I wonder if anyone has access to info on GM specific OBDII PID codes. I
am interested in as many as I can get my hands on as they all point at
specific routines and locations within the ECM. I can share the
locations when complete. In any case, here is a list of the supported
PIDs. I expect one of these (or several) is used to flash the ECM.
