Crank Relearn scanners???
#32
The only reason you should need a relearn is if the motor was started with out the stock pcm, or if you called up jesse and had him send you a new one while you drove around on your stock pcm. The pcm remembers the last crankshaft position and if it moves or changes without the pcm knowing about it you will need the relearn.
