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.

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!

No, you cannot use the same Superchips Flashcal F5 Calibrator for Jeep Wrangler # SU3571 on both your 2018 Jeep Wrangler Rubicon and your wife's Wrangler. The Flashcal can only be used with a single vehicle at a time because the original tune is stored in the unit's memory.

Can SuperChips Programmer Tune a Second Vehicle If First Vehicle Wasn't Put back to Stock
No there is not. You might be able to contact SuperChips to see if they'll sell you a way to unlock it, but unless you can track down the original vehicle and return it back to stock their programmers cannot then tune a second vehicle. The programmers are designed like this so that you someone couldn't tune unlimited vehicles after purchasing just the one programmer.

Will The Superchips Flashpaq from Jeep Work On a 2021 Ford F-150?
Your 2021 Ford F-150 is going to require the Superchips Flashpaq F5 Pro Custom Performance Tuner # SU1545 as long as you do not have a diesel engine. Your Jeep JK used a different Tuner # SU3571 and cannot be reprogrammed for your F-150.

Why Would Jeep Wrangler Not Shift Properly After Gear and Tire Size Swap
Did you use the Calibrator # SU3571 to adjust for the gear swap and the tire size increase? Shift points are based on MPH, throttle position, and RPM so if the gear value isn't adjusted the vehicle won't know how to shift properly. If you did this already you might double check to make sure everything is set properly.

2016 Jeep Rubicon Unlimited Calibrator for Adjusting Speedometer
Yes, the Superchips Flashcal F5 Calibrator # SU3571 that you referenced has been confirmed to fit your 2016 Jeep Rubicon Wrangler and would help you change the speedometer for different tire sizes, but it will not give you additional horsepower.

Recommended Performance Tuner for a 2017 GMC Sierra 6.2L After ECM Replacement
Since you had your ECM replaced your current tuner thinks you have a new vehicle. You can try to contact Superchips and maybe they can reprogram it.

You would have to set the first Jeep back to the factory settings before adjusting the tire size on another Jeep with the Superchips Flashcal F5 Calibrator # SU3571.
