I've got some issues with my Dash 2: It is installed in a Westfield kitcar (Super Seven) with Honda CBR1000RR bike engine. The motor speed drops down to zero over 8.000rpm. The same with the speedometer: Above 70km/h the gauge drops down. Both issues are reproducable with different engines and ECUs (Megasquirt and stock Honda) and also with different speed-sensors at differing positions (wheel and propshaft). All other sensors (oil/water temperature, AFR, fuel) work without any problems.
Therefore I fear that it is about a hardware failure of the Dash. Does anyone know the phenomenon? Maybe there's a problem with the wiring after all?!

Please help.

I didn't find the right solution from the Internet.
