What is ECU in car?

ECU stands for Electronic Control Unit, or in the language of mechanics, it is called "black box".

ECU is like a computer or "brain" to control the operation of almost all systems in the car.

ECU is a combination of electronic microchips and sub-components used to recognize signals, store information, calculate and send appropriate signals, and finally decide the vehicle's working functions in the most reasonable and effective way.

Modern cars are no longer controlled manually like the old generations. Today, sophisticated technology is being incorporated in the form of computer control to control and ensure the performance of the engine. Whenever you make a physical change to the car, the data related to that change is recorded in all the computer memories that control the car.

Currently, the ECU has a mechanism to control and govern all engine operations through receiving data from sensors on the car. Then the signal is transmitted to the ECU for processing and giving "commands" that force the actuators to perform such as: fuel regulation, ignition angle, camshaft angle, automatic throttle, braking force at each wheel...

ECU is capable of controlling all engine operations to provide the vehicle with stability, precision, optimization and safety. Components such as ignition, fuel pump, throttle, camshaft, or braking force... all comply with and always follow the decisions made by the ECU electronic controller.
