What you described sounds like it may be a bad sensor circuit. If the speedo has a sensorless mode, try that if you haven't already. Might at least get you going until you get a new speedo.
Either the LRP SXX TC Spec or the HW will both work with that motor. Actually running a V1 TC Spec right in my Sc10 4x4 and it's been great with both SC4X 6.5 and 4.5 motors. Have been running HW/SP in other crs for almost a year, very happy with it. Like Sym, I prefer the SP software, and it's also easier to find setups for. If you can find the HW/SP 120 amp 2.0 Pro, that's the best speedo for 4wd SC. Lower turn limit than the 2.1, but may be hard to find.
