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.

Must have to work on or customize your vehicle

Calibrated my Jeep tires to my speedometer spot on accurate, turned back on my daytime running lights, and configured my tire pressure monitoring in a few easy clicks. Didn’t even take me five minutes from when it arrived.

GPS based tire calibration is awesome.

Love this thing

Plenty of adjustment options for my jeep and works well. Also shows way more info on code scanner than your typical basic cheap parts store scanner.

Love it!

I like the fact that it actually does all the things my expensive bidirectional scan tool said that it did. Also the UI is easy to use and clean. Only reason for the 4 star is I almost got stuck. That was not ECRI's fault it was somthing Jeep did, but I did almost brick my Jeep. I would like to see the "learn new top gear" process for manual transmissions be done digitally. That is what the technician at Jeep said they do it and it would not require a road trip to finish programming your rig. Other than that it is worth the price it is priced at. Great little tool and the bridge can just stay plugged in so thats a bonus.

Works Great

I wanted a quick plug and play way of calibrating my Speedo for larger tires. I also used it to lower my TPMS threshold. The interface for iPhone is easy and not clunky like the interface of some of the competitors. Plug it in, open the app, make your changes and remove the ECRI for future adjustments. I highly recommend if you’re just wanting to make some basic changes and enable some of the features available on your Jeep.
