    Video Review & Installation

    I'm Ryan from, and this is my review and installation of the Superchips TrailCal, fitting all 2015 and up JKs. Today we're gonna talk through the installation of the TrailCal, which isn't much of an install at all. This is a one outta three wrench install. You really just attach it onto the dashboard, plug it into the OBD-II port, but we'll talk more about that in just a second. We're also gonna talk through some of the features of the TrailCal.Anytime you upgrade to a larger set of tires or change the gear ratio on your Jeep, it's always a good idea to recalibrate the Jeep's ECU for those new parameters. That's going to ensure that if you have an automatic transmission, that your shift points are correct, and at the very least, ensure that your speedometer and odometer readings are accurate. Now you can make all of those changes with a Superchips FlashCal or with one of the other calibrators on the market. And those calibrators are really designed to plug into the Jeep, make some changes, update the ECU, and then unplug it. And you really throw that calibrator in your console or in your glove box, and you don't use it very often after that, unless of course you wanna make some other changes. And these calibrators don't just change for gear ratio and tire size, they'll also do things like convenience options, like how long your lights stay on, your radio delay, horn chirps, they'll adjust for idle for if you're winching and you want a little bit more alternator output, TPMS systems. They'll make a lot of other adjustments as well.Now, the benefit to something like this, which is the TrailCal, is it does all the things that the Superchips FlashCal is going to do. But instead of just updating things, unplugging it, and throwing it in the center console, this is something that's designed to be left on the dashboard, give you readings for all of your gauges, give you digital readouts. This will also allow you, with an additional module, to have virtual switches for lights or lockers. This is really going to give you a lot more control and a lot more information, all while having that little screen up on the dash all the time, a touchscreen, that you can go in, swipe through, and get a lot more information about your Jeep in real time. Now, the difference between this, the TrailCal, and the TrailPaq is going to be that this does everything that the calibrator does, that the FlashCal does, but the TrailPaq or the TrailDash, is going to be more akin to the FlashPaq, which is going to also have tunes. Now the tunes are going to adjust for timing, fuel, a few other engine parameters. You're going to wanna run a higher octane fuel, and you're going to get a little bit more power out of your Jeep. Now when we're talking about the 2015 and up JKs, which is what this does, you can't just hook a tuner up and have things work, you actually have to swap out the ECU. So if you are interested in getting tunes, if you want some additional power, you're going to wanna go with the TrailDash and you are going to have to swap out your ECU. If you're not interested in additional power, you just want a calibrator that is also going to give you a lot of other information about your Jeep, then this is going to be a really nice option.So as I said, this is going to give you a ton of information about your Jeep. You are going to have a five-inch color touchscreen, which is going to allow you to very easily access all of that information. It's going to read and clear "Check Engine" lights. You are going to be able to control factory options on your Rubicon Edition Wrangler. If you have factory lockers or sway bar disconnects, you can control that through here. This is also going to have an additional video input, so you can actually run your auxiliary reverse camera through this screen here. But as we mentioned before, the real meat and potatoes of this, the real main point of this, is to calibrate, so you're gonna be able to cal
