Is It Necessary to Install an Electronic Throttle Response Controller?
1 Answers
Whether to install an electronic throttle response controller depends on the owner's usage needs. The electronic throttle response controller collects signals from the throttle pedal position sensor, reprocesses the throttle signal, and sends it to the ECU, thereby improving engine response performance. This enhances throttle sensitivity, accelerates starting speed, improves the vehicle's instantaneous acceleration performance, avoids sudden forward surges, and prevents engine carbon buildup. Characteristics of electronic throttle and cable throttle: The cable throttle system is simple and directly controlled, with a 1:1 ratio between the throttle pedal and throttle valve opening. In contrast, the electronic throttle system means the throttle pedal only reflects the driver's intention, while the final throttle valve control is handed over to the ECU. Working principle of the electronic throttle response controller: The so-called 'acceleration' is mainly achieved by increasing throttle response sensitivity, which amplifies the input throttle signal by 50%. At any time, the last 33% of the throttle signal is no longer useful. When the driver presses the pedal to 66%, the controller's output is already at full throttle, thereby increasing throttle response sensitivity by 50%. However, the electronic throttle response controller does not reduce the gradation of throttle signals as many claim. In reality, the throttle signal remains continuously adjustable, only changing from the previous 1:1 ratio to 1:1.x, where x is the signal amplification coefficient.
