Mike, whilst it is good to see a sense of humour around here, selectively editing my posts to make it appear as if I said the opposite of what I actually said is misleading for others browsing the thread, as Michael's post demonstrates, and kind of dishonest. To be fair to others you should edit your post.
Michael, the comments quoted were preceded by In my view the basic misconceptions underpinning the above are: which rather changes the meaning.
Mike, your earlier engine mapping analogy isn't really applicable to the discussion as engines are not LTI systems. I used to design engine, gearbox and chassis management and data acquisition systems for motorsport applications as it happens, though that was 2 decades ago. One of the most interesting engine types to deal with is two-strokes, as a single misfire has a dramatic effect on scavenging efficiency and hence the crankcase mixture - the early two-stroke fuel injection systems tried a simple map-based approach which was disastrous, as misfires caused havoc. The solution there is to model the crankcase mixture, using crankshaft acceleration as an input to the model. If that doesn't count as off-topic, even in a thread of 7,000+ posts, I don't know what does 🙂
