I will try to make this short . I thi k i know the answer but will ask any way . Daughters car was damaged when car was srruck by a deer at freeway speeds . Left side damage ,they say the ecm needs replaced . Car had a Cobb tune ,unknown any more than that , and she does not have the hand held . Will the dealer be able to extract the Cobb tune and flash it to the new ecm ? I personally think they are feeding her a load of poop. Car drove home from the crash scene and to the dealer under its own power . My belief is , no tuner , no way to recreate the tune in the new ecm .
