Where can I find the serial number info in my obdii gm pcm?
Also how hard would it be to alter crank resolution in the pcm programming or can it even be done?
I'm not real good at the programming level stuff,hoping someone can enlighten me.
I think if I knew the address location for the info I could check it out furthur in the .bin .
I'm sure that info is in the SAE papers but I can't find access to them either.
If it is specific to a certain pcm then i'll say for a 12200411.
