Jeep JKU with larger tires...a must have...
Instructions advise to measure your tires. My tires are listed as 35x12.50 but my speed was still off by 5! I finally measured and turns out they were 34". Problem solved. Shifting and gears feels so much better especially with reverse and it's very easy to use. Wish I had gotten it sooner.
The Mean Green Machine gets Calibrated
Super easy, best bang for your buck. Took a few minutes to download the software on the FlashCal then off to the races. I put a lift and a wheel and tire package on my 2015 JKU. It calibrated the speedo and adjusted shift points so it pretty much drives like its stock but better. A nice thing too, for $90 you can upload you FlashCal and turn it to a flashpaq and get some power and fuel mileage settings. I did see an increase in fuel mileage also, and it works great with my air intake.??
