The ECU is a microprocessor based computer that receives and evaluates readings from sensors located throughout the engine. The control unit then produces a control signal that is sent to the injectors so that the correct amount of fuel for any operating condition can be injected into the cylinders. Located in the right kick panel, it also controls the Constant Idle Speed system.
