Electronics International CGR-30P - Manual (Page 73)

The LPF-1 is a low-pass filter designed to remove the high frequency spikes on the LASAR Ignition RPM
output. Without this filter the RPM readings on the CGR unit may display jumpy readings at various engine
RPMs. The LPF-1 should be installed between the LASAR RPM output and the EDC RPM input.
