Most Popular Flashcal F5 for 2017 Jeep Wrangler

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.

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.
