      Video Review & Installation

      I'm Ryan from, and this is my review of the Superchips Flashcal F5, working with all 2007-2016 JKs. This is for those of you who have added larger tires onto your JK and are looking to make sure that your speedometer and odometer are accurate as well as adjusting your automatic transmission shift points for those new larger tires. If you've regeared your Jeep, this will allow you to make those adjustments as well in order to keep you from going into limp mode. And this also gives you a lot of other adjustability for everything from the TPMS system to your horn and headlight options, to your locker options if you have a Rubicon that has factory electric lockers. I really like this system because it has a screen on it which makes it really easy to use as opposed to some of the other calibrators out there on the market that just use dip switches. This is fairly priced, and you can always upgrade this if you decide that down the line, you're somebody who wants some additional tune options so that you can run a higher octane fuel and squeeze a little bit more power out of your JK. The F5 is Superchips new version of the Flashcal. The old version had a lot of the same functionality, but this one is much more sleek and modern looking. And it includes a two-and-a-half inch HD color screen which just makes using the programmer a little bit more pleasant. Now, this is the Flashcal and Superchips also has the Flashpack. The Flashpack comes preloaded with a couple of different tunes for higher octane fuel which again will allow you to get more power out of your JK. You can always update your Flashcal and turn it essentially into a Flashpack by adding those tunes at any point by going to the Superchips website, paying some additional money and downloading those tunes onto this device. These devices work by just plugging them into the OBD tube port on your JK and usually turning the key on and off, pressing the okay button a couple of times and giving you access to the main menu. From there, you'll be able to make all of the adjustments to all of the different settings that we've mentioned. So when you get this calibrator home and take it out of the box, the first thing I recommend is to plug it into your computer with the included USB cable, go to the Superchips website and download the program that allows you to update this system. From there, you'll also be able to download the free TPMS adjustment software so that you'll be able to turn this system on and off so if you're running a larger tire with lower tire pressure or you're offroading your air down. You don't have to worry about having the TPMS light on your dashboard and having that annoying dinging every time you start and turn off the Jeep. Now the main functions of this system that most of you guys are going to use is the setting for newer tires. You can adjust tire size for up to a 42-inch tire. And that's important again for a couple of different reasons. It will make sure that your speedometer and your odometer are accurate which will also affect the on-dash miles per gallon gauge. But if you're an automatic transmission guy, this will also adjust to those shift points to give you back that more stock feeling even with larger tires on the Jeep.Another setting that will get used a lot is the gear ratio setting. So if you've changed the axles on the Jeep or if you just regeared the factory axles, you'll be able to change the setting in the computer for up to a 538 gear. Which again, will make all of the adjustments for speedometer, odometer, shift points and get everything back to as much as a factory feel as you can without adding a tune or any power adders onto the Jeep. So the tire size, the gear ratio, and the TPMS system on and off are the systems that a lot of you guys are going to use the most. But that's certainly not all this can do. You have a lot of other options especially for the newer JKs as far as how long the interior and exterior lights stay on after you turn off the Jeep or when you unlock or lock it. You can also adjust whether the horn chirps when you lock and unlock the Jeep. You'll also have the opportunity if you have a Rubicon to customize the way that you can use those lockers all through the system. If you have a winch on the Jeep, you can bump up your idle with this unit to give you a little bit more amperage out of your alternator and keep the battery charged up during long hard pulls. All of these are very easy to change and to modify with this system, again, thanks to the color screen and the buttons as opposed to some of the other systems on the market that in my opinion aren't quite as easy to use. Aside from all of those calibration options that we talked about, this system will also read and clear check engine lights, which is a really nice feature to have. You don't have to run out to the parts store every time you have a check engine light to see what it is. You can read it, clear it if you want to, all from this unit which is a really, really nice feature to have. All in all, I would say that this system is really fairly priced. It gives you all of those calibration options right out of the box for under $200. The screen and the buttons make this really easy to use. It's really fast at updating the Jeep, and I have no issues with the user interface or with any of the options that it gives you. I also like the fact that this is upgradeable to essentially the Flashpack that you can pay a little bit of additional money and download those tunes for higher octane use onto your Jeep. So if you decide you want a little bit more power down the line, you can always upgrade this unit without needing to replace it. So if you've added larger tires on to your JK, regeared or you just want options to change a lot of the other conveniences and your TPMS system, this does all of that, and it does it for under $200 with a really easy to use interface.So that's my review of the Superchips Flashcal F5 working with all 2007-2016 JKs that you can find right here at
