ECRI Wireless Vehicle Calibration Device

Jeep Model
Vehicle Unlock

ECRI Allows you to update calibrations on 2007+ Jeep Wrangler and Gladiator.  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.

Works good used it to correct speed odometer. Used the gps function speed odometer is dead one. It’s super easy to use I do wish it would have the ability to turn off the auto start and stop. I would rate it 5 stars if it had that function

Great purchase!

Purchased the ECRI device for my 2014 jk after swapping tires to 35’s. It was easy to use and immediately made improvements in my shift points, the lag I was experiencing is gone. Annoying TPS is not staring me in the face either.


Veey easy to use and great product

Very easy to use

Have always been hesitant to use something like this thinking I would mess up my vehicle not knowing what I was doing, but after seeing a friend use his I knew it was as simple as it sounds. I had my wife’s jeep calibrated to her larger tires in less than 5 min. Lots of extra features too. Awesome product.

Great Tool!

I changed the tires on my 2017 Wrangler and I saw the was consuming more gasoline and a little bit slower on the response when I step the gas pedal, but since I got my ECRI it’s being a lot better on gas used and also the acceleration is better, so definitely it worth what I paid for it!
