Used once! Works great, just sold my JK so no longer needed. Please add ~$10 for shipping within US.

The Superchips Flashcal F5 Programmer for the Wrangler JK is expertly engineered to accurately correct your Jeeps speedometer following tire upgrades between 26” - 42”, as well as for gear/axle swaps up to 5.38 ratios. In addition, the Flashcal can adjust your engine idle for easier winching, sound the horn and flash exterior lighting on Keyless Locking, provide a daytime running light option and one touch lane change, read and clear diagnostic trouble codes, and can adjust your Jeeps TPMS - all from an easy to read high-definition 2.8" color screen.

The Flashcal F5 software is easily upgradable to the latest version with online access and includes a USB cable to connect to any Windows-based computer.

This application is designed to work on any JK Wrangler, however some features may only work on 2011-18 versions.
