit parameters it's likely stored just to be safe. If you're gonna do some logging might as well do it fresh.
