Limited Availability

Due to increased demand (thank you!) and supply chain delays, availability of ECRI modules is limited. We're assembling ECRI devices and making them available on this page as inventory trickles in. We've also been working the past few months to make our supply chain more streamlined to avoid future inventory outages. We do not offer backorders, instead inventory will be added to this page as it becomes available.

Thank you for your support!

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.

Quick, Easy, Affordable and Accurate

Not much to elaborate on from the review title. The calibration device does what it says perfectly and cannot be beaten regarding price comparison to similar devices from other companies. Glad to have it and would recommend buying it if you need to recalibrate anything on YOUR rig. The only reason it gets four stars is that although I have not yet tried, the setup seems to be that you have to buy an unlock code for each vehicle you want to use the device on; I wish it were universal.

2020 Gladiator

ECRI for my 2020 Jeep Gladiator worked great, I wanted to reset my speedometer and then also found some other settings I could change that I thought I was stuck taking it to the dealership to get changed. Great device and at a great price !

Calibrate Your Speedo

What a great way to calibrate your speedometer for your new, larger tires. Very reasonable alternative to the dealer. Turning on the fog lights with the high beams was an added bonus.
