It's not a bad thing. Get the new cable and see if it will open the tune. If not yes the ecu will have to be removed. They do not open it up. It only takes 10 minutes to remove on my rt. Have them get you a ship label if you go that far and they overnight it back to you. There has been other threads on this topic. Good luck. With monster if something goes wrong you have to send it back everytime. Dynojet tune can be returned to stock.
