This symptom sounds like a spark timing difference between the two. If you shut off the retarded mag, you would see very little RPM drop, whereas if you shut off the advanced mag, a substantial RPM drop would be observed.

Just a guess...

Default I think that is almost right

I think I understand walter, but that is not exactly correct. It is true the P/E-mag can be set in a fixed advance mode. but the Lightspeed can be advance can be adjusted from the cockpit if you connect that option. Cheers George

Default yup, agree.

I believe the guys at emagair are moving in that direction as well. That will be a nice feature. And when they provide a method of integration with
my EFIS that will be nice too. I would like to see the advance in action
and the effects on CHT.

Unfortunately, the lightspeed system has no mag-"like" backup function
in case you lose all power and the battery is dead. I'm not about
to say one system is superior to the other, just stating the obvious.

Ain't it great to be flying right when all this new fangled stuff is here or
on the near horizon. I'm amazed at the creativity these folks have.

Default E-Mag endeaver

I made the comment that you guys did not won't to experience the problems that I had with the new E-Mag P-Mag. That statement still stands.

I received my Mags about two weeks ago. They were the new ones that were recalled. I installed them and flew with them before the problem was discovered. The advance code was wrong and they were advancing to far. Caused some serious heat problems. I sent them back and Brad reprogramed them and sent them right back. I flew with them today and everything worked fine. I ran them today at 26 deg advance. Tomorrow I will work my way back up to full advance and see what happens. You can run them at 39, 34, or 26 deg. If you put a switch to your jumper you can change from 39 to 34 on the fly.
For you guys that haven't installed your mags yet, here is something that I wish i had known about before i started. After you get your mag timed and you stab it, you won't be able to see the timing lite on the mag because it is on the back side. There is a space between the front and back half that is about a 1/4 inch. If you look through the space you can see the light real well. Hope this helps.

Just got an email from UPS. Mine are "in the mail." The big brown truck should deliver them to a random house in my neighborhood some time next week.

Just to update an old thread...

Received my Emag/Pmags a few days ago, July 19. Ordered on January 23... according to my math, that's right at 6 months. Ouch.

Although they say production/delivery dates are speeding up, if you're considering E/Pmags, order 'em early!

Just got a call today from Mattituck saying my engine was ready for shippment. It had been delayed for an E-mag and a P-mag which were ordered in the first half of March. So, that appears to have been a 12-13 week delay.

These delivery times may not be representative of today's expectation as they may have just got caught up with their backlog.

Or, maybe it is.

They were producing them in batches so the wait could be several months or a few months. Not sure if they're still doing that. The last time I talked to Brad his goal was to finalize the design and then mass produce.

The flip side is that they don't rush shipping them out. They make sure they get them right. Many people are flying with the E/P-mags with good reports. That's more important than shipping delays. (He says now that he already has his P-mags. )
