JL Programmers

When you’re updating tires, changing gear ratios, or adding new electronic systems to your Jeep Wrangler JL, the factory ECU tune might hold your build back.

Whether you’re running bigger tires, regearing axles, or installing custom lighting and electronics, proper calibration avoids limp mode and maintains reliability. With TrailRecon, you get performance-tested tools from trusted brands that let your JL perform at its best, on and off the trail.
