Do I need a Signal Filter, or a High Energy Ignition Signal Filter?

 

Signal Filter

 

A tachometer filter transforms poor, weak or disordered pulse signals and corrects them by stripping out leading or trailing pulse signal interference.
Some such systems include, but are not limited to the following:

  • Single coil ignition systems
  • Point style coil ignition systems
  • Historic vehicles with vintage electrical systems and components
  • Vehicles with weak, strained or stressed electrical systems

 

HEI Signal Filter

The H.E.I. Tachometer Signal Filter would be required for an accurate reading on vehicles using a High Energy Ignition System.
