Located under the hood, the ECM is responsible for monitoring and controlling a variety of functions within the engine.

One of the key functions of the ECM is to regulate the air-fuel mixture for optimal combustion. By constantly monitoring sensors such as the oxygen sensor and mass airflow sensor, the ECM is able to adjust the fuel injectors to ensure the engine is running at peak efficiency. This not only improves fuel economy but also reduces emissions, making the Mustang GT more environmentally friendly.

In addition to managing the air-fuel mixture, the ECM also controls ignition timing, idle speed, and engine cooling. By adjusting these parameters as needed, the ECM is able to ensure smooth and reliable engine performance in a variety of driving conditions.

Furthermore, the ECM in the Mustang GT is equipped with diagnostic capabilities that allow it to detect and store any trouble codes that may indicate a problem with the engine. This information can then be accessed by a trained technician using a diagnostic scanner, making it easier to identify and address any issues before they escalate.

Overall, the engine control module in the 2021 Ford Mustang GT is a crucial component that helps to optimize engine performance, improve fuel efficiency, and ensure the vehicle runs smoothly for years to come. Its advanced technology and diagnostic capabilities make it an essential part of the Mustang GT's high-performance engine system.
