How to: Recalibrate Speedometer with Forscan for 2021 Bronco

[FranklinCounty4Door]

Has anyone updated to Forscan 2.3.46 which was updated on 2/7 and tried the PCM relearn?

I just used 2.3.59 and the OBDLink EX and was able to clear all codes using the guide on pg8.

Here's a quick, informative vid on doing the recalibration.

Just another testimonial . . . same version, same scan adapter, same successful result. PCM and AWD module DTC codes cleared without issue.

Switched out 315/70-17 OEM Territories to P285/70-17 Cooper Discoverer AT3 4S, used 2525 mm (was 2653) circumference (Thx um . . . @Tricky Mike ?)

As another data point, mine was factory set at 2525mm with 285/70/17s. This sounds way too small for 315s but I'm not arguing with what works.

and 35 psi (was 39 psi) TPIM settings. Speedo reads 1 mph over GPS reading, perhaps due to minor differences of LT vs P-metric spec. I'm good with it as is.

Took me a little while to get comfortable with maneuvering between screens, but once I figured it out, it was easy. Be patient, and backup the factory settings FIRST! Speakers are next, I appreciate the 6G community for such an informative and valuable resource.

Dick is dead to me, nobody liked that guy anyway.

I think the digital speedometer is programmed to read 1 mph over. It was a consistent 1 mph over from 0 to 85 stock and it is the same reprogrammed for my 285/70 17’s (replacing 265/70 17’s) on my Black Diamond.
