ODBII live scanner data

Any one know of a resource I can go to to learn more about the live data on my ODB II scanner so that I better understand the information? I understand some of the data like fuel trims but some of the parameters are still a mystery.

Thanks,

George

You might try a local junior college or a community college, sometimes they offer night classes. Another possibility is contact the manufacturer of your scan tool. Some have CD's available that explain how to use it, and interpret the data. A scan tool is a fantastic tool, but like a book, it's worthless if you can't read it ;)
