There are various other threads discussing OBD2 and PIDs and such. The Other threads have pointed to my personal csv file for downloading but I'm not positive I've incorporated everyone's feedback/comments. So I decided it would better to make this more public so I've moved all my Volt PIDs into a shared Google docs that everyone can read/edit.

If you have used these PID and "validated" or have better calibrations for any unknown fields please update the spreadsheet linked above.
Discussion about some calibration processess and data fitting can be found in this thread

Update:
How to get started using OBD2/Torque to get your own kWh meter.
Get an OBD2 Scanner with ELM327.. many choices on ebay . I've had best luck with VGATE branded ones (blue) with only 1 bad out of 6 bought. Cost is 15-30$ depending on what you get and how fast.
Get an android phone or tablets. Don't need the phoen to work so if on a budget an old phone (I've used G1s) or a phone with a bad EIN (so not really a phone any more) are good low cost options. A 7" or 10" tablet gives you more room for your screen.
Get Torque Pro from the Google Play store (You'll need the non-free $5 "pro" version to use custom PIDs which you'll need)
Plug the OBD2 connector under the left side of drivers dash. Enable bluetooth on the phone, start torque. Make sure it connects to device.
Follow the instructions on the "Notes" tab of the google doc to load the custom Volt PIDs. You might want to check back to get updates every now and then.
