ECRI Wireless Vehicle Calibration Device

Defective item receive

Was excited when I got it. Purchased the app as requested. It never asked me for a phone number during payment. But is supposed to send unlock instructions to that phone number. Had to wait for customer service to get back with me. Just follow the instructions and make sure Apple Pay has your phone number. Once logged in the app is very easy to use.

Bought this to recalibrate the speedometer on my jk for upsized tires and to turn off the tpms. It only took about 15 seconds to connect, another 15 to edit values in the app and another 15 to write the programming. The only issue I had was when you change the tire size, make sure you put a number in the second box after the decimal. For instance, if the tire size is 32.1, make sure you put 32.10 or the change won’t work when it programs.

Was apprehensive after reading some reviews. But reading and expecting in app perchase to commit changes, made this a breeze. Connected to my 2015 JKU, on screen app instructions were easy and I made multiple changees (Tire Size, DRL, Fog Lights w/ High Beams) in a few minutes with no issues. Great product, totally worth the investment.

So happy I found the controller. Simple to use and did what I needed and more. If you a Jeep owner do it! You can thank me later.... LoL
