Okay, so it is located on the driver's side of the car (facing the car)..: An electronic control unit contains the hardware and software (firmware). This process is often carried out at an engine performance facility. An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. For many models of vehicles you can find online repair services for between $300 and $400 for a complete repair or reprogram of the ECU. Programming an ECU typically requires interfacing the unit with a desktop or laptop computer; this interfacing is required so the programming computer can send complete engine tunings to the engine control unit as well as monitor the conditions of the engine in realtime. The mass air flow sensor measures the amount of air flowing into the engine through the throttle plate. Typical modifications that may require an ECU upgrade can include turbocharging, supercharging, or both, a naturally aspirated engine; fuel injection or spark plug upgrades, exhaust system modifications or upgrades, transmission upgrades, and so on. In most vehicles, the ECM is located in the engine compartment. Note:If you cann’t find your vehicle model below,check three locations: Beneath the wipers behind the plastic trim.
