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, considering only
needing 2 modules instead of 3.
