Part Deux is absolutely correct, if brief. The PCM's flash memory is only modified when a new program is flashed in. This is done either by the dealership with a StarScan device or with a custom programmer such as the DiabloSport Predator.
On the other hand, learned adaptives are stored in volatile memory that is not flash memory, and is lost when you drop battery power. That's what you want.
Now, it's entirely possible you might benefit from a flash to a newer PCM code for other reasons, but for what's stated... no.
