What is the primary function of the Engine Control Unit (ECU) in a vehicle?

The primary function of the Engine Control Unit (ECU) in a vehicle is to manage various engine functions and optimize performance. One of its critical roles is to transmit operation information to the vehicle's driver, typically in the form of data displayed on the dashboard or cockpit area like speed, fuel levels, and engine diagnostics. This helps the driver understand the vehicle's status and any potential issues that may arise.

In addition, the ECU also adjusts fuel injection, monitors engine parameters, and regulates the timing of engine operations, which indirectly relates back to its role in providing crucial information about the vehicle's functioning. Therefore, its connection with the cockpit is essential as it ensures that drivers receive real-time information necessary for safe and efficient vehicle operation.
