So i was able to pull up Forscan on a 2023 Expedition and saw a lot of common options to change just as a way to see what was in the database.
I ended up talking in person later to a ford tech at a dealership and he noted on 2023 and up Expeditions that alterations in Forscan could/have cause(d) the module to become bricked if the FRDS scanned the system. Something along the lines that the FRDS sees the modified value as a corrupt memory location from the factory default. The result would be to remove and replace the dead unit. Not sure why that would result in killing the module.
Is this just misinformation or something I should be concerned about? He also noted that backing up to the asbuilt condition prior to scanning would not cause problems.
Forscan has a disclaimer stating possible damage, just like many types of software.
As with any programming, whether it's software or firmware, there is always a possibility of causing a malfunction, ending in bricking a device.
I have many years of experience with firmware/software programming and modifications, and have never run into any issues that caused permanent bricking of a device. I "always" perform a complete backup before changing anything in Forscan.
You can find many sources to help you find what works and what doesn't. There are also several .pdf and .xls files available. In the past F-150, 250, super duty sheets are very similar for the respective year of Expedition. I use AS BUILT format whenever available.
From Forscan: "FORScan may support a limited set of functions and configuration parameters for brand new 2021-2025MY models (we work on it)."
