Review & Installation Video

Hey, everybody, I'm Justin with americanmuscle.com, and this is my detailed review of the JMS PedalMAX throttle enhancement device available for your 2011 and newer GT V6 and EcoBoost Mustang. In this video, I'll talk about some of the benefits of installing the JMS PedalMax on your S197 or your S550 Mustang and we'll touch on the install itself. And right up front, guys, I'm gonna tell you this is a plug and play job. One out of three wrenches on the difficulty meter but we will have a little bit more detail coming up later on. The JMS PedalMAX is going to appeal to the S197 and S550 owners out there looking to eliminate that annoying throttle lag that can sometimes be a little problematic with the newer drive by wire cars. Now, this thing can be used with or without your favorite custom tune and JMS even claims a little bump in low-end power and torque. But I don't want you guys to get hung up on power numbers because that's really not what the JMS is all about. So with all that said, let's take a closer look at this product. Now the days of having a cable-controlled throttle body are unfortunately a thing of the past. I'm gonna probably sound like an old guy here but I personally prefer having a cable-controlled throttle body to the newer drive by wire technology because I know the moment my foot hits the floor that throttle body will be wide open. With the newer drive by wire cars, the moment your foot hits the floor a signal gets sent to a computer, the computer tells the throttle body to open. Obviously, all this stuff happens very quickly but if you have driven the newer drive by wire cars, you probably noticed the smallest bit of lag in between shifts, especially when you're really rolling gears. And that's where the JMS comes in. Now most of the drive by wire cars are set up or pre-programmed from the factory for the masses. So this means driveability comes first, performance takes a back seat to that. Unfortunately for a lot of us Mustang owners, performance usually takes top priority and the lazy factory throttle can sometimes get in the way of that. So what the JMS is gonna do for you is monitor that throttle signal in real time from your drive by wire setup and then reprogram or remap that throttle signal giving you enhanced throttle response in the process. JMS actually claims that this is going to make the car more manageable in heavy traffic situations or stop and go type situations where stalling can be an issue. This is even gonna help modern Shelby cars which I have heard through the grapevine can be a little difficult to drive for newer owners out there. Stalling can be an issue. JMS claims this really helps out the modern Shelby owners. Again, I can't attest to that personally as I don't daily a Shelby. So the JMS is gonna monitor that throttle signal in real time from your drive by wire application, reprogram it or remap it on the fly, giving you increased throttle response in the process. JMS actually claims that this is gonna help make your car more manageable in heavy traffic situations or stop and go type situations where stalling can sometimes be an issue. Right out of the box, the JMS is gonna give you maximum effectiveness or maximum throttle response the moment you plug this thing in. Now for whatever reason, it's a little too radical for you or maybe it's a little too touchy for your driving style, you can always plug in the included the red 4-pin connector which JMS claims will desensitize this thing by about 40%. So you are still picking up a good amount of throttle response over your factory calibration but the car shouldn't be as touchy. So in essence, you're getting two standard settings with the JMS right out of the box as this product sits right here. However, if you did wanna have the ability to kinda fine-tune your throttle experience using the JMS PedalMAX check out their optional control knob here on the site for another 50 bucks. It does give you a few more settings to play with, and it does give you the ability to kinda change this stuff up on the fly. Now that's something that's not exactly easy with the JMS as it sits right now because you'd have to crawl under the dash, either plug in or unplug that 4-pin connector we just talked about. Not exactly something you can do while at a red light or while on the road. Now as far as using this thing with or without a custom tune, that's entirely up to you. But what I will say is the JMS PedalMAX here will give you some of the benefits of going with an aftermarket tune but without having to flash the car. So for you owners out there who aren't ready to pull the trigger on a tune just yet, this would be a great way to give you some of those benefits with saving you some money in the long run. On the other hand, if you did wanna piggyback this on top of one of your canned tunes that you already have or maybe even a custom tune, that's something you can totally do as well. In fact, check out some of our customer reviews if you haven't done so already. A lot of our customers have actually done this with great success. Just check those things out for yourself. As far as price or value, the JMS will set you back just south of 300 bucks which I admit isn't the cheapest modification for your S197 or S550 but it's certainly more affordable than some of your custom tuning options out there. Now sure, you're not gonna be getting the big power gains from the JMS like you would with those custom tunes but there are still certainly benefits to be had with the JMS. Moving on to the install and honestly, like I said earlier, it doesn't get much easier than this. Simple plug and play job with the JMS, maybe a few minutes from start to finish. And you really don't need a ton of tools to get this one knocked out. JMS does recommend unplugging or disconnecting your negative battery terminal first before getting started with the install. After that simply climb under the dash, remove the plug connected to the top of the gas pedal. After that simply plug in the JMS to that sensor there, plug in the factory harness to the JMS, and your install is complete. So that's my review of the JMS PedalMAX for your '11 to '17 Mustang which you can get right here at americanmuscle.com.

