ECU

An ECU, or Engine Control Unit, is a small computer that manages and monitors your vehicle's engine. It collects data from different sensors—like temperature, airflow, and engine speed—to ensure the engine runs efficiently and smoothly. The ECU adjusts fuel injection, ignition timing, and other functions in real-time to optimize performance, fuel economy, and emissions. Think of it as the vehicle’s brain, constantly processing information and making decisions to keep the engine operating at its best. Advanced ECUs are essential for modern vehicles, integrating with other systems for enhanced safety and functionality.
