Ok so my buyer is here to pick up the car and we decided to port my completed tunes over to his HPT by uploading them onto the PCM with my DHP then downloading and saving them with his HPT. Looong story short, a series of bad decisions led to bricking the PCM in the car with the new owner 1500 miles away from home. is the deal with the compatibility between OSIDs, VIN's, service numbers etc. I have a 1998 Regal GS PCM that I have always considered my "spare". For situations like this and we tried to upload my .bin and vin to it and it wouldn't go. Just says osid is not compatible with PCM. Tried to import all the changes from the tuned .bin to the stock GS .bin and upload that back to the GS PCM and the car won't start.
Everything I've read says oh they are all interchangeable between 1998 and 2002 but we tried everything from turning security functions and dtcs off to resetting the vats, trying to match VIN numbers in files. No matter what we did it would not start. My regal GS PCM should be a 16236757 my stock 99 PCM should be a 09361735. Now that it is totally ****ed WHAT DO WE NEED TO BUY to upload my completed 1999 GTP .bin file back onto a PCM and get him on his way with the car?
