An ECU (Engine Control Unit) controls engine performance via a series of actuators (that move and control engine mechanisms) on an internal combustion engine. An ECU interprets data from a series of sensors within the engine bay and accordingly adjusting the actuators.

Why Do I Need an ECU?

The ECU in your vehicle has several jobs, fom controlling the engine to rolling up windows, and is a vital component to any car - you can think of it as the computer inside your car! Some major roles of the ECU are control of the air-fuel ratio, control of idle speed, control of variable valve timing, and electronic valve control.
