Pedal Commander throttle response controller connects to the BMW 5 Series’s throttle pedal assembly to intercept the drive-by-wire throttle signal. It amplifies the signal to eliminate throttle lag and make the throttle reaction more aggressive. You can customize the throttle response with Pedal Commander’s 4 modes (Eco, City, Sport, and Sport+) and 36 individual settings for precise optimization for your driving style and needs.
