2012 Chevrolet Silverado AFM dissable

[Pellonor]

Hello;

I purchased the InTune I3 wih the understanding that I could use it to shut the Automatic Fuel Management system off in my truck. Do I have to get a custom tune to do that or did I mistake the purchase of this unit.

its in the modify parameter menu after you select the tune.
set AFM/DoD to OFF, save it, then back up and apply the tune.
