Speedometer recalibration locked by Ford!?

[klvanzu]

My dealership is telling me that they cannot recalibrate my speedometer on my 2022 after installing a lift because Ford has locked out that ability. This makes no sense to me and I haven’t heard this anywhere else.

Has anyone had issues with this?

I recalibrated mine after increasing the tire size by using Forescan.

Well you wouldn't recalibrate your speedometer just because of a lift, it would be a change in tire size or axle ratio that would trigger the need to recalibrate.

I'd say find a different dealer to work with, cause that sounds like some BS there, or get a hold of Ford customer service and get the real answer.

If you can get that in writing, just forward any speeding tickets to the dealer/ford to pay since they refused to correct the speedometer.

The dealers have stock settings for the different tire sizes and gears sold by the manufacturer. If it is a different height tire then there is no factory setting to select. I had the same problem with my GM truck.

The change with my new tires was 4% so at 50 mph on the speedometer the truck was traveling at 52 mph. No big deal to mentally remember that at 70 mph the truck's speed was actually about 73 mph.

Yep, changed tire size so now speedo is off 2-3 mphs depending on speed.

Ford confirmed it's not possible to change it but the forescan crowd has found a way.

Dealers can’t, but you can with forscan. Super easy

You have got to be shitting me. That $1000+ tool the dealers use can’t adjust the speedo for larger tires….wow I guess forscan may be in my future after all.