Eliminates Pedal Lag. The drive by wire accelerator pedal of the 2011 to 2017 Mustang is well known for lag. If you have ever tried to speed up to merge with traffic you have most likely noticed a delay in throttle response. On older Mustangs the gas pedal was attached to a mechanical cable that ran to the throttle body or carburetor that provided instant feedback. However, on modern Mustangs the gas pedal is electronically controlled, similar to a dimmer switch, which has to send the signal to the ECU, which in turn sends the signal to the throttle body causing this momentary delay. To eliminate this annoying delay JMS created their PedalMAX Electronic Throttle Enhancement Device.

Eliminates Stalling and Improves Power. The JMS PedalMAX will not only eliminate pedal lag, but it will also enhance throttle response, horse power 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 Mustangs, a notorious issue for the 2013-2014 Shelby GT500's.

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 to 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 zero to maximum or anywhere in between 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 such as: SCT, Diablosport, Hypertech, Superchips, Bully Dog, and Edge as well as JMS' own BoostMAX Performance Booster.

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 Enhancer 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 2011-2017 Mustangs including the V6, EcoBoost, GT, BOSS, Shelby GT500 and GT350 models.

Would this compliment or even be necessary if you have the Ford Performance Power Pack 2 since ECU tune is included with the power pack?

Jeff49

  • The JMS PedalMAX Drive By Wire Throttle Enhancement Device can be used with the Ford Performance tune, allowing further adjustability of the throttle. Wile this would be a benefit, this will see greater benefits on an untuned car, since most tunes will adjust the throttle over stock.

Can I install this if I have a Bama X4 Tuner?

SixTimeChamps

  • Generally if you are using a handheld tuner on your Mustang then you already have an adjustment made for throttle enhancement. However, you can turn off the throttle enhancement from the tune and use this JMS PedalMax then you may experience better results. You will not find benefit out of this throttle enhancer if you already have a throttle adjustment made on the tunes your vehicle is running.

Will this product void my warranty?

SixTimeChamps

  • According to the Magnuson-Moss Warranty Act, a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause of or contributed to the failure of the vehicle (15 U.S.C. 2302 (C)). This means that a vehicle's warranty cannot be "voided;" the dealer can only deny a claim if the stock part failed due to damage or unreasonable use.

    Noticeable but not entirely necessary!

    Just installed the JMS PedalMax with the remote adjustment nob. Right off the bat you can feel and hear a difference! Less weight is required on the accelerator, it definitely feels like it picks up a little quicker now. In terms of the sound, it makes my Borla ATAK sounds louder than normal which is very loud. Love the product so far, bought the adjustment nob so I can turn it off when others drive my car, but not entirely necessary. I recommend to anyone that hates pedal lag and is looking to give there S550 a little more giddyup in traffic or wants a little more roar out of there exhaust.

