You should only connect 1 RPM input (MAG or Electronic) If you have one mag and one electronic you should use only the MAG input. As long as the mag is still turning you will get displayed RPM even when it is off.
You need to disconnect pin 33 or it will not work properly.

Thank you Rob that was exactly the answer and explanation that I needed.

I was hoping the software would allow me to alternatively select. Since I want this option in the future, I will install an in-line switch to to pin 33 for now.

You do not want or need a switch. If later on you decide to add a 6 Cylinder PMAG you will need to disconnect the RPM sensor and then you will connect the Electronic input to only the PMAG, and yes the PMAG will drive the RPM display even when it is off for your light speed side. We do not want a wire connected to Pin 33 and floating at the switch acting like a big antenna, you will get noise on your RPM display if you do this.
In my airplanes I have the following:
RV-4
1 Slick Mag
1 PMAG
The RPM input is tied from the PMAG to the Electronic RPM input Pin 33
RV-10
1 Slick Mag
1 LightSpeed
The RPM input is tied from our RPM sensor in the Mag to RPM input Pin 32
In both cases the RPM display works perfect on RIGHT / LEFT / and BOTH
Call me on my cell if you need further assistance.

Rob,
This is a little off subject but,
Had it been available when you were building the -10, would you have used the P-mag instead of the Lightspeed? They have committed to having it available by the end of the year for the 6 cylinder.

I can tell you I just pulled both Lighspeed II+ ignitions off of my 8A after
400 hours and a string of problems and replaced them with P-mags. I now
have 100 hours on the P-mags and I'm very happy with them.

I almost waited for it and put it in mine. Good thing
I didn't....I'd be 550 hours less in the air, over the
past 3.5 years.

Having the P-Mag available by the end of the year and having it bullet
proof are two different things.
There are some real early adopter horror stories with the 4 cylinder
P-Mags from years back. I personally would not put one on my plane till
there are many success stories. I definitely would not place two on my
-10. It's one thing to experiment on your plane it's another thing to
perform R&D for someone's business.
All that being said I am sure they gained a lot of experience with the 4
cylinder unit and many of the issues are probably the same when up
scaling to a 6. I think it's probably cheaper to put two mags on your
plane (as I did) and wait till an alternate system is proven and right
for you. Then pull off one of your perfectly good mags and sell it at a
discount to another builder/pilot that needs a mag. That way you are
going form proven system to proven system.
Just an idea,
Robin

Yep, and they still don’t have the best reliability. Although I think I remember reading something about an e or p-Mag being offered on one of the Cessna models, probably the Skycatcher. The reliability issue is part of the reason I went with Lightspeeds, they have a very good track record and have been around for more than 20 years. eMag’s big news on their site is that they haven’t had a firmware fix in a year. Don’t get me wrong, I think they have a good idea and a good product, but I don’t think they have a good record of reliability. As always I would recommend anyone thinking about any of the different ignition technologies do their research. Each has their own pros and cons and I think e-Mag will be a good choice, after a few years of trouble free performance.

I talked to them at Sun n Fun this year. They told me that they are certifying the 6 Cyl. P-Mag and that is causing longer delays. They told me they will still sell an "Experimental" version, but did not want to release it until the certified unit is released.

It’s sad to say but reliability from any ignition vendor has taken hits, some more recent than others. Mag, pmag, lightspeed, or otherwise. With the recent crap from Slick a while back I’d caution anyone feeling overly comfortable with their choice of ignition. I’m planning on two mags myself. Here’s hoping that the shit parts are over and done with by the time I need to order mine. Heck at the rate I’m building lately maybe the 6 cly p-mag’s will be out and bug free!
