    Video Review & Installation

    So if you own a 2008 F-150 and you wanna make your truck feel noticeably faster but you don't actually want to turn any wrenches and you don't wanna actually install any power-adding modifications, then the JMS PedalMAX throttle enhancement device should be at the top of your list. The way this device works is pretty cool. So I have to give you a little explanation about how your truck actually works when you press the gas. What happens is when you press the gas pedal, you're actually sending an electrical signal to the ECU. The ECU determines your pedal position and it makes a couple of computations before it opens the throttle body and adds air and fuel to the engine. There is a natural delay in this process. What the JMS does is it boosts that signal and it removes that delay entirely. Sounds pretty simple but honestly, it really does make a big difference. You'll definitely hear about it if you read the customer reviews. Installing this is also very straightforward and it doesn't actually interfere with any existing modifications and if you wanted to tune your truck in addition with the JMS, you actually could do so as well. If I had to give this an install rating, I'm going to give it a very soft one out of three wrenches on my difficulty meter. You don't actually need any tools to install this device and it shouldn't take you more than 10 minutes so I'll go ahead and show you guys how to hook this up real quick. So getting the JMS installed is pretty straightforward. The first thing you have to do is actually connect the device to the 20 pin connection and they do provide you with a tiny little flat head screwdriver to get these cute little screws tightened down. Once you've done that, it's really simple, all you gotta do is crawl beneath your dash here underneath the steering column, disconnect that little plug that you can find above the gas pedal. Once you've done that, you can go ahead and plug the black end of this connector here into that same location and then you're gonna connect to this grey connection into the wiring harness that you just unplugged. If you do want to use the desensitizing plug in the kit to drop this down from 100% to 60%, you can go ahead and plug that into this little connection before you do all of this. All right. So once you've got the PedalMAX plugged in, that's basically it. It'll be at 100% sensitivity by default. Again, if you feel that that's too much, and it may very well be if you've read some of the reviews, then you can plug in that little four-pin desensitizing connection even still. It's also a good time to use the zip ties in order to secure the PedalMAX underneath the dash, that way it's not flying around and you're not smacking it with your foot. If you want to be creative like us, we actually used double-sided tape. One other thing to point out, at this time, you can also plug in the little control knob which will allow you to dial in the sensitivity from 0 to 100. It's the same process, plug in that four-pin connection. You can actually secure it anywhere on the dash and again, go ahead and secure the extra cable with the zip ties in the kit. That wraps up this install. As you can see, pretty straightforward and you get to enjoy a throttle that honestly feels the way it should have from the factory.

    Description

    Eliminate Pedal Lag. If you're driving around town in your F-150 and have noticed a delay in throttle response between the time you step on the gas pedal and accelerate, that is due to the modern Electronic Throttle Control (ETC) Technology, which is also known as Drive-By-Wire. The gas pedal is controlled electronically by sending a signal from the pedal to the ECU, which then sends the signal to the throttle body, which results in that delay. JMS has the perfect solution to get rid of that issue with their PedalMAX Drive By Wire Throttle Enhancement Device. The PedalMAX is designed to eliminate the annoying delay by enhancing the signal between the pedal, ECU and throttle body to make it more sensitive and improve your driving experience.

    Improves Power and Improves Power.
    The JMS PedalMAX will not only eliminate pedal lag, but it will also enhance the throttle response, horsepower and torque in the low to mid RPM range. The PedalMAX is also ideal for eliminating stalling when accelerating from a stop in manual equipped F-150s.

    Maximum Throttle Response.
    Out of the box, the PedalMAX Throttle Enhancer is preset to provide maximum increase in throttle response. If you find the stock setting to be too aggressive for your driving needs, you can insert the supplied 4-pin RED de-sensitizing plug into the device. The RED de-sensitizing plug will reset throttle response to about 60% of the maximum setting. However, with the optional Remote Throttle Control Knob (part# BX-6999) you can adjust throttle response from 0% to 100% on the fly to match your specific driving style.

    Stackable. The JMS PedalMAX can be stacked or used in conjunction with other aftermarket OBD-II programmers and monitors. It is compatible with products from manufacturers such as SCT, DiabloSport, Edge, Superchips, Bully Dog, and Hypertech.

    Modern Electronics.
    The PedalMAX Drive By Wire Throttle Enhancement Device features JMS's exclusive state of the art digital technology housed in a proprietary sealed enclosure. The PedalMAX comes complete with plug and play wiring harness using OEM connectors for a quick installation.

    Easy Plug & Play Installation. The PedalMAX Throttle Enhancement Device simply connects to the factory stock pedal position sensor using an OEM style connector with no permanent modifications required. PedalMAX is 100% reversible making it warranty friendly.

    Application. This JMS PedalMAX Drive By Wire Throttle Enhancement Device is designed for use on all 2008 F-150s.

    Application Note.
    Some early 2009 F-150 models may have a plug that is the same as the 2008 model years. If you do, then you will need this JMS PedalMAX Drive By Wire Throttle Enhancement Device part# PX-5000-0510F.
