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

Let me start with a positive note. I could change the tire size and that's why I bought ECRI. The downside is how long it took. First, 2 different iphones didn't connect. Switched to an Android tablet. Managed to download the Android app. However, I had to remove and insert ECRI multiple times, as well as start/stop Bluetooth on the tablet. Finally managed to connect and edit the tire size. Went to write and I was offered to buy. Bought the rights to the car but when she went to check the rights she just kept shooting. Application terminated and restarted. I went through the programming again and then said I need to buy again. I went to buy and it says I already have it. So the app closed, restarted and went through the programming again. Go through the programming sequence. Then I tried to read out the new settings. A "network" error has occurred. Went through the same Bluetooth kill sequence in Android. Remove and reinsert ECRI. Finally connected and read the new parameters. Consider the so-called history function. It doesn't display anything, so I'm not sure what it's about. Would have given it a higher rating since it did its job but the app is riddled with various bugs that are very annoying for the user.
