Thanks Cholltero....I always fear that I'm being a bit long winded with some of these posts. I would be happy to do a write on up OBD stuff, but unfortunately I really don't know all that much....the post I did earlier is really my first experience with that stuff. There is a Tech Article here on 4x4Wire, already. The article is a bit dated (some new technologies have been introduced since that article was written), but it was an informative article....that's where I started 2 weeks ago.

I can tell you this (the basics)....you need 2 items to be able to read sensor data...(1) an OBDII link device, which will rectify the voltages and signals so that your computer can read them (without burning the computer up), and (2) a software package that can read the input and display the date. The most common package I found was a device called "OBDLink" made by a company called Scantools and the software was called "ScanXL" by a software company named Palmer. I bought the whole package (link device and software) on Amazon.com for about $180 with shipping. Both companies have pretty informative websites and customer service contacts that are pretty helpful....and as best I can tell, the stuff does exactly what they say it does. There were other similar link devices out there...and other software packages but the setup I got seemed to be the most popular. And both companies offer multiple versions of their stuff (I went with the 'standard" package.

Anyway....all the info is available on the web....just do a search for "OBDII Link"....you'll get a ton of stuff.
