It is much simpler than that diagram.
The only inputs it has are, 12 volt power, ground wire, 1 injector signal and the PVC valve unit, itself.
The rpm and duration of injector signal can yield 2 data points.
As far as Air flow meter, exhaust, etc., nada.
Those may be explained in the verbiage. They might be described as points and data used to evaluate the effectiveness. I have not read the patent. But, I agree, nothing wrong with simplicity.
However, it makes it easier to copy - just outside of the patent.
Regardless, if Serge can consummate the Chinese deal, I believe we just might have a good year, finally.
Good Luck to us!!!
