Default EMag or PMag?

Well, every time I call them PMags, I get corrected that the new ones are all the same and are called EMags. I don't know why, when they went with offering only one model, they decided to change the name of the one every one wanted (PMag) to the one they were discontinuing (EMag) Very confusing.

At any rate, the ones I am referring to are new and are self powering above 800-1000 rpm. They are EMags that used to be called PMags

Just like " the artist formerly known as Prince" maybe these should be " the mags formerly known as PMags" or "TMFKAPMag". Then again, that looks like it could be the name of an erupting Icelandic volcano never mind...

All best

Jeremy

Jeremy,

The company is called E-Mag Ignitions. At one time they sold both an E-mag and a P-mag.

The P-mags have always had an internal generator capable of powering the ignition, should they lose ship?s power.

The E-mags were identical to the P-mags with one exception; they did not contain the internal generator.

The original idea was to install one P-mag and one E-mag. That way, in the event of an electrical failure, you still had one self-powered P-mag to get you home. What they found was that most people, myself included, paid a little more and installed two P-mags.

E-mag Ignitions stop production of the non-powered E-mag a year or two ago.

In simple terms, the company is E-mag and the ignition is a P-mag.

I understand the history and the specific differences in the models. I've been following them for a while. I suppose I let my frustration with what I consider an unfortunate change in naming convention come through. This discussion is serving to highlight exactly why I think it was an unfortunate choice. For the sake of absolute correctness I checked their website again it looks like the official name of the mag model I have is:

P114-L4

In my book that would make it an EMag P114-L4.

While they refer to the P model, I cant find the word PMag anywhere on their website anymore. Only the P114 model from the company EMag.

But I would agree: it SEEMS like they should be called PMags I did as you did Bill, and have two PMa...er two model P114's

All best

Jeremy

Default PMag

I have 260 trouble free hours on dual 114 P-Mags. Irridium plugs. RV-9, 0-320, 150HP, Mogas.

Planning to get one of Bills controllers when he sells enough of them to lower the price ;}

I guess you would recommend the iridium plugs? These can't be gapped - correct? They just go in and run and run.....? A friend has them in a dual lightspeed system and that's all there is to his. Been going for several hundred hours.
Thanks!

Default PMag- Iridium plugs

Iridium plugs can be gapped like others. I have not had to gap them.
Yes, they seem to run for ever. Have used wire electrode platinum plugs on Rotax engines for years. Iridium is harder and is supposed to last longer. Also gives a hotter spark.
Here is a web site with lots of information about them
