When entering data on my 2007 Yukon Denali how do I get PIDS that relate to my engine

When I enter the serial number, gross weight, engine, there is no selection for the 6.2l engine. Only 6.0l and 8.1l. How can I get this changed for correct engine displacement and PIDS for logging. I'm ready for some data logging. Also I am wondering do i need to purchase and hook up a eternal o2 sensor to do my vve or is there a method where I can utilize the trucks o2 sensors.

2007 6.2l 376ci, Ported heads, comp cam 156-403-13, Air raid cold air intake, Jet mass air( not in use because still set up in SD mode), more up-grades to come.
Have the truck running and idling good and am ready to do vve, ect.

PS. Using EFI Live V2 here. Not sure how to paste tune and logs.

Scan tool: Edit->Validate PIDs will give you the supported PIDs for your vehicle.

Thanks that worked.
