How Does AFM Get Turned Off with Edge CTS2 Programmer # EP85350 on 2016 GMC Sierra

Question:

I have a 2016 GMC Sierra 5.3L with a EDGE CTS2 Gas Evolution and I can’t seem to find the option to disable the AFM cylinder deactivation. What can I do to find this feature?

On your Edge CTS2 programmer # EP85450 press the home button and scroll down to settings. Once you are in the settings menu you'll be able to scroll down and see the option for active fuel management. If you don't see this option you need to update your programmer as this wasn't a feature always supported. But with current updates it was released.
