Most user friendly programmer - a little buggy I would easily give this app 5 stars if it weren't so buggy. Had problems communicating with ECM using recommended iCar module. Communication tests fail. I have to delete app and reinstall after each use, then re-pair module. A little frustrating, but when working this app is absolutely amazing!! Adding presets such as economy, power, etc. would put the icing on the cake. Thank you to the developer for their work on this!

What a difference an app makes! I drive a 2011 JKU with 35 inch tires and a 3.5" dealer installed lift. Always wondered if the computer onboard the Jeep was updated after the lift, which I found out is was not via this app. Using a GPS to determine the actual speed, I found it was 4MPH too fast. I then adjusted the actual speed to be correct using the app. It is AMAZING what the change did by simply correcting for the 4MPH caused by the tire size. It is abundantly obvious that the (auto) transmission shifts when it should now as compared to not shifting as it should before. The Jeep runs so much smoother and fuel economy has improved. All the other app features are great, but I am so thrilled for this easy and quick adjustment.

I don't usually post review but this app deserves one. It allows you to change tire air pressure sensor and tire size/drive ratio settings to accommodate changes you've made to your vehicle. It also has tons of other options and modules that can be activated and deactivated through the app. If your not sure it will do what you need d/l it and browse the demo. It does require a OBD2 adapter, but they're inexpensive. 100% worth the price. A big thanks to the developers.
