Drive-by-wire technology has plenty of advantages, but if there’s one place where many folks would prefer the feel of a taut steel cable, it’s throttle response.
That’s because on some vehicles, the electrons from the throttle position sensor seem to take the scenic route on their way to the throttle body—which often results in a lag in pedal response.
And that delay can be particularly annoying in performance applications.
So the folks at JMS Chip developed a simple PedalMAX Drive-by-Wire Booster Module that plugs in between the TPS and your vehicle’s main wiring harness. The module has a standalone rotary knob that you can install in the dash or tuck out of the way in, say, the glove compartment.
Once the PedalMAX is installed, you can quickly adjust pedal response in real time to fine-tune the perfect amount of “pedal feel” you’re looking for.
Now, these PedalMAX Boosters are application specific, so you’ll need to find the right one for your ride. But JMS makes modules for dozens of the most popular cars, trucks, and SUVs, so there’s a good chance they’ve got one for your vehicle.
Want to see how to install one? Check out the JMS PedalMAX at Summit Racing and not only will you be able to filter by specific vehicle application, you’ll find an example walkthrough video of a sample installation there too.
