Superchips (Flashcal) Programmer | Wrangler JK

Larger tires, gear swaps and other aftermarket products require a tool for reprogramming some factory settings. For our own personal and R&D Jeeps, we rely on Superchips Flashcal Programmers to get the job done quickly and easily. Featuring a color screen and simple to use interface, Flashcal corrects to your Jeep’s speedometer calibration for use with up to 42” aftermarket tires, gear swaps up to 5.38:1, locking axle settings and a whole slew of ergonomic features that make sense for daily use, but can get in the way off-road. Flashcal also reads and can clear error codes.
