The speedo got very hot (a lot more than my old TC-Spec one), and definitely
hotter than i expected.

I ran mod, 4 Turn Speed P. V3, Roll-out was 35 mm.
Speedo settings were 1/7/3/0, i wanted to start with the (from LRP) recommended settings.

I will next week switch to 1/7/0/0, i.e. no timing, and see if this works better...
