Speedo calibration on a 2017 f150

Is this something I can do in HP tuners? I know in my gm files I can pull open the edit section but the tire/gear adjustment is not in there. Can I do this in the speedo part and change the driven circumference, min and max? And what calculation do I use to get the correct numbers for the values if so?

Hi Jeremyt,

I suggest you look at downloading Forscan for Fords and do you speedo adjustments from there.. its easy just need to read and make sure you dont screw up the numbers
