Default Reading OBD-II Sensors

Alright so I picked up one of these $52.99 - ELM327 Bluetooth OBD-II Wireless Transceiver Dongle - OBD/OBD2 Car Diag. Tools it works awesome with my Torque app for android, my hangup right now is that I cannot see my bank1 sensor1 o2 sensor, which for the LNF is a wideband and thus a non-standard address. I think I found the info I need to plug in to make a custom PID access but I'm slightly confused. http://service.gm.com/gmspo/mode6/pd...0Injection.pdf

The information I think I need to plug in is as such:
PID(hex) 018305
Longname Wideband
Shortname AFR
Min 0
Max 1.999 (changed to 2 since it only takes whole integers)
Scale x1
unit type N/A
equation A*14.7 (for gasoline)

The equation is to get AFR from lambada since I believe that's what the sensor is putting out. Can anyone confirm the address for me?

Well that address doesn't put out the numbers I'm looking for, think that's actually a temperature address for something. Anybody have a better PID list?
