Other than that, I have personally replaced a MSD CDI system (6AL) with LS2 coils with a significant reduction in misfires and power increase of about 15 Hp (400ish horsepower N/A V8).

Strangely, I too found the CDI to misfire significantly more at idle (as TTT found).

All I want is enough ignition energy to light the air/fuel charge in my Naturally Aspirated Rotary until the VE decreases to the point that I might as well stop. I am expecting this to be between 9,000 and 10,000 RPM. I am reasonably confident that 120mJ of ignition energy will get the job done.

If every car was a Ferrari, I would be walking to work.

I just want something that is functional and inexpensive.

The LS2 coils appear to fit the bill.

I hope they do, because I have installed them on the car and will hopefully be starting it this weekend.

Another type of ign I have been trialing from Japan is ULTRA CDI's, Mazda factory use them on most PP set up's they are working well.

CDI really is the best, though I suppose some type of inductive could be made to work, but I doubt it will ever be on par.

If you have access to a scope I'd like to see how much current, secondary kV, and burn time, you get on your system.
