EFILive keeps multiple copies of the calibration in memory and whenever the EFILive software updates the calibration data it updates the copies as well. If any copy becomes different from the other(s) then this error is displayed. The only way for one copy to be different is if that copy was modified by some other application or bug/failure of EFILive or Windows or the PC hardware itself. Make sure you're using the latest update of the EFILive software (to eliminate the "bug in EFILive" possibility).

Has your PC been behaving strangely? Crashing or rebooting for no apparent reason? Applications freezing up or just terminating? Unexplained error messages? Features that sometimes don't work like copy/paste? Any of those symptoms could indicate some form of malicous code running on your PC. Or it could be a hardware/memory fault.

No, I get this message on all allison TCM's. It just depends on the day whether it acts up. My computer is acting fine. It seems to be when I try to change an entire table to a single value. Say for example I am trying to right a TCM tune for a DYNO and I want the truck to be in 4th gear the majority of the time. I go to the 3-4 shift WOT and Part Throttle tables and click on the upper left hand grey square to highlight all of the square to change them at the same time to say 20mph, the next time I go to save this tune is when I get the calibration change not made by EFI Live. If I go back to the original tune and make 1 change at a time and save as I go, it seems to be Okay with the changes. It has to do with changing multiple tabels at the same time.
