Flashed = updated. (In the computer world writing data to an eprom is called "flashing" the chip.) When you tune you update the ECM with new settings. So if your car has original factory tune it would show a "1" (It might be "0" I am not sure the counter but it has a starting number). You get an aftermarket tune the counter would go to "2". You then flash back to stock the counter would be "3". Even though the tune would be stock the dealer and GM would know that it had been flashed. This would VOID your powertrain warranty as flashing the ECM is not allow except by the authorized GM facilities (aka Dealers).
