Newer Acura vehicles monitor your driving habits and make adjustments to the throttle response, transmission shifting points to adjust to the driver habits. The problem with this system is that at times it decreases throttle response and shifting in a negative way. To reset the ECU and transmission on your newer Acura, follow the instructions below. This method will reset ECU and transmission to default factory values. It will not erase any settings other than user recorded data. If your Acura is not new, this method will not have any effect.

Turn the car off and restart it. There will be no confirmation or beep but at this point, the ECU and transmission have been reset. If you are not sure, repeat the procedure one more time.
