Crash course on OS
If the PCM took the calibration and it runs fine, what could the difference in OS be? How do I change the OS? Should I keep the current OS or change it to something else?
What year .bin was the one you received this error on?
I then went to the bin repository and "borrowed" a VIN for a '99 camaro.
Using that VIN, I downloaded the stock calibration from GM to overwrite the '00 sliverado calibration that was in the PCM, before I EVER hooked HP Tuners up to the PCM. The stock Z28 calibration loaded fine, and I have been modifying it with no problem, its just that when I tried to load the bin from the bin repository of the car I borrowed the VIN from, thats when I got the error.
So apparently, I'm running a '99 calibration on an '00 truck Operating System.
My questions are:
1) will this ever be a problem using it like this?
2) can I change it to the '99 Z OS or is my HP Tuner locked to the '00 OS?
However, if the OS ID for your 99 .bin is different from that of the .bin you download it won't work doing just a calibration (quick) write...
