I just purchased an android tablet, and I've discovered an app that will read my truck's PCM data stream via a bluetooth transmitter that plugs into the ALDL. The app I got is called Torque, and it works pretty well, but I'm wondering if anyone knows of any others that might read more like a diagnostic scanner than a racing readout. I've only got about $30 invested in the app and bluetooth adapter, which is pretty good, but I'd like to find something a bit more comparable to a Tech 2. What do you have? How does it work?
