Displacement on demand

0 split definitely helps high vacuum stability. It also helps when running lean.

I want to justify driving my RX7 and it is hard to do when I get below 30 mpg around town with it and my Metro gives 50 mpg around town. If I could get DOD operating, I think that I could get 40 ish out of the RX7 which would make the difference livable.

RETed almost has be scared off because of his predictions of engine failure.

I don't run 14.7:1 while cruising, I run 16.2:1. I am running about 60 degrees of advance while cruising at -45kPA. You have to light the lean mix a lot earlier as it burns more slowly.
