Sensors: The ECU collects data from sensors like the oxygen sensor, mass airflow sensor, and throttle position sensor to monitor the engine's condition. Calculations: Using the input from sensors, the ECU calculates the ideal air-fuel mixture, spark timing, and other parameters to maximize engine performance. Output: The ECU sends signals to various components, such as the fuel injectors and ignition coils, to make adjustments based on the data received. Why is maintaining your ECU impor...
