exactly what is a "crankcase relearn"? and what would cause the need for one?

Basically anytime the pcm is reflashed it needs to relearn its timing. It does that by watching the timing indicators on the crank pulley.

That's my understanding of it. Hopefully someone else will chime in and specify more clearly than me.
