It's a piggyback tune not an ecu flash tune. The old Dinan tunes would flash the ECU, but that was 2 generations of car ago. Dealer can't reprogram the Dinan tune and many have taken their cars in with other piggybacks and not had issues with software updates, so don't know why this would be any different, dealer probably not too knowledgeable. |
That was just last gen, the e9x had a flash tune from dinan
