Connecting the RPM signal
Reading RPM from the ignition signal of a carbureted petrol engine requires an additional Tacho Pulse Limiter. Two versions are available: IN — for inboard engines and OUT — for outboard engines.
For fuel-injected engines (EFI/DFI), a limiter is typically not needed when using a suitable electronic tachometer output.
The limiter is used only for RPM readings and is not required to measure fuel consumption.
