Instructions on how to use the program, exact settings for many behaviors, and a tutorial showing use is available on the first post in this very long thread (24,000+ posts):
https://www.f150forum.com/f118/forsc...ispreloading=1
The above thread also has users who will give assistance and answer questions. Program can also be used to change features on other Ford vehicles, though I don't have links to get settings for other than the F150. The thread above is for 2015-2020 trucks, there are similar threads for the 2021 and pre-2015.
One critical recommendation - as specified in the tutorial, BEFORE making any changes to your truck, make a backup of ALL of the module settings.
The program and adapter are also useful for diagnosing issues with your truck. It can read and reset diagnostic codes (dtc's).
