REFLECTOR: RPM SENSING

[Dave Dent]

don't remember. It's been to long.  It wasn't worth it at the time.  I was also using a Rocky  Mountain monitor as well and it worked fine.  I wanted to see the advance more then any other anyway. That read OK and after watching it a number of flights I didn't pay much attention to it.  So there it sits neglected, the poor thing. Ha.

  Thanks Dave ... I believe the "extra small" monitor you are talking about gets its reading from the RPM voltage output (from the output connector, Pin #2).  Did you ever check the "Pulse Stream" (on the input connector, Pin #6) for accuracy?

  We have been using the LSE dual system on the Cozy and the output comes from the computers not direct from the Hall Effect  or the direct sensor.  So it don't mater what pickup you use, you can get it.  I don't like the LSE for any output other then ignition though.  I bought the extra small monitor from LSE for the system and the RPM does not read right or the MAP from the computer.  Klaus says that you have to convert it related to the MAP.  So I dropped the whole thing to be reliable, for any kind of data output that is.  I check the output with a tach checker and direct reading MAP sensor.  The gauge just goes along for the ride now.

    Anyone using an LSE Plasma II Electronic Ignition? If so, maybe you can answer this for me:

     

    The Plasma outputs a "pulsed signal" to read RPM on an electronic tach or EFIS unit. Does it work with the direct crank sensor on a 6-cyclinder engine? Or do you have to use a Hall Effect sensor for the pulses to work?
