SUPERCHIPS FLASHCAL F5 IN-CAB TUNER,GASOLINE,COMPATIBLE WITH 2007-2018 JEEP JK WRANGLER

Works great able to set gear ratio tire size scan for check engine light tire tpms lights off if your airing down for the trail and many other features easy to us and works fast ..

I have larger tire on my Jeep and my speedo was off about 10 mph. This thing was so easy to use. It was worth every penny. It also showed up at the house two days after buying it.

i got a new set of 37’s to replace the old. gas mileage went down and shifting felt very late. (assuming new tires are much heavier than old) Took a shot on the super chips flashcal. Updated tire size with this unit. avg gas mileage increased from 12.2 mpg to 16.2mpg on my first commute to work after updating. Shifting now feels very smooth and on time. id say this device pays for its self in gas savings alone. Not to mention turning off that pesky TPMS light! well worth the 200$ price tag. Just dont confuse the flashcal with flashpaq as the flashcal can’t tune, it can only calibrate a few options.

Just wish it had more tuning ability.

This allowed me to change my tires size to 35s and now I get 20mpg I love it

I purchased this after upgrading to 35” tires on my 2016 JKU. I noticed a HUGE difference in my drivetrain after rolling off out of the shop with 35” tires. It was slow to respond, felt a loss of power and I could tell that it wasn’t shifting where it was suppose to. I plugged this in, and literally in minutes had my new settings loaded and ready to go. Now, I purchased this solely for changing my tire size so I haven’t used any of the other options. (Gear ratios are the next mod which this will also take care of). I have gotten much of my lost power back, the gearbox shifts closer to the correct points, and my speedometer is worlds closer to accurate speed! Feel a lot more like factory! I’ve never interfaced with my vehicle like this but it was super easy to use. I read the manual and watched a vid on YouTube. There’s a load of other options that I haven’t had time to look at yet but it’s also a great feeling to know I can read and then clear any codes my Jeep throws at me and possibly fix myself. Very highly recommend!

I bought this to adjust the speedometer on my 2008 Jeep Wrangler that I put 5:13 gears and 35" tires on. Programmed in the parameters and the took the Jeep out for a test drive, way off. Adjusted tire size up and down and couldn't get the programmer to make the speedometer read within 10mph of actual speed. Called tech support and was greatest by Niel or as I now call him No help Niel. Described my situation and asked for some suggestions on how to proceed, Niel told me I needed the tunner and a computer so he could log into the device. I told him I don't have a computer to log into with and asked if there was anything we could try without a PC. No. That's the only answer he could give. I explained I go to work before the call center opens and am working well after they close and wanted just some pointers for when I get off. No. The guy had zero desire to help. I asked what it is I could do when I get home, plug into a computer and try... No. So you either have to schedule your day to be at a computer and wait on hold for tech support or get NO help. Thanks No help Niel. I was going to upgrade this unit but now I'ma box it up and get a tuner from another company that works through my cell phone.

The first unit I received had errors. Returned it to Amazon. Replacement arrived within a couple of day of starting the process. Replacement works as advertised. Set tire size. Set TPMS to 25. Not sure what the lowest or highest settings are, but it'll go at least as low as 20, and TPMS can be turned off completely. I haven't experimented with data logging (which it does while driving). It's somewhat expensive for what it does, but getting a dealer to change the settings isn't cheap either, if they'll do it, and this can be used as often as desired for the original cost. It can also be updated and upgraded online. Diagnosing and replacing missing files on a faulty unit could be done online, and the update app should be capable of doing that without requiring that a technician from Superchips have online access through a person's PC. I didn't take off a star for that, but Superchips really needs to up their game. Since I wasn't able to have myself, the tuner, and a PC all in the same place and make a phone call during their business hours, I just returned the unit.
