For JL owners who want to run larger tires, adjust PSI or turn off TPMS for airing down, or change axle gear ratios, Z Automotive’s Tazer JL Lite Programmer offers and plug and play ease with intuitive user control with a clever array of live features you can adjust with your factory steering wheel controls and navigate menus right on your Wrangler's dash display (EVIC).

Programming takes only moments and free firmware is always available by connecting the module with an included mini USB cable.
