Six cylinder pMag - flying

[Aerosport1]

Just to give some more info on the E-mags for the Lycoming 6 cylinders. I installed the updated version about 10 days ago. I removed My left Slick mag with Impulse coupling which was running all my lower plugs. I also changed from aircraft fine wire plugs to iridium fine wire auto plugs. My right ignition is a Lightspeed plasma 3 which runs great and has been on my plane for almost 900hrs and 10 yrs. This change took me about 12-14hrs. Setup And timing was pretty simple. So far I have about 2 hrs time on this setup and so far very happy and glad to replace the Slick. I did change plug heat range from Denso IK27 to NGK 8 or Denso 24 this helped on some test I was performing that were recommended by Brad at Emag. So far performance is better than the Slick when doing test where engine is running on just left ignition. Running as normal there is not much difference than the Slick. EGT’s and CHT’s seem very good in all conditions with the Emag. I think my fuel burn when running LOP at alt 9k is maybe .1-.2 better
With same TAS and cruise settings I always run. Time will tell once I fly a couple
Trips. As of now I will call it about the same.
Overall at this time I am very happy with my change.
FWIW

Maybe I've missed something. Are the 6 cyl p-mags available to the average Joe yet? I'm wanting to replace my other mag with something other than a Lightspeed.

I ordered my -540 on August 3. I spoke directly with the Lycoming factory around 8/10 to confirm a few details.

Lycoming is currently testing a p-mag but has not approved it for delivery from them.

Current wait time for a Thunderbolt 540 is estimated at 7 months, and the Lyc rep I spoke to thought that by the time mine gets built, a p-mag will have been approved by Lyc, assuming it passes all tests.

SDS has had a 6 cyl EI out for a long time. http://www.sdsefi.com/cpi2.htm

I've looked at SDS too, but really like the self-contained features of the pMag. I really don't want to add an extra battery and/or a second alt to run a second form of electronic ignition.

Give them a call and order the pMag. It made a significant and measurable improvement in cruise efficiency in the RV-10.
