You will need to change your park/neutral rpm limits in the tune. When the ECM doesn’t see a transmission via canbus network, it eternally believes you are in park or neutral. This is not the case if the engine is tuned for a manual transmission. Change your rpm limits in the tune and you should be good to go.
