Display Speed Limit in HMI (2021+) is a lower-risk, convenience-oriented change for 2021–2026 Ford F-150 trucks, applied with FORScan over an OBD-II adapter. Shows the current posted speed limit on the Sync display. It is fully reversible and typically takes about 5 minutes to write once your worksheet is in hand.
The change touches the Accessory Protocol Interface Module (SYNC) (APIM), and your F-Config worksheet lists all 2 as-built code rows with the module, address, and target value. Each row includes a blank for your original value so you can back up before writing changes and roll back later. Posted speed limit visible on screen while driving.

How you'll apply Display Speed Limit in HMI (2021+)
The DIY process from start to finish — backup-first and, where possible, reversible.
Back up your originals first

Write the worksheet values
Enter the 2 target rows from your worksheet one at a time. Most owners finish Display Speed Limit in HMI (2021+) in about 5 minutes with a laptop and a FORScan-compatible OBD-II adapter.
Cycle the ignition and verify
Turn the key off and back on, then confirm the change behaves as expected before moving on. If anything looks off, stop and compare against the originals you recorded.
Roll back anytime
Because Display Speed Limit in HMI (2021+) is fully reversible, you can put every original value back later and return to stock whenever you want.
