An electronic throttle controller is a throttle response controller that helps reduce response delays in your electronic accelerator pedal. It allows your engine to respond more quickly, resulting in faster acceleration. Acceleration principle: By adjusting the valve reaction efficiency, the throttle becomes more responsive, increases reaction speed, and enables quicker starts. Provides improved driving performance without affecting original vehicle functions or damaging the engine.
