Corvette CCM Reverse Engineering Anyone?

I think if you could help us locate the location of the reman pin register that would be awesome. For the 94-96 units you determined it was at $644b bit 2. There are a few rom dumps staring around post 411 of this thread.

Then maybe we can build a list of PROMIDs to determine where to look to see if the reman pin is in the correct state for unlock.

I'm still working through testing with and without the VATS options on and off in my PCM tune (@ $2028 and $12017). There's definitely something to this because with it enabled there's no way to get the CCM to shutup without the correct passkey resistor.
