Hi All:
I just bought a set of factory spec 37s for my 35 truck. I'm trying to find the right code to reset the speedo in Forscan. Would anyone with a 37 truck care to share what their truck shows in the following sections:

BCM line 726-15-01
BCM line 726-15-02

Thanks!

Yup just did it this way a few days ago, worked perfect. Confused why some people were talking about entering tire circumference when you can just do it this way.

Bumping an old thread, but did you need to do anything to reset the PCM / TCM?
