An ECU, or Engine Control Unit, is essentially the brain of a car’s engine. It’s a small computer that constantly reads data from various sensors like airflow, oxygen levels, temperature, and throttle position, then uses that information to control critical functions such as fuel injection, ignition timing, air–fuel ratio, idle speed, emissions systems, and even turbo boost in cars that have one. Every time you press the gas pedal, the ECU is making hundreds of rapid decisions per second to keep the engine running smoothly, efficiently, and safely, which is also why people modify or “tune” the ECU to change performance, throttle response, or fuel economy 🚗⚙️
