Yup - I could not get the JB4 to delete code until the car was stopped and in diagnosis mode. To do this hit the stop/start 3 times fast and this will place the car into diagnosis mode.

To your point this product was a money grab when it comes to this car. No real development has been done. Why would I receive a harness with EWG connections when clearly this has not been sorted out? The user interface still says F chassis and to me it I feel no real thought was placed into this for the G chassis.

I should have gone with racechip. Would have received a guaranteed 60hp and those guys spent weeks designing and testing a solution for this car.
