Traded in the 5.0 for this 2022 3.5 Ecoboost. I test drove new ones as that was the plan but found this one with 2000 miles and got a good deal so it’s mine. When test driving the newer 3.5 they were pretty dam quick and torqey when throttling in. The one I picked up seems a little laggy and was thinking it has some adaptive learning into it from the previous owner. Would like to reset it. I asked the dealer but they declined. I have Forscan from the previous F150, wasn’t sure if there were was a way to do it through there or should I try a different dealer to reset it?

Or remove neg battery cable for 10 min i heard that resets learning as well
To be honest I would like to do this if I knew it wouldn’t mess anything else up. You are essentially draining the entire computer system of all memory. I have also read posts that some people have issues just changing a battery out. Technology can be so awesome but so temperamental at times. Just would like to try this as there is a pretty significant difference between the seat of the pants performance of the new trucks I test drove vs the one I purchased that was used (3000 miles). All the same year.

If you take the battery disconnect method, I'd do it overnight. Longer times period.
That would accomplish a KAM reset, transmission adaptive tables, battery management system, TCU and Gateway modules.....

Basically a soft/hard reset to its birthday.

And I don't believe there's anything to fear personally. Just know that it might behave a little confused for a while, no differently than it did on mile #1 the first time.

Nice truck, another thing that might wake it up is some fresh premium fuel. The engine will learn as it run how the fuel load responds to timing and boost. It will adjust timing and boost accordingly and put a correction factor in. If it’s lower quality gas it will feel sluggish.
