Calibrate your Jeep to fit with your off-road ambitions. The Flashcal offers various Jeep-specific features, like real-time idle up, speedometer correction, and transfer case gear calibration.
Features:
Note: Not all features or monitored parameters are available for all applications. Available features and parameters will pop up automatically on the display once the Flashcal is plugged into your vehicle.
The Flashcal's off-road features include the ability to recalibrate your Jeep's axle gear ratio to improve 2WD shift points. Modify the transfer case gear ratio to improve your 4 HI shift points or your 4 LO shift points. Adjust the psi threshold on your tire pressure monitoring system so that you can deflate your tires for off-roading without sparking any annoying warnings. The real-time idle-up feature lets you set your Jeep to maintain power to auxiliary electronics at any preset rpm (up to 1,600). So you can power a winch or off-road lights while parked or idling.
With the Flashcal, you can raise the stock speed limit setting on your vehicle, and you can recalibrate your factory speedometer to correct for various tire sizes.

Calibrate your Jeep to fit with your off-road ambitions. The Flashcal offers various Jeep-specific features, like real-time idle up, speedometer correction, and transfer case gear calibration.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.
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.
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...
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!
Easiest thing I have done. Plug the device in and it will walk you through your steps. Worked great.
Product was on back order and took couple more days to arrive but great customer service from George and Brittany.
