The Pedal Commander is a little device that connects to your car's computer. It lets you adjust how sensitive your gas pedal is. So, if you want your car to go faster when you press the gas, you can change the setting with the Pedal Commander to make it more responsive. It's like customizing your car to feel just the way you like it.
If you are looking to improve your overall driving enjoyment or reduce your eco-footprint, you need a Pedal Commander. Most newer vehicles are manufactured with Electronic Throttle Control (Drive By Wire). This means your acceleration is no longer powered with the old school throttle cable that gave you a linear relationship between your foot and the throttle body, but now everything is powered by electronics and your car’s computer (ECU). The electronic throttle does not provide the same performance as it creates a lag from your initial accelerator push.
