A kart's ECU box is like a smart computer for the engine. It constantly checks engine speed, temperature, and throttle position. The ECU adjusts how much fuel goes into the engine and when the spark plugs ignite, making sure everything runs smoothly. It also prevents the engine from revving too high to avoid damage.
