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.

Great product! Easy to use.

Great product! Easy to use. Was able to quickly program my new tire size and change my TPMS thresholds on my 2021 Gladiator. Would have given 5 stars but GPS function would not work on my vehicle. With that said I contacted support and they quickly reached out to me. And are addressing the problem .

Good Product

Bought this to reset the tire size on my wifes Wrangler, did its job. The additional function of reading Check Engine Lights is also nice since her Small Evap Leak code keeps triggering and the ability to change the Daytime Running Lights is nice. If you are modifying your ride this device helps out alot

For the price seems to fit what I needed. Took several attempts to get everything set up correctly. Still about 4 mph of from GPS Pegram.

Great device, some quirks.

The ECRI accomplished everything I needed it to. Tire size: check, TPMS change: Check! There were a couple of hitches though. GPS tire size calibration is buggy. Sometimes it works, sometimes not. They're not kidding when they suggest that a driver not be the person to manage the app while calibrating, but you also don't want just anyone doing it. While I didn't run into this, it seems like there needs to be an interlock to prevent pushing a program while the car is in gear. The engine will stop during a reprogram, so if your passenger hits the wrong button while you're driving you may be in trouble. Also, whenever I push a recalibration, I get a Service code and a check engine light that can't be manually cleared. You've got to wait for the Jeep to clear the code on its own. It's not clear whether the code is related to the bypass module, though I expect so. This is where documentation (not a forum or website) would be handy.
