Not sure what all info is useful, but here's basically everything about this one. Vehicle info pulled from the VIN number provided by PCM Hammer. I can also validate the read over BDM, test write and repeat the process. Might take me a bit to get the BDM setup though, it's around 2am in the usa atm so might head to bed lol.
I have 10 of these computers, all slightly different serv numbers and codes. I can post them all if that's useful. I didn't realize these were 3.8L computers, but not a big deal, I have a stock 3.1L bin I should be able to dump on it, pretty sure it was the same flash chip if I recall correctly.
Btw this was done with a bench harness I built (all brand new everything). Program says my connection is great, that's kinda funny but makes sense
. I know these computers can be super sensitive on the BDM side of things so it sounds like it's sensitive on the OBD2 side too.
