What unit controls the fuel injectors?

The Engine Control Unit (ECU) controls the fuel injectors.

Here's how it works:

* Sensors: The ECU receives information from various sensors like the oxygen sensor, throttle position sensor, and engine speed sensor.

* Data Processing: The ECU uses this data to determine the optimal fuel injection timing and duration for each cylinder.

* Fuel Injector Activation: The ECU sends electrical signals to the fuel injectors, which open and close to deliver the precise amount of fuel needed for combustion.

Therefore, the ECU acts as the "brain" of the fuel injection system, making decisions about how much fuel to inject and when to inject it.
