Bill, I read a tsb stating sps would no longer overwrite the same calibration to a module because dealerships were bricking modules that way. Sometimes writes would fail and gm didn't want ( shouldn't need) to replace a module if they weren't updating to a newer calibration.

Cinncinatus, I recall hearing/reading something similar but I have yet to experience a module that both SPS/SPS2 would not reprogram with the same file on non-global A vehicles. Experiences may vary however and things may change in time, but for now, all I get is the message box and I click "OK" and go ahead with the reprogramming. I have tested this on the bench however, not in-vehicle, so that may be the key to the issue ending in possible paperweight status.
