After looking at many options for a way to change the speedometer of my 2015 JKU Rubicon to accommodate the larger tires that were on it, I finally settled on the Superchips Flashcal F5 3571. I watched for months, hoping to catch a deal on it since I wasn't very excited about spending my Jeep budget just to fix the speedometer. I finally found a deal that I could live with at etrailer.com. Their price was well below every other option.

I was informed via email that my order would ship in the next 7 days. I had already waited months, so not a big deal for the price. 3 days later Brittany called just to let me know that they hadn't received the item yet, so it hadn't shipped yet. I really appreciated the personal touch, even though I wasn't expecting the order to be shipped for another 4 days. The order arrived 10 days after ordering, well packaged and just as advertised.

I read the directions, connected it to my computer and installed the latest updates. I then connected it to my Jeep. Like the instructions said, I measured my tires (my 35s actually measured 33.5") and entered the information into the Flashcal. I also changed the DRL settings so that my headlights come on. My tires are aired down, so I was wanting to shut off the TPMS, but much to my surprise there was an option to change the TPMS level. I had read all kinds of reviews and watched videos, but that option never showed up. I was thrilled to say the least!

At this point, I grabbed the GPS and went for a test drive to check the speedometer. It is now spot on and a hidden benefit is that when I changed the tire size, it automatically changed the shift points. My Jeep drives so much better now! I really wish that I hadn't waited so long to make this purchase!! Full price would have been worth all of the benefits that it provided. 460081

First off, GREAT PRICE from etrailer. The product itself is a must have if you have larger than stock tires on your Jeep Wrangler. The programming is smooth and seamless. 5 star company, 5 star product. 585750

Worked perfectly for my needs. Installed larger tires on my JK, needed this to set my tire size to correct my speedometer. Worked flawlessly. Thanks! 587723

I love this thing, easy to install and use, went from 12mpg up to 22.
I also have a induction system and throttle body spacer, best money I've spent... 824106
