John,

I use the signal from the primary Lightspeed unit to the tach line on m= y VM=20 EPI 800. Here are some notes:

1. Lightspeed issues 2 pulses per revolution. Modern VM computers= =20 have a jumper to account for that option.

2. The pulse must be controlled by a diode and resister. I will ha= ve=20 to go to the airport for the diagram.

3. If you have a dual system, you might want to use a switch to set whi= ch=20 ignition is feeding the rpm input.

I know there is more info some on the LML since I did a complete report= on=20 the install back in 04 and 05.

Maybe someone else has better info.
