The JK Blaster is an essential tool for all Wrangler JK owners that run bigger tires, changed their gear ratio, or that want more functionality than what came from the factory. Plug-and-play installation, simply plug into the OBD2 port and then open the smartphone app to pair and program functions and calibrations to the Jeep. The JK Blaster has two types of features - changes made to the Jeep like tire size, gear ratio, and others to accommodate new modifications (these changes will continue to operate after the JK Blaster is unplugged) and the Tazer exclusive "live" features that only activate while the JK Blaster is plugged in. All features and calibrations are accessed using the downloadable JKBlaster smartphone app.
