How easy do settings get erased?

Post by ChiliGilly » Thu Jan 23, 2020 6:23 pm

I have a question that I haven't really seen the answer to anywhere... I have changed the speedometer hex value in order to compensate for different sized tires.

I am just curious how easy it is for this value to be reset. What I mean by this is, will software updates to the Sync 3 system or any dealer ECM/BCM flashes reset this value to stock?

Edit: vehicle is a 2019 f150
