Review on Enhance Performance with ECRI Calibration Module for 2007-17 Jeep Wrangler JK - Unlock Features via in-App Purchase PER Vehicle by Vera Gashi

I used this to recalibrate the tire size on my Jeep Gladiator. Connecting the safety bypass was easy enough. When connecting the app to the ECRI module for the first time, there was a communication error and the app restarted, after which it was able to communicate and provide me with a list of settings. I tried to use the GPS speedometer function but it didn't work at first. I tried to manually adjust the tire size and when I entered the burning program it gave me a different error. I restarted the app, reinstalled the Ecri module and tried the manual settings again and it was able to record this time and offered to buy a one time key for my car then successfully wrote the programming. Then I tried it again with the GPS speedometer. and now it worked so that still seems quirky. I've also noticed that although it connects to the module and displays the options available, after making changes and rewriting the programming, half the time it throws an error and you let the app reset itself and try again . I've had about 50/50 success. Fortunately, trying again doesn't take much time or effort. However, sometimes after resetting the app it only showed half of the available options you could change and I had to close and restart the app again to get all the options. In general, everything works, but there are nuances that need to be corrected.
