Can anyone tell me how I can turn off the rear O2 sensor using HP tuners as well as the Purge valve. I am doing a swap into a 69 Chevelle and don't need the O2 or the Canister to work.

sure bro,
Open your tune, click on Engine diag tab ( just to the right of engine )
click on DTC ( all the way to the right)
Look for bank 2 in discriptions.
Uncheck the box and click the error mode to 3-report no errors. That's the easy way.
The best thing to do is open your scanner, look at the top left where it says window, right under that word is something that looks like a picture of an engine. Run your mouse over that and it will highlight DTC. Click on that. To the left of that screen there is a picture of a blue floppy disk. Right next to that if the scanner is running is a check mark and an X. Click on the X to clear your codes then click the check mark and go for a drive. The codes that come up pertaining to your engine are the ones you may want to turn off or check for a problem.
Enjoy

Ok.have all of that done.
if I am looking in the Engine Diagnostics window and have the General Tab open what exactly is the Post O2 test? shouold this be disabled as well or no?
Still need to know how to disable the purge valve.

Purge valve - don't plug it in. Disabled. Then as previous poster said check for codes. Which ever coded are logged for it then disable with 3-no report
There is not magical on/off for every sensor on car. They all rely on unplugging and setting codes correctly to disable them.
