What is the mission statement for your ignition? Figure that out and then you can see if the emag aligns. If not, find another product.
You want a quick and dirty? Pmags will often give better performance than magnetos, but have similar (or increased) maintenance requirements. But they have a fixed ignition curve which may or may not suit your engine or how you operate your engine. More modern ignitions offer far more flexibility and versatility which will almost certainly fit your mission.
But Homework is required.
I did not choose Pmags based upon all of the information posted here. I chose a more reliable and more tunable solution similar to the SDS system. Another vote to do your homework first.