    Great addition while keeping the factory warranty

    Having purchased a slightly used 2016 Shelby GT350 recently, there is not much that is offered in the way of performance upgrades and keeping the factory warranty. I happened upon a couple of reviews on the JMS product and decided to try it since it is not a tune and keeps me within warranty boundaries. Install was easy and the power although it does not add power, it makes it feels more immediate and linear throughout the RPM range. I give it a thumbs up!!!

    Great Product.

    A must add for Auto GT guys with after-market mufflers. After installing the after-market muffler, I have noticed having to push down on the gas pedal a bit further to increase RPM due to lost of back pressure. The acceleration is more responsive and the low RPM muffler drone is also eliminated.

    It won't cure turbo lag, but it does what it says!

    PedalMax does what it says, it cures the delay between pedal and throttle body opening. It also seems to get that throttle body open faster. On a 2015 Ecoboost I can confirm that turbo lag is still the issue for the first full second of takeoff, do not buy PedalMax thinking it will improve 0-60 times etc. What it will improve is responsiveness, and being already tuned I find it to further enhance my experience.

    Pony Enhancement

    Received my JMS Pedal Max yesterday, and 30 minutes later after reading the directions and turning the key, I was all smiles. Ya gotta be a bit of a contortionist installing but it's most certainly worth the price. I have 2015 Eco Stang with the Performance Package. To date I've added KandN Air Box, Bamma Tune, Ford Racing Borla Mufflers and X Pipe. these upgrades from AM made a HUGE difference in the stock Ecoboost performance. Wasnt' sure the JMS device could help but I was mistaken. I have the Automatic and love the paddle shifters. I can say that the car in Drive performs as well as it did in Sport before the addition. In both D and S selections the device got rid of pedal lag, seems to rev and shift much better with no delay and crisp.. I was truly impressed and for the price...a great bang for the buck. It does feel quicker....time will tell!

    A Must-have mod

    I spent a few weeks making up my mind between installing a tune and installing the PedalMax device, but I didn't want to void the factory warranty. I'm glad I chose the JMS PedalMax. Easy to install (5 minutes). The car feels wayyyy more responsive, it is really fun to drive now. In my opinion, it is a great investment. I've never been so happy with a mod than now.

    A Must Have Mod!!!

    I wasn't sure I wanted to spend that much on this device but I'm sure glad I did!! I have the Level 2 Roush Power Pac on my ecoboost and as great as the Tune is as compared to stock, the car still felt as it was still lacking! This device literally woke up my car, it feels much more linear now , you just touch the throttle now and the response is instant! I find it's a lot smoother off the line now , the turbo seems to spool up quicker, and shifting is a lot smoother now as well! Installation was relatively easy, simple plug and play, hardest part for me because I'm a bigger guy was contorting myself to reach up under the dash! I'm not sure if there is any actual HP gain but it should the heck feels like it!! If you're looking for that true sports car feel I highly recommend this!!! Saving up for the BoostMax now!

    Worth every penny

    Wow, this completely finished off and rounded out every mod I've done to this car. I've had the car for two years and in lower gears especially putzing around town in 25-30mph zones, the car felt like it would "gear down" or -- not quite stall -- but definitely the power arc would go down. To get the car to remain at RPM, if I gave a little tap to the pedal, the car would "come back." But for such a great little machine in every other respect, this was a blot and a disappointment. Why didn't it just remain at RPM?! I thought it was the tune and switched from a Bama tune to a MPT tune -- huge difference and seemed to even out he car (plus give even more power), before long, it went right back to dropping power in lower gears and at slower speeds. When I saw this part and learned about the drive by wire system (c'mon, Ford, really?!?!?), I knew this part was the answer. Worth every penny. And I'm not so excited about the instant response -- great, love it! But now the car just runs completely smooth even at lower speeds. Completely took the hesitation and uneven run out of this car. LOVE IT. Worth double to me for this reason alone much less the throttle response from start or at higher RPMs. Wouldn't even hesitate to recommend.
