ECUs, PCMs, and ECMs rely on sensors that monitor various parameters such as engine temperature, air intake, throttle position, and more. Based on the data collected from these sensors, the control modules adjust fuel delivery, ignition timing, and other parameters to optimize engine performance and efficiency. The Electronic Control Unit (ECU), Powertrain Control Module (PCM), and Engine Control Module (ECM) are essentially the brain of your car. They are responsible for overseeing and regul...
