Practical Reflash Tuning Calibration

My GM ECM is very different in the Fuel fields, I'm having a bit of a tough time. When I click on the fuel tab, I have 8 fields ( General, Oxygen Sensors, Open Loop / Base, Power Enrichment, Temperature Control, Cutoff, DFCO, Lean / Fuel Saving, and Flex Fuel ). When attempting to turn off long term fuel trims, I have completely different fields. Being very green to tuning, I cant seem to differentiate what field would be the correct field to alter. I can only assume it may be under temperature control. If anyone has any valuable input on this, I would be grateful.
