The other thing I should have made clearer is the Honda F1 engine is very unique in the fact that it is almost a GCI engine. The plug starts the ignition process, but the outer perimeter top of the piston ignites mila seconds after.

I have to be very careful in what I write here because I do have some inside information that could get me in trouble. What I can say is some carbon build up is needed at high load with extreme cylinder pressure. The other thing is a Passive Pre-Chamber can increase heat in the cylinder or decrease heat in the cylinder. During light load FE mode, I want to keep the heat in the cylinder due to very lean conditions the combustion temps drop off drastically. The heat helps with keeping the fuel in gas form and I need the exhaust heat to stay up for the hot side of the turbo to work in its optimal area in FE mode. Now in high power mode I need the Pre-Chamber to pull out as much heat as possible.
I can think of a couple of reasons to have a carbon layer on the piston, head, valves.
Not sure if I should or want to talk here now..?
Sounds like you can neither agree nor disagree with what I say anyway!?
