ECRI Wireless Vehicle Calibration Device

Jeep Model
Vehicle Unlock

ECRI Allows you to calibrate 2007+ Jeep Wrangler and Gladiator.  Just plug the ECRI device in your OBD port (2018+ Jeeps require a security bypass be plugged in as well) and open the ECRI app to get started.  ECRI allows you to view and update calibrations like tire size, TPMS threshold, TPMS disable, axle gear ratio, transfer case gear ratio and more!

  • ECRI devices are reusable on multiple vehicles.
  • Each vehicle requires an unlock, which can be purchased now or later in the ECRI app.
  • Starting with app version 1.7.1, codes purchased online will automatically be applied to your account as long as the phone number on your order matches your phone number in the ECRI app.
  • ECRI is compatible with 392 and 4XE models.

Did exactly what I wanted it to do!

Absolutely worth it!

I recently upgraded my 2018 Jeep Wrangler JL Sahara from the OEM to 33-inch Mickey Thompson tires and new 17" Quadratec rims. Without the recalibration my Jeep was very sluggish and gas mileage way off. The ECRI device completely updated everything, returning the gear shifts to where they needed to be and making everything much smoother. Gas mileage back where it should be. Completely worth the initial cost, and you can share it with others, minus a one-time $50 fee. Great business model and USA product. Thanks!
