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.

Excellent Product Easy to use

I used this product to turn off my TPMS light. Download the app and follow the on-screen prompts. Everything else was super easy.

Don’t waste your money

It never worked right
TPMS never went off , also
It never said it was one time use only without additional $$$

Sorry you're having trouble with the TPMS settings. Please feel free to contact our support so we can help.

The unlock is for one vehicle, but doesn't limit the number of times you can program that vehicle.

It works as described. Extremely ease to use with the app. Very happy with everything it does. Highly recommend it to anyone that is looking

Jonathan G. (Texas, United States)
Works as advertised

Very simple and easy to use. I really love the GPS feature to figure out the correct factor for the tire size change.

Works well once all set up, couple more features would be nice.

Delivery took forever and I only chose standard priority mail. Every time I pay extra for faster delivery, UPS and Fedex just send me delay excuses and it just doesn't ship any faster.

The online requirement, location data and shutting down in 10 seconds caused me some issues. I had to allow a few changes on my phone I don't normally use to get this to work. Also had to stand outside the truck to pick up our wifi (could only get it to work with 5g wifi connection) for a strong enough signal, but every time the OBD connection would shut down. Input name/password again and unplug and plug the unit back in.

Just seemed to be a few unnecessary steps that caused a bit of frustration before it all finally allowed me to make changes. Initially made me feel like just sending it back.

I used it for tire size (measured tires, did not try GPS) and pressure, plus the hood alarm. Would be nice if it disabled start/stop and could activate locker in 2wd, but it's not a tazer, nor does it cost as much.

Pretty happy with the unit, once I was able to get it working.
