My F-150 had the auto shut-off, but through the magic of an aftermarket tune, it no longer does that. And it also gained a good deal of horsepower too. But the big thing is the auto shut-off is disabled, and the transmission shifts the way I like it to shift, not the “economy at all costs” way that Ford had set it up initially. Still get 20-22 on the highway, not bad for a large 4-door crew cab pickup truck.
I think I can go in the settings and preferences and shut mine off so I’ll have to check. I don’t mind it idling down but shutting off is scary.
