Ultimate9 evcX Throttle Controller (Chevrolet Silverado 2019+ 4th Gen)

The Ultimate9 evcX Throttle Controller for the Chevrolet Silverado 4th Gen (2019+) changes how your Silverado’s accelerator pedal talks to the engine. It cuts the lag you feel on take-off and lets you tune throttle response to how you’re driving. You can sharpen it for towing heavy vans, boats and trailers, or soften it for smooth control off-road and in traffic. You adjust it all from your phone, and it plugs straight into your Silverado’s pedal in about 15 minutes.

Key Features:

Cuts throttle lag for quicker, more responsive take-offs in your Silverado

8 driving modes and 32 levels of adjustment

Ultimate and Ultimate9 modes for sharper response when towing heavy loads or overtaking

Eco and Anti-Slip modes give smooth control off-road, for low-speed towing and reversing, and on slippery surfaces

Launch Mode for controlled take-offs with less wheel spin

Valet and Factory modes for parking or handing over the keys

Lock Mode blocks all throttle input to immobilise your Silverado for extra security

Wireless control through the Ultimate9 TC app (iOS and Android), with no mobile data or Wi-Fi needed

Compact, removable OLED display that dims itself at night, with dual USB-C ports

100% plug and play: fits in-line at the Silverado throttle pedal with no tools or modifications

Vehicle Compatibility:

Chevrolet Silverado 4th Gen (2019+)

Please Note:

A throttle controller changes pedal response only. It doesn’t add horsepower or change your engine tune.
