      Video Review & Installation

      Hey, everybody, I'm Justin with, and this is my quick overview of the JMS single remote adjustment knob that does work in conjunction along with your JMS ThrottleMAX or FleetMAX, available for your 2005 and newer Mustang. This short vid is gonna cover the basic purpose of going with the JMS single remote adjustment knob here for your JMS ThrottleMAX or FleetMAX, along with the basic operation and installation. And right up front, you're gonna expect a very simple one out of three wrenches here because this thing is completely plug and play, with any of your JMS modules. And we will have a little bit more detail on that later on. Plain and simple here, gang, the JMS single remote adjustment knob is gonna be for the Mustang owners who have already purchased or plan on purchasing a ThrottleMAX or FleetMAX, both from JMS, and just simply want a little bit more adjustment when it comes to functionality. Along with being able to make these changes on the fly, this is not possible without this remote knob here from JMS. Now chances are, if you're watching this video, you're probably already aware of what the JMS ThrottleMAX is all about, but if not, here's what you can expect in a nutshell. The JMS ThrottleMAX is something that modifies the drive by wire signal in your 2005 and newer Mustang, increasing your drivability and your throttle response, while eliminating that annoying throttle lag.So why would you want to look into the single remote adjustment knob here from JMS? Well right of out of the box, guys, that JMS ThrottleMAX is gonna come with essentially two different settings. Unchanged out of the box, you're getting 100% maximum throttle response or maximum effectiveness. Now, JMS also throws in a red four-pin connector along with the package here, that's gonna essentially desensitize your throttle sensitivity by about 40%. But this is it, this is all the adjustment you have. And on top of all this, you have to crawl underneath the dash, mess with these plugs. Not exactly something you can do on the fly. And that's where the knob from JMS comes into play. This gives you far more levels of adjustment than you had before without the knob present and it gives you the ability to do all of these changes on the fly. Again, something you could not do without this knob from JMS. And this is great depending on your situation. Maybe you want to tone down the ThrottleMAX when you're stuck in heavy traffic or maybe you really want to crank this sucker up when you're ready to do some spirited driving. Whatever the case, the knob from JMS is a great way to help you out. And if for whatever reason you ever wish to turn off the ThrottleMAX completely while driving, that is something that is possible here with the knob. Simply turn it all the way to zero and effectively the ThrottleMAX is not on anymore. And again, this is something that you couldn't do without having the knob installed in your ride, without physically crawling underneath the dash and unplugging the ThrottleMAX or FleetMAX in your ride.So we established that without the knob in place, the ThrottleMAX is essentially only giving you those two settings: the 100% sensitivity or desensitized by 40%. What kind of adjustment are you looking at here with the knob? Well, JMS sets you up with 25% increments here with the knob, starting at zero, 25, 50, 75, and 100. But you're not stuck with these increments, you can go anywhere in between 25 and 50, 50 and 75, you get the point. Basically, you have endless levels of adjustment here with the knob, depending on your driving style. As far as price, I will say at around 50 bucks. It's really not that bad of an add-on on top of your JMS ThrottleMAX if you've already purchased one. Especially if you're the type of Mustang owner out there who always likes to play with stuff or tweak your settings, this would be an awesome choice for you. On the other hand, if you're the set it and forget it type, save your 50 bucks and just go with what JMS gives you right out of the box. I will say though, at 50 bucks, on top of your ThrottleMAX which is about 280, you're still looking at a relatively affordable mod compared to some of the more custom tuning options out there. So if you're not quite ready for a custom tune just yet or you have your own reasons why you don't want to go with a custom tune, the ThrottleMAX along with the throttle knob here is a nice way to get some of the benefits of a custom tune, like that improved drivability but without going all in on a full blown custom tune. As far as the installation, well like I mentioned earlier, one out of three wrenches on the difficulty meter. Plug and play install here, guys. We call it 30 minutes on the site from start to finish, but honestly, most of your time in that 30 minutes will probably be spent deciding on where you want to put the knob itself. I've personally seen a lot of guys put them underneath the steering wheel, on the dashboard. You can also throw it into the center console for maybe a stealthier approach. Whatever the case, JMS is giving you five feet of cord so you have some options to work with. They also give you these two little holes that are probably gonna be used for some screws. I don't know about you guys but I don't want to drill anything into my dashboard. So, clean the area really well first using some alcohol prep pads, throw some 3M automotive tape on the back of this thing, save you from having to drill into your ride. But again, you have some options and ultimately, look forward to a very simple install. Wrapping up the adjustment knob here from JMS, if you've already pulled the trigger or thinking about pulling the trigger on a ThrottleMAX, pick up the adjustment knob, and here's why. The amount of adjustability is worth the price of admission alone, but factor in the ability to make all these tweaks on the fly, and that's where this product is really gonna shine. So that's my review of the JMS single remote adjustment knob which you can find right here at
