Some of the features include customizable dashboards, real-time graphing of vehicle sensors, emission readiness status, data logging and exporting, oxygen sensor tests, Boost readout, and a full diagnostic report. Is your check engine light on? Do you want to monitor fuel economy and usage in your vehicle? Do you want cool looking gauges on your Android phone or tablet? If so, then OBD Fusion is the app for you! OBD Fusion is a vehicle diagnostics tool that connects to OBD-II and EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant?

The most extensive ODB2 app on Google Play. I found no other app that can get all the advanced codes like ABS, AWD, and even the Bose amp faults like this one can with the Nissan addon. It was well worth the $15 for the app and addon, as a comparable handheld scanner costs many times this. I can even track the reading of my wheel speed sensors (one of which caused my ABS light to stay on) in real time. And one small issue I had was QUICKLY addressed by support. This is the OBD2 app you need!

The application does not detect DTCs ... I have to start 3-4 times the applications for it to detect. I would like to be reimbursed ..
