Upgrade the throttle response of your Mercedes-Benz, Freightliner Sprinter, or Smart with the Pedal Commander PC43 Bluetooth Throttle Response Controller. Engineered as a direct plug-and-play upgrade for a wide range of Mercedes-Benz C-Class, E-Class, GLE, GLS, CLS, SL, and Sprinter Van models, the PC43 eliminates factory drive-by-wire throttle lag to deliver quicker, more responsive acceleration without modifying the ECU or increasing horsepower.
Modern drive-by-wire throttle systems are programmed with built-in throttle lag that can make acceleration feel sluggish. Pedal Commander removes that delay by optimizing the accelerator pedal signal sent to the ECU, providing immediate throttle response while maintaining all factory engine safety features. Bluetooth connectivity allows you to control settings from your smartphone, while four driving modes and 36 total sensitivity levels let you fine-tune throttle response for daily driving, spirited performance, or improved fuel economy. Installation takes approximately 10–15 minutes using vehicle-specific connectors with no cutting, splicing, or permanent modifications required.
