I've been doing some research in the mean time and found that there are fairly inexpensive cables and bluetooth dongles that you can buy to connect to PC, iPhone, and Android phones. There's software you can use to then monitor realtime performance (RPM, MPH, MPG, etc.) or pull error codes and such.
May be useful when the check engine light is on and you want to know what's wrong before paying the dealer for the diagnosis. I'm not interested in actually changing anything in the ECU, just pulling data from it.
