Innovate Motorsports LM-1 RPM Converter (Aux. Input Cable 2) - Manual (Page 6)

5. Setup of the RPM-Converter for different rpm pulses/rotation
During the setup procedure the RPM converter measures the number of pulses for 5 seconds.
Then it selects from a table the closest matching engine setup. If the measured pulses cannot be
found in the table, the RPM converter retains the previous setting. The table covers the following
engines:
# of
Cylinders
Type of
Engine Pulses/Crank
Rotation Notes
1 4 Stroke 1/2
1 2 Stroke 1 Or waste spark ignition connected to one
spark wire or coil
1 Rotor Rotary 1
2 2 Stroke 2
4 4 Stroke 2
4 2 Stroke 4
5 4 Stroke 2 1/2
5 2 Stroke 5
6 4 Stroke 3
6 2 Stroke 6
8 4 Stroke 4
8 2 Stroke 8
10 4 Stroke 5
12 4 Stroke 6
12 2 Stroke 12
So the table consists of engine/ignition types of:
1/2, 1, 2, 2-1/2, 3, 4, 5, 6, 8 and 12 pulses per crank rotation
