Figure 1. Tools of the Trade: a Nexus 7 Tablet and a Soliport Bluetooth OBD-II Scanner

Software-wise, my choice for this on Android is Torque, an excellent app that not only can collect all the OBD-II stats, but also graph and log them in myriad ways. (There’s also a free version, Torque Lite, that has a fair deal of the functionality of the full version.) Grab either one from the Google Play store.

Note that this solution is for read-only access to the OBD-II system in the car. You can’t modify the running parameters of the vehicle with this adapter, unfortunately (or fortunately, perhaps, as it’s very easy to make a mess of things). Flashing your car’s computer with a new fuel curve or ignition timing map is a nontrivial exercise that requires an adapter with different voltage levels and different software. So, don’t worry about breaking your car with this solution—you’re just “peeking under the hood”.
