(1)Hey guys, Adam here with americantrucks.com. And today, we're taking a closer look at it and quickly installing the JMS PedalMAX Terrain Drive by Wire Throttle Enhancement Device for the '19 and newer RAM 1500, excluding the EcoDiesel. You should be checking this out if you're looking for a quick way to increase your throttle response and acceleration with the device that gives you the option to alter how responsive it actually is. Now, this device and other devices like it, throttle enhancement devices, in no way alter horsepower and torque. It's simply gonna either reduce or completely eliminate the drive-by-wire delay. Now the drive-by-wire delay is essentially the delay in time between hitting the gas pedal and your throttle body opening up and your truck getting going off the line. As you know, it gets a little bit sluggish, especially from the factory, and especially after adding larger wheels and tires like we have here on our '19 RAM. That can really slow down the way that this thing accelerates.This is gonna reduce and again, even eliminate depending on the setting you have it making it a lot more peppy. Now if you're looking to get off the line a lot quicker without having to spend big bucks on a custom tune, that gets a little bit messy, this can be a lot easier. All this does is it plugs right into your pedal harness, replaces it with this device here. And it comes with this convenient remote that you have access to within arm's reach of the driver seat. You can actively alter that drive-by-wire delay, but just quickly turning this knob. Now, the nice thing about this knob is it's got a lot of different settings and you can adjust it all in between those settings. It goes up to 50 up to 100, so you can completely remove that delay for full-out throttle response and acceleration.You could even go the opposite way and go down to negative 50. Now negative 50 is actually gonna add it to the delay, making your vehicle a little bit less responsive. That might be helpful with long road trips if you're looking to keep fuel economy in mind, it's not gonna be injecting as much fuel, it can dial back the acceleration and throttle response. It's also useful if you're handing your keys off to say valet, if you don't want them to have access to all of that throttle response and acceleration, you can dial that back so they're only limited there. It's good also if you're teaching kids how to drive, if you wanna dial that back and make sure that you're just getting the scope of how driving feels, they don't really wanna have all that acceleration at the pedal. Now this particular device here gives you the option to either screw it into a fixed position on the dash, or you can use the Velcro strips included in the kit, that way if you ever wanna remove it, tuck it away, you can do so just by pulling it straight off of that Velcro, but leaving a little Velcro strip there. Now the nice thing is we have that dark black interior, so the Velcro really does blend in with the dashboard, so it doesn't really stick out like a sore thumb. And then whenever you wanna put it back, you can just Velcro it back on. So that's really convenient there.It also has a device, the physical device that you'll tuck up under the dashboard and you can zip tie it back if you'd like. It also shows any data or warning lights there, if there were any alterations made with the device itself, you can read that right on the box. Now this guy here is gonna run you right around 350 bucks. Install is gonna get one out of three wrenches on our difficulty meter. Anybody can install this in five minutes or less in the driveway at home. Obviously, it can add a little bit more time if you want to fix it into the dashboard there using a couple of screws which are included in the kit, but it's either way, extremely, extremely simple. We chose to put it here on the left, sort of right next to our air vent just above our headlights, just because it's super easy to access and you can't really see it from other places in the vehicle so it's not sticking out like a sore thumb. You can put it a little bit lower on the other side, right above the PRND knob if you're looking to do that. You can put it really wherever you'd like. With that said, guys, I'm gonna show you the entire process. Let's get started.First step, climb onto your driver side dashboard, here you wanna take a look at your gas pedal. Follow the gas pedal all the way up till you see this black connector. On the front, there's a couple of ribs on each side that you're actually gonna pinch and pull out to unlock it and pop that connector straight off. Take your new JMS PedalMAX, plug that connector into the female side of the wiring harness on the back. That'll seat right in, it'll click. Close it down to lock it in place. Grab the other end and plug it into that factory spot. I know it's really tough to see here, but you're just gonna seat that back down to where the original one was, push it down and make sure it clicks. And then close the brown connector to lock it in place.Now we can plug our controller into these two wires coming off of that connector. This one here is just closed off, we don't need that guy when you disconnect it here. Grab the male end of the controller connector. Clip that guy in. Now if you want to you can grab the zip ties included in the kit and zip tie this stuff back. Next step here, we're gonna feed our controller up and mount it on our dashboard within arms reach of the driver seat. Now you can put this anywhere. I'm gonna put it right here. Now it does come with a Velcro 3M, so you can pop it up, stick it on, and then peel it off when you want to. If you wanna tuck it away or if you wanna remove it and make sure that the Velcro is still there so you can put it back if you'd like, or if you want a more permanent solution, there are two open holes and you can screw it into the dash for the guys who don't mind making permanent modifications like that. I'm gonna use the Velcro approach here. So what I'm gonna do first, is go under the steering wheel to this section here you can see a little cutout. This guy actually pops down really easily, just pinch and pop it down, just like that. That's gonna give us access to feed the controller up. So if you go underneath, you can feed that guy through, go in here and pull it through the rest of the way. Now, I'm gonna recommend pulling it up through this little opening, and then you're gonna basically feed it up through. At this point, you can just pull the excess wiring in so that can get tucked into this little cubby hole.Just make sure the wiring doesn't get pinched when you shut it. Just like that. All right. Pull a little bit more through just enough and I'm gonna mount mine here. At this point, I recommend peeling off the back of the 3M on the Velcro, stick it on the back of the unit. Put pressure on there so it makes a really good bond. Pick a clean spot on the dashboard and if you have to, you can use alcohol wipes or something as similar to clean it off. You don't wanna use detailer. Detailer will make sure that 3M does not stick the opposite of what you want, so make sure you're cleaning it off with something like alcohol or soap and water. At that point, peel off the backing on the other side, square it up to where you want, put pressure, and you're good to go. Make sure all excess wiring is tucked up and out of the way of the pedals you don't want anything getting caught on the pedals. And then at that point, guys, you're good to go. And, of course, if you set it on zero, that's your stock mode all the way up at 100, is full throttle response, back down to negative 50 is gonna reduce your throttle response. Great fit for like valet mode, if you're handing the keys off to the kids, something like that. But that's as easy as it is. And you can alternate this between the settings while you're driving actively and it will actively respond. But at that point, guys, you're good to go.That's gonna wrap up my review and install for the JMS PedalMAX Terrain Drive by Wire Throttle Response Controller, available for the '19 and newer RAM 1500, excluding the EcoDiesel.

