ECRI Wireless Vehicle Calibration Device

Vehicle Model
Vehicle Unlock

ECRI Allows you to calibrate 2007+ Jeep Wrangler and Gladiator and 2009-12 Dodge Ram Trucks.  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.
  • 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.

Simplistic and effective tool to adjust settings on my JL Wrangler!

I have a diesel and where all others failed ECRI succeeded! Easy to download on my phone and with simple few steps it was up and running... Thanks so much ERCI for helping me and my Jeep out!

Great budget buy

This is an awesome calibrator at an affordable price!! Easy to use and the one extra bonus aside from the tire calibration is being able to keep the fog lights on while using the high beams.

ECRI - 2022 Gladiator

So far so good, was able to correct speed for tires and make the LED adjustments. Worth the purchase for sure!
