We should all be so lucky..... (That our kids at 18 don't think we're a J/A, )

So I have a question:
I know on my enthusiast-level Durametric tool, there is a tab for the cluster. I haven't explored it whatsoever, and I'm not where I can anytime soon. Does anyone know if that function / tab will allow changes like speedometer calibrations? My other "Tuner Tools" (think SuperChips) allow for this, but that's a different sort of functionality.

waddy'all know?
