Dear Andre, no it´s not possible, because the Volvo Penta D2-55 has a own Bus-System between MDI-Box and RPM-Gauge. Your SVB-team.

Technical question
Darius V.
| Aug 7, 2020
I can not get this thing to operate properly. I’m trying to mate it with Yanmar 3HM35. Connected according to the instruction, which came with the unit. When the engine is started at idle (roughly 500 rpm), tacho readings immediately go to 4000 rpm, which is complete nonsense. Entering the setup regime and decreasing the ratio from 10.0 to 1.0 does not change anything. When the engine is stopped, the readings go to 0, which indicates some kind of sensitivity to the tacho sensor. The sensor is checked to provide a nice meander of 0 to 12 V. The frequency at idle is approx 1kHz. Changing engine rotation speed does not change the readings. I want a good advice or my money back.
