I just picked my truck up at the dealership after having it ECM re-flashed; and am curious if I put my Edge back in will it remove the update?

Thanks,

Al

the edge is just a piggy back system, therefor it does not "write" anything. It only modifies your stock ECU settings.

Therefore, if you have a new flash from ford, then the Edge will only modify your new ECU settings that ford flashed.
