think you mean re map your ecu? yes no?

make model age?

then someone will help

probably a good idea getting a re map or checked on the rollers. if its the car in your pics. you can re map the standard ecu on your car.

someone will correct me if im wrong.

To reset ECU = erase its memory of the bad habits it has learned, disconnect battery, press brake pedal, reconnect battery, drive car gently till warm (or 6 miles minimum) then boot it. But this does not equal a re-map.
