I've seen it both ways, is it a p01(red/blue) or p59(blue/green)?

ok, I look forward to it. Keep in mind, around those years GM developed new OS numbers to show that a car had been to the dealership although the OS and calibration was identical :thumbsup:

Hi kur4o,
I have all my files by year, then make/model. It would be a huge amount of work for me to convert it to OS numbers. What year/make/model is that OS used?

I have no history with this bin file, just one in my archives. Hope it works for you :)
