I will throw in my two cents i have been actively using Forscan on 17 Fiesta ST
Here is what you can do with Sync 3
Themes: APIM (If you want an ST Splash Screen do not change 7D0-03-01.
7D0-03-01 xxxx x*xx xxxx
Visual Design Variants:
0=Ford Classic
1=Ford Timeless,
2=Lincoln Timeless,
3=Lincoln Next,
4=Ford New Blue GT (must also set 7D0-02-01 xxxx xDxx xxxx)
ST Splash Screen
7D0-02-01 xxxx xBxx xxxx ST Ford Performance boot screen animation
Climate Control (APIM)
1) Enable Climate Menu (This also activates the ability to speak to the car and tell it what temperature you want your HVAC settings to be.
2) Enable Climate Temperature Display that will show to the left of your outside Temperature
3) On mine i chose option 3. Our cars do not have dual climate but this is the only way to enable this.
7D0-01-01 xxxx xxx* xxxx
Climate Front Zone & HD Radio: 3=Dual Zone & HD radio avail, 2=Dual Zone & HD radio not avail, 7=Single Zone & HD radio avail, 6=Single Zone & HD radio not avail
Remove Sirius from Menu (APIM)
** Unless otherwise noted, below data is for SYNC 3 v2.x & v3.0
7D0-01-01 *xxx xxxx xxxx
Removes Sirius from audio sources (decrement your value where the asterisk is by 2; if you have an "A" make it "8", if you have "2" make it "0")
Instrument Panel Cluster (IPC/BCM)
1) Enable Fog Lights for cars that do not have them (non-st)
2) Disable Shift Light
3) Disable TPMS (for winter, aftermarket wheels, etc.)
4) Change Rolling Diameter (Useful for correcting speedometer with Aftermarket tire and wheel sizes)
Sync 2 Only
Add Navigation with nothing more than a NAV Card and Forscan to enable.
Here's what you cannot do for sure
1) Bambi Mode (Fogs stay on with High Beams) However one could use a relay harness without Forscan)
2) Global Windows up/down we do not have the necessary hardware in our USDM cars.
All of this was from me trial and error and using F-150 Forums and the F-150 Guides
