Interesting,

Do you have pictures of this system?

I haven't heard of firing both plugs per housing at the = same time (most fire the trailing plugs independently and the leading plugs= simultaneously with a waste spark cycle). This sounds pretty good, conside= ring only needing 2 modules instead of 3.
