How has electronic fuel injection made cars more efficient?

    Yes, the engine control unit or ECU controls the airflow and gas that enters into the fuel injection system which increases efficiency in different situations including when the car is idling or when the gas pedal is press with varying force. Additionally, as better fuel injection technology is created, including the nuanced “direct fuel injection” (see second link) the car’s overall efficiency can be increased 10-12%.
