Superchips Flashcal for Jeep

The new Flashcal for Jeep from Superchips is a must if you increased your Wrangler’s tire size or gear ratios. The tuner is able to correct your speedometer for tire upgrades between 26-in. and 42-in. and for gear/axle swaps up to 5.38. In addition, the Flashcal can also adjust your engine idle for winching, daytime running light options, and TPMS sensor adjustments among others.
