PCM swap
It'* that time of year again. Well, not required, but it is in the works for another engine swap. For those with HPTuners, I really cannot find an answer to this...
Current setup is, 97 L36, upgrading to L67 from a 99 Buick.
Can I say, get a stock .bin file from another 97 L67 and program that on top of my L36 PCM? Or do I need to get a L67 PCM and update the VIN?
Another question is, if I initially use 2 credits to edit the current L36 PCM, will I lose another 2 credits if I do a change over? HPTuners credit system confuses the snot out of me.

The difference is only minor. No need for more credits. Get a BIN file from a L67, then do a compare with your L36 BIN. And simply make the changes. mostly it will be the timing table, injector table, MAF curve. Just go threw and make them match.
