OBD GPS Logger does exactly what it says on the tin. OBD GPS Logger logs OBDII and GPS data on Mac OS X and Linux.

OBD GPS Logger can then take that logged data, and write useful output formats.

Your car has lots of interesting things it can tell you from its on-board computer while it's running. Things like how fast you're going, how fast the engine's going, the air flow into the engine, the throttle position... everything. If you want to know more, google obdII, and enjoy the rabbit hole.

As with so many open-source projects, this is scratching an itch: There's a severe lack of applications that run on Mac OS X or Linux that can log OBDII data.

The developer's idea was to be able to log this stuff as he was driving, along with GPS position, and later on plot an overlay on a map of where you drove, and how efficiently the car was running at each instant.
