Yes it makes sence that the licence attaches to the pcms serial number, if i want the tune within it i will read it like you say and save it and just reflash but the operating systems have to be the same , and if i understand correctly i can not just simply program the calibrations and not do a complete flash with calibrations and operating systems because thoes tunning files were taken from a different pcm so it is a complete flash with operating systems or nothing , so if the operating systems are not identical in numbers i can not do it , it would be possible to compare files and to modify all tunning sections manually but that would take long i guess but do able , am i on the right track with all this , thanks alot Joe Eric
Eric,
If your new PCM has a different OS than your old PCM, then you want to copy the changed (by the tuner) tables from the new file to the old file, and do a cal only flash from your old file to the old PCM.
Hopefully your tuner flashed the new PCM with the same OS as your old PCM, in which case you can cal only flash the new file to the old PCM.
Or, if you want to update to a later OS, then you may have to copy tables.
Remind me which vehicle/year/model you have...?
Cheers
Joe

Nice to here back from you Joe, have a question , my friend just bought a 98 pickup with a 5.7 vortec, what could i do to the engine tune to get more power out of this , is it worth it because i am not familliar with these motors , he just installed a cat back with an air intake and he removed his cats , funny no trouble code because he does have sensors down stream from his cats that he removed , the transmission is a 4l60e , same as mine so that is not a problem , any advice , thanks Joe Eric
