Yah Dahwin! I think I scared them when I polished off that 74 ounce prime rib though!

1:1, I am not sure what the most common mag failure might be but the ignition system only enhances the mags performance by boosting the spark. Any failure of the G# system would result in a failure of the boosted spark, not the mag function.

So in a nutshell, the G3 ignition system is just as reliable as any good old fashioned magneto (and they are pretty darned reliable)!

Does that help?

kelly- most people don't say what exactly failed, just that it stopped working. one poster from this thread:

http://www.vansairforce.com/communit...ht=mag+failure

said everything was rusted inside. hope that helps somewhat


also look at post #20 on this thread:

So there is not variable ignition timing with this system, right?

Bugsy, That is the way I understand it. The spark is more "intense" and longer in duration. It uses the mag as a trigger.

The technology is borrowed from the old hot rod style Mallory ignition. It does for magnetos what it did for hot rods before electronic ignition became standard equipment in autos.

Small point, it is not based on Mallory ignition stuff but rather MSD, it uses either a MSD 6A ignition box or he has one which has the MSD module built into his interface. MSD is extremely durable and well tested stuff. Much better than Mallory, yuk!!!

YES!!!

Thank you!

It IS MSD, not Mallory!

Sorry!

CJ

Thanks CJ and Danny. Basically what I feel is that an EI is generally lower maintenance (maybe an incorrect assumption) than a mag, which equates to "more reliable" (again, maybe incorrect). So with the G3, it's nice that it reverts back to a standard mag function if the EI fails, but it seems more likely that the mag would fail, possibly making the eintire system only as reliable as the mag I guess there could be some mag failures that the MSD could mask or work through, and others where it takes out the whole system?

I really like the concept, I guess I just need to edumacate meself on it more thoroughly

It only uses the points in the mag for a timing signal when operating in G3 mode, so I expect that the points will actually wear less, as there is no arc generated across the points as they open.

I have one now, and it seems to be a pretty good system, and it definitely improves the smothness.

John,
Have you seen an improvement in fuel burn? My buddy and I both spent a lot of time at their booth at Oshkosh last summer and were both impressed with the static display. He is going to put one on his Cozy MKIV IO-360 this spring. Just wondering if fuel burn would be a little better.

Perhaps P-Mag stray a bit from this format with their integrated coil unit.

Funny but E-mag removed all the $3 wires and $40 sensors and put them all in one unit and you don't like it?

Their early failures were attributed to two things, the sensor magnet mount and a lost timing mark under certain conditions/configurations. Those two things were resolved a year and a half ago. Since then many hours have been flown behind these things without any issue.

The best part is their customer service. When I had my prop strike all they charged me was shipping there and back, $65. For that they tested both of my P-mags, disassembled them and tested the components, reassembled and tested them again. All that and they found nothing. Try getting that kind of customer service from some of the other EI vendors.
