Review on Enhance Performance with ECRI Calibration Module for 2007-17 Jeep Wrangler JK - Unlock Features via in-App Purchase PER Vehicle by Bryan Fields

Impressed with ECRI. Provides reliable and stable calibration in minutes. The hardest part? For JL Wrangler 2018+: Locate and remove security packages (located in the dashboard above the OBD port). Totally doable, difficult to get to and reinstall the cables once complete. The ECRI app (iOS) is feature-rich, fast and easy to use. Today I used a tachometer calibrator for large 35 inch tires. ECRI did all this while I rode 3-4 miles. Noticeable switching points have also (significantly) improved. Impressive device, worthwhile (for me) highly recommend. Five stars.
