Drive-by-wire accelerator pedals have become the standard in OEM automotive applications. Rather than having the traditional throttle cable running up from the pedal to the carburetor or throttle body, modern vehicles use a pedal position sensor that tells the engine computer how far down the go pedal is being pressed.
The benefit is compact packaging and the fact that throttle body and throttle pedal don’t have to be in close proximity to each other because they’re not mechanically linked. One disadvantage, however, can be a mushy pedal feel with lagging throttle response.
Amp’d can help fix both of those issues with their 2.0 Throttle Booster. Available for a number of Dodge, Chrysler, and Jeep applications from 2004 and up, it’s a completely standalone unit that’s plug-and-play. “It takes the factory accelerator signal and remaps the sensitivity, reducing the delay for better throttle response and more on-demand power,” says Holley’s Jeremy Stoermer.
A wireless switch comes preloaded with five different levels along with three slots for custom configurations. The Amp’d app makes it easy for users to construct their own maps for just the right feel on their right foot.
Installation is simple as the module plugs right in to the factory pedal position sensor harness. From there, a smart phone can basically take care of the rest of the setup and tuning. It only takes a few minutes, but the payoff is an accelerator that actually comes alive when you want it to.
