I just bought a Scion tC (2008) and want to get the most I can out of the mileage.
I've heard there's OBD2 readers which can output to phones. I have an android phone that I would ideally like to use for that. I see so many options, some of which I am not sure actually even do what I think they do (show detailed readings of all sorts of stuff on a phone app).
I've also seen Mr. Money Mustache's article about the car computer that he bought.
Can someone who knows more about this than I do help me out?
