Tachometer with LASAR

[sabinof]

I am installing a LASAR system on a Lyc O-320.
It has a tach pulse output.
Which is the best way to feed tach information for the EMS 120: (1) connect the LASAR pulse to wire 32 (or 33) or (2) connect both 32 and 33 to the start switch P-leads?

Currently, there isn't an output that we know of that is compatible with our EMS systems. As far as we know, the tach pulse output is well below the 10V that our systems require. And the P-leads on those electronics systems don't have pulses on them like a normal mag does.

One thing that could work - either of the Vans tach generators on this page will work. It's been a good alternative for people in other situations where neither the p-leads nor an electronic output from the system has had a capable output.

Great, thanks. I'll order one of them.
