Open Loop VS Closed Loop

Open Loop VS Closed Loop Open-loop and closed-loop are two different modes of operation for engine control systems, particularly fuel injection systems. They describe how the engine control unit (ECU) adjusts fuel delivery based on feedback from sensors. Open Loop You can often find open loop and closed loop maps inside our TunerPro XDF definitions…
