Pedal Commander is a throttle response controller that removes response delays on any vehicle with an electronic gas pedal (most vehicles made after 2005). This is achieved by amplifying the signal being sent from the sensor on your gas pedal to the vehicle's ECU (computer). Today’s newer vehicles lack the responsiveness that came with older throttle cables. It doesn’t matter how fast you push your gas pedal to the floor, you don’t have access to all the power your vehicle has to offer. We are your solution! One of our most frequently asked questions is “how much horsepower does it add?” Pedal Commander doesn’t add any horsepower, but it does let you use the existing horsepower of your engine by allowing you to access it quicker with the amplified signal. This performance increase cannot be achieved with your typical aftermarket tune or programmer. Pedal Commander is the only device that lets YOU choose how you want your throttle to respond and change it on the fly. There are 4 different modes, with 9 sensitivity levels for each mode. This gives you a total of 36 levels of response to choose from, ensuring there is something for every driver in every vehicle. While there may not be anything else out there like it, Pedal Commander is completely compatible with any other aftermarket parts you may already have. And since we don’t use the OBDII port, this means it’s a perfect match to compliment your existing tune or programmer to maximize your driving experience. Undetectable by dealerships, won't void a maintenance plan! We understand not wanting to risk voiding the maintenance program on a new vehicle, but that no longer means you have to wait 5 years/50,000 miles before you can start customizing your car or truck to drive how you want it to. When a dealership does any kind of work or repair, they run a scan on the vehicle's computer to see if anything has been changed. Other aftermarket tuners and programmers will leave "flags" on the ECU after they've been installed, and will remain even after they've been removed. These digital footprints are what cause the dealership to void any kind of claim or maintenance program. Pedal Commander is 100% UNTRACEABLE by dealerships. Before going in for service, just make sure you turn the unit off and tuck it out of sight and you're good to go! You can leave it plugged in, no need to un-install or re-install, and they'll never know it was there.
