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.

2023 Jeep 392

This programmer is phenomenal. It is the only programmer on the market that would allow me to adjust the speedometer on my 392 Jeep. It was simple, fast and extremely accurate. I’d recommend this to anybody. I have used other programmers in the past, but this one beats them all, hands-down. The GPS option was amazing. Simple, and accurate.
Thank you!!
