Engines w/ knock sensors & octane rating
Not sure where this belongs, move if necessary.
I have a question about engines with knock sensors & gasoline octane rating.
Has anyone experimented with different octane ratings on engines with knock sensors? Would the higher octane rating stave off knock, thus allowing more advanced ignition timing?
The Wife's Hot Rod has an engine with equipped with knock sensors that will change the ignition timing if a knock is detected. It also has Displacement on Demand, I haven't got a clue as to what parameters are used to turn it on & off. It seems to run fine on 87, but I'm not sure I would notice a difference due to the electronics.
What are your thoughts?
Don
