Imagine if you bought a new phone and weren't able to change the background, screen brightness, ringer volume, etc. Just like your phone, your vehicle has a lot of settings that can be changed. Until now, these vehicle settings have required expensive and/or difficult to use equipment to calibrate. ECRI lets you change those settings wirelessly and customize your vehicle just as easily as customizing your phone.
Download the app to your iOS or Android phone or tablet. Open the ECRI app and you will see it trying to connect. Plug the ECRI device in the OBD port. Your ECRI app will finish connecting, decode your vin, retrieve a list of available settings from our server and display those settings along with their current values in a list for you. Select the setting(s) you wish to change and type in a new value. Click the write programming button, then follow the on-screen prompts.
Within seconds your vehicle will be updated. After programming, unplug the ECRI device and keep it for next time, or share it with a friend.

Have one for the JL and it is awesome for the price. Does what I need it to. The Tire size calibration is dead on with GPS. Thanks a bunch.

Put dynatrac axles in a jeep and turned off the FCA and the factory lockers! Great product!

Purchased for my 2020 Gladiator after lift and changing tires to 35's. ECRI was easy to physically install, and even easier to program through the app. I am very pleased with this device.

Just did a test drive after changing my tire size. It’s a huge relief not having to guess my speed due to larger tires while paying a fraction of the fee a dealership would charge. Works great and easy to use.

Works great. I had a problem that was my fault, and got a reply from support in less than 10 minutes! Fast shipping, and great support. Works awesome did everything I needed it to do, especially for not having the price of some of the other ones I looked at. I would definitely recommend.

I loved the easy of use. I would recommend this to anyone. I was able to calibrate my Jeep JL Speedo in less than 5 min.
