I'm talking about hardware, does the PCM hardware change at all through the years?
I know 98 PCM Binaries have 1 checksum I believe and 99+ are broken up into 8...
However, if the hardware is the same, in theory a 98 PCM should be able to take a 00 flash no problem and a 01 PCM should be able to take a 98 flash no problem..
I'll be picking up a Spare LS1 PCM and want to do some testing.