Noticeable Difference with Acceleration
Installation is a breeze! After watching a YouTube tutorial, it only took ten minutes. To avoid excessive wire hanging, keep a few extra zip ties on hand. The throttle response was sluggish after installing aftermarket wheels and tires. I'm very pleased with the end result after installing JMS PedalMAX and fine-tuning it a little.

Amazing!!!!
I was skeptical of this thing at first but after reading the reviews I decided to give it a shot and man I'm happy I did! 0 is stock 50 is great pedal response and 100 is put you to the back of your seat amazing! From any speed you can feel the difference. I installed the Borla ATAK exhaust and the S&B cold air intake a month ago and this really made it all come together! The negative settings will be great for off road. It definitely gives you a smooth pedal with no extra torque. The only negative thing i would say about this is the adhesive strip they give you to mount the dial. It only held for about 5min before falling off. Small price to pay for such a amazing upgrade

JMS PedalMAX Makes You Smile
The only complaint I had on my 2020 Ram Laramie Sport 4X4 was throttle response. I was shopping for a tuner when I saw the PedalMAX add. One of the things I love about YouTube is no matter what you need a little info about someone has been there and done it on YouTube. The reviews for the JMS PedalMAX were all positive and the videos of the added throttle response were seemed to good to be true. The video of how the PedalMAX works and showing the changes it made to the operation of the throttle body was also very important for a car guy who understands what it was doing. I ordered mine and as soon as it arrived I got to work installing it. The instructions are precise yet so nicely done that a person with beginners mechanical skill can easily install the device. I had mine on and ready to test in less than 1/2 hour. The results are incredible. I don't know of anything in the market of bolt on upgrades that can match the amazing improvement to throttle response the PedalMAX makes for $300 bucks. I don't know of any investment on performance devices that makes driving your vehicle more fun for the money you pay for the PedalMAX. I've had mine on for about 6 months and I have ZERO complaints to report. I will install a JMS PedalMAX on any vehicle I purchase in the future if JMS has one for the vehicle. The JMS PedalMAX is one of those rare products that has to date all 5 star reviews based on the reviews I have been able to find on the web. All performance car enthusiasts that I have read reviews by and people I personally know who installed a PedalMAX agree that this amazingly simple to install device is the best money you can spend for an immediate and incredibly improvement to your vehicle. Simply an excellent product that makes you smile everytime you drive

As advertised
Easy install. Works as as advertised I really like the fact I can adjust in either +\- for acceleration. I tested it in reverse going uphill on gravel, in 0 factory set up I had wheel spin, made an adjustment to -25 and drove out without any wheel spin. Nice!
