I'm sure we can find a tuner (independant source, might have to pay a bit though) here who can view the ECM and see if any permanent modifications were made. Simply viewing the ECM settings will not increment the flash counter. The only problem I see with that is this device will cut into their business since part of a tune is generally to turn off AFM.
The best way to do this is take a car that has driven with the Range device (but has never been flashed with a tune) to a dealer. Tell them that you'd like to buy the car, but want to see if it's ever been reflashed by something other than the dealer diagnostic tool.
