If you are looking for a way to monitor your car, then you should look into the Car Chip Pro Engine Performance Monitor.

The Car Chip Pro plugs into the OBDII port, which is found on the dashboard or steering wheel. When it plugs in, a tiny beep happens. Every time you start the car, you hear that tiny beep which shows that it is recording some seriously good information about your automobile.

When you pull up to the driveway, you can yank out the Car Chip Pro and connect it to your computer with the included USB cable. You can check out the On-board Diagnostics (OBD) like driving and engine performance.

You should be able to get the Car Chip Pro Engine Performance Monitor for about $99 on the CarChip site.
