Mobile Computer CAR interface

Hello my name is Jason, i'm new to the forum. i check the other forums this seems to be the best for my question.

Is there any program or devices i can connect to a computer to monitor my cars speedometer, tach, oil pressure, electronics, airbags?

Dont be shy with your answer. if you know of something please let me know. thanks in advance.

If your vehicle is OBD II, you can get this slick little programhere (http://www.obd-2.com/) . It's pretty cheap, and from what I've heard, its excellent.
