Flowtrecs Tacho Pulse Limiter (Inboard Version)

This version of the Tacho Pulse Limiter is specifically designed for carbureted inboard (stationary) engines. Stationary engines often generate ignition signals with high voltage peaks that can cause unstable RPM readings.

WARNING: Connecting a carbureted inboard engine directly to the fuel computer without this limiter may permanently damage the display unit due to excessive signal amplitude.

The limiter acts as a protective filter, stabilizing the pulses and ensuring clean data for accurate engine speed calculation. It is a mandatory component for the safe operation of Flowtrecs systems with older carbureted stationary engines.

For EFI/DFI engines, a pulse limiter is not needed when the RPM signal comes from a suitable electronic tachometer output rather than directly from the ignition coil. Select the connection according to the signal source; a direct coil signal may require a limiter to protect the instrument.

Main features:

  • Essential Protection – safeguards the electronics from high-voltage spikes
  • Dedicated for Inboard Engines (Carbureted stationary models)
  • Stabilizes erratic RPM readings
  • Ensures accurate and steady RPM display
  • Simple installation between signal source and gauge
