Like $20 so for around $30 you would be able to read and clear ECM/TCM codes. Plus watch live data on customizable screens with your choice of line graph, bar graph, live number, half dial, half dial with live numbers,
So you could easily watch fuel trims from your phone while driving. Or check your speedometer accuracy vs gps speed.
If you correctly fill in the info about your vehicle then it has widgets to tell you estimated HP, quarter mile, eighth mile, 0-60, 0-100. A lot of things your car already does just an ability to back check them against each other.

Thanks so much for the info and guidance!
