The Jeep Wrangler is one of the most upgraded and accessorized vehicles on the planet.

If you’ve made aftermarket upgrades to your Wrangler, we’re guessing you’ll want to take full advantage of them. Things like larger tires, bigger gears, and lift kits, necessitate some adjustments to your Jeep’s factory computer settings, so Superchips developed the 3571 Flashcal F5 Tuner for 2007 and newer Jeep Wranglers. This Jeep-specific tuner lets you recalibrate your speedometer for bigger tires and gear ratios up to 5.38, ensuring you get accurate readings and optimal shift points.

The Flashcal F5 Tuner for Jeep has an impressive list of other functions as well. For example, you can manually lock your front and rear axles in 4-High mode, disable your TPMS sensors for off-roading, and raise your engine idle speed for when you need to use your winch. The Flashcal F5 also reads and clears trouble codes and allows you to adjust things like headlamp and radio turn-off delay after exiting the vehicle.

While the 3571 Flashcal doesn’t include performance tunes out of the box, you can add Superchips’ performance, towing, fuel mileage, and crawl programs online via Superchips’ downloadable software upgrades. So if you want to add more performance down the road, it’s quick and easy.

And speaking of quick and easy, the Superchips 3571 Flashcal F5 is simple to install and use. Check out this video for the visual proof.
