Pmag experiences,combined threads

Hi Joe,
I am (wrongly or rightly) going to read into your replies and assume (I know, I know) that you are not going to call back Emagair out of principle. Your point is that you want a call back, not to have to call them back...again.

But, maybe they are really busy after just being gone for several days and are assuming that your problem isn't severe because you haven't called back. I don't know what the message that you left them states, but why don't you just call them again and explain your dissatisfaction. It's a win-win for both you that way.

I actually feel compelled to call them on your behalf and tell them to call you! ;-)

False. I have called them more than once each day. I leave a message each time. I will be calling them again shortly today. Again I will leave a message.

If I don't have some form of satisfaction by the end of tomorrow, PMAG will be history in my life. I need my airplane back in the air, not sitting on the ground waiting for a call that may or may not come this week.

It sounds like you'd be happiest if you ditched the PMAGs for slicks/bendix/etc. mags right now. Why wait?

Great idea. Thanks. Very insightful and helpful.

Emagair has contacted me. We are working toward a solution.

[N131RV]

Quite helpful, once contact is established. I will be doing (as stated before) the full troubleshooting guide. Emagair will be sending some parts to help the process.

Thanks to all who were helpful.

If you don't like your Pmags, you can give them to me.

Thank you for the free, helpful advice. I'll take it under advisement.

Actually, I called Brad for you. He had been sick. He agreed that he needs to be more accessible and said you had a valid gripe. We even talked about things like him getting a smartphone with email access. I hope you figure your problem out. I've been running P/Emags since 2005 and I love them. As you heard there were problems in the beginning. I know because I lived through some of them but now they seemed to have matured. Starts easier, runs better, saves gas, and now I think the are at least as reliable as a mag. Good luck and I'll still take them if you want to give them away.

Spent the day checking wires, plugs, connectors, etc. All four wires ohmed good. No shorts or opens. Connectors are made correctly and seated correctly.

The 6 pin and three pin connectors are firmly seated in the Pmag. The ground is good.

Checked pmag mount for tightness and retimed to TDC using the "puff" method.

All plugs good.

Symptoms:
Engines starts great, idles smooth, runs great up to about 2000 rpm.

Around 2200 rpm, the engine starts missing (a little).

At 2500 rpm, the Pmag begins cutting in and out badly, sometimes dropping 300 rpm before catching again. It's a scary sound.

Sometimes only stumbling a little. Occasionally backfiring. Cylinder temps and EGTs remain pretty even (no cold cylinders). Possibly (and it's not definitive) a small temperature drop on #3. So slight it's hard to really tell.

I really don't think it's a plug or wire at this point. All 8 plugs have been changed. All 4 wires have been checked. I'll have a complete new harness kit tomorrow and I'll remake all four plug wires just to be sure. If it is a plug wire, it's not like any plug wire symptom I have ever seen before.

It really feels like the coil is cutting in and out under load. Just a WAG.

Brad has been most helpful. Kudos.

P-Mags (and other electronic ignitions) will fire a normal car timing light (induction pickup). Easiest thing in the world to have one guy run the throttle while another watches the timing behavior. Sounds like it is over-advancing.
