Basic/Load Settings > Tacho Output Dialog box has options for
Speed
Can be set to one of two options:
• Normal – an output pulse is generated matching each cylinder event, i.e., 4 cylinder engines have 4
pulses per engine cycle;
• Half speed – output runs at half speed. This can enable a 4-cylinder tacho to be used on an 8-cylinder
engine.
Probably the most common conversion is to drop a V8 where a 6 cyl used to live.
leaving a 6 cyl Tacho in the dash
Could a third option be added to Speed - 3/4 speed - output runs at three quarters speed. This enables a 6-cylinder tacho to be used on an 8-cylinder engine.
