An engine control unit (ECU), also called an engine control module (ECM), [1] is a device which controls multiple systems of an internal combustion engine in a single unit. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
Oct 15, 2023 · ECU functions as a microcomputer controller, processing data from sensors, executing instructions, and enhancing vehicle performance and efficiency. It not only manages engine functions but also controls safety and transmission systems, contributing to overall vehicle safety and performance.
The engine control module basically controls the intersection of the engine's necessary ingredients to make energy — fuel, air and spark. What does the engine control module do? It constantly monitors a vast network of sensors around the car to ensure conditions are within normal operating range.

The term can be used to mean an Engine Control Unit or an Electronic Control Unit, both are control units but one denotes the specific use in an engine system. Also complete explanation for the function of an ECU and its history.
An Electronic Control Unit (ECU) is a specialized device embedded in a vehicle to manage its electronic systems. It processes data from various sensors and makes real-time decisions to control different aspects of the vehicle’s performance.
Modern cars’ Engine Control Units (ECU) rely largely on precise, real-time data from a wide range of sensors to function. These sensors take measurements of several factors that are crucial to engine efficiency and performance, including temperature, pressure, speed, and composition.
