This is a must have for DIY Jeep mechanics. I diagnosed a bad O2 sensor (that was new) using the live stream PID data, saving me from buying new catalytic converters. I was able to calibrate a new throttle body intake. I also disabled the sway bar to shut off the light after installing a manual disconnect. Not to mention using the Trail view screen while 4x4ing to control the radiator fan and high idle features when winching...love it!!!!

Excellent app. Worth the money for in app purchase, though you can still see a lot of information in free version. Do yourself a favor and buy one of the listed compatible dongles. I had two very cheapies and neither would allow full functionality (but did allow to connect and read codes). Impressive amount of modification options. Just a really great app if u are modding a Chrysler/Jeep/Dodge. There is a free demo mode that requires no dongle but let's you see what is available for your model.

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!
