High compression and forced induction introduce their own complications. High pressure (along with heat building up in the engine) can cause the gas to combust before it should.

Lower octanes at higher altitudes when used in carbonated engines allowed them to run more smoothly higher up because lower octanes leaned the engine out preventing the flooding effect......In older engines the running of too high of octane at really higher altitudes can and did cause engine damage like the burning and melting of valves & pistons. In older engines' without complex ecus they could not adjust the fueling to lean the engine out so lowering the octane was the best option.
Why do higher altitudes not need as much octane as lower altitudes?
