Working on my 2000 C2500 5.7 (now 383). Ordered a tuned PCM and installed it today. It runs, no check engine light, but I understand doing a crankshaft position relearn is recommended.
I set the distributor offset to 0 (+/- 2) degrees @ 1000 rpm on the old PCM. Do I need to readjust this for the new PCM? And after performing a crank/CASE relearn, will this change the offset?
My scan tool can't do the relearn so I plan to take it to a shop tomorrow. But was wondering if these adjustments affect each other. If I would need to change the distributor setting before/after the crank procedure
