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.
