Right, but my understanding of those was that they were generally industrial engines, tuned for a constant speed and with well known projected loads. This application would be a lot harder in my opinion.

Point of fact: a true Atkinson has a funky conrod arrangement that makes the expansion stroke longer than the compression stroke. Strictly speaking, modern "Atkinson" (or as I call them, Atkinson-ish) engines fake the effects with cams. A true Atkinson wouldn't have the contraflow effect that bollixed the sensors.
