All you have to do is figure where in the ram the routine is loaded and if some of the stuff is overwritten.

Gm even assigns them a part number, so you can make a list based on car, model, pcm used.
I compare two flash routines for 1mb pcm and it was 1 byte difference/2004 y-body vs 2005 truck/. It could be intel vs amd flash.
Does intel /amd pcm have different hardware part numbers.
That's very interesting.....I it might be outside the scope of this thread currently so I'm going to PM you about this until I know exactly how/if this would be useful for what we are working on.
