Speedo Calibration
Just picked up a set of 285/65R20 Cooper AT3 XLTs and Eibach leveling shocks to put on my 2021 F-150 XLT, but I’m guessing I’ll have to get the speedometer calibrated. Has anyone seen a calibration tool available yet? I saw someone mention Forscan may get updated to support the 2021 F-150, but didn’t know if speedometer calibration is even supported by Forscan.

From my research, you would use Forscan to edit your new tire size and that will calibrate the Speedometer through the main brain.
But since the 2021 Forscan tables aren't out...let alone a working version of Forscan for 2021 is still being tested, we won't know 100% yet.

Analog Speedo reads different than digital speedo and cruise display
2016 F150 Platinum. My Analog speedo reads about 2 mph lower than the digital speedo and the cruise display, and I have confirmed with GPS that the digital is correct. Is there a way I can use Forscan to recalibrate just the analog speedo?
