Does not look like there is an XDF for mine.
I tried to look at my bin in flexhex but it appears the ANSI pane is in Chinese language?

Would it be possible to reflash your PCM with a .bin file that has a .xdf file? Maybe a 2001 or 2002 LM7 .bin file?

I need to research what os's mine supports
GM made the following changes from the original 9363996 OS
9363996 N/A Operating system
9365637 N/A Change required to reduce rich fueling during tip-in.
9373372 N/A Calibration change required to correct an IAC reset error
9379910 N/A New software to engage A/C during engine crank to prevent A/C belt damage. Also enhanced park/neutral diagnostics.
I cannot find XDFs for those OS's either
I just need to figure out what os that has an XDF will run on my hardware. I have been trying to figure it out with weeks of searching

I'm not sure if starting over with a newer / different PCM makes sense or not. Perhaps purchasing a PCM that is flashed with an OS you can work with is an option?

For example: Flash Masters (an ebay seller) https://www.ebay.com/itm/17340783457...QAAOSw3v5YqKyg

The wiring for "Stand-Alone" 99-00 vs. 01-02 computers are the same, or perhaps a couple wires might need to swapped?
