Jeep Wrangler and Gladiator owners are known for installing aggressive lift kits, massive off-road tires, and low gear ratios to conquer extreme terrain. However, leaving the factory computer uncalibrated after these upgrades ruins transmission shift quality, throws off mileage tracking, and triggers persistent warning lights. The Superchips Flashcal for Jeep (F5) is the most popular, trail-tested speedometer calibrator on the market built specifically to handle these challenges across multiple Jeep generations, including TJ, JK, JL Wrangler, and JT Gladiator platforms.

With the Flashcal for Jeep, correcting your speedometer for oversized tires (up to 42 inches depending on model year) and axle gear swaps up to 5.38:1 takes only a few button presses. Beyond essential driveability corrections, the device is packed with trail-focused features: you can adjust or completely disable TPMS alert thresholds for lower PSI when airing down on the trails, manually set engine idle-up speeds (ranging from 700 to 2000 RPM) to power winches or onboard air compressors, and control daytime running light (DRL) configurations. It also allows you to scan and clear diagnostic trouble codes on the spot. For owners who eventually want added horsepower, the F5 Flashcal platform is fully upgradeable to full Flashpaq performance tuning via a quick internet download, making it a versatile foundation for any Jeep build.
