[Diy_efi] Timing Advance Curve?

[A6intruder]

Octane has everything to do with the speed of burn.  Higher octane actually
controls ping by slowing down the burn.  This is why a very low HP/cubic
inch engine doesn't necessarily gain power with higher octane.

Huh ?

WHat has octane to do with the speed of the fuel burn ?

Isnt octane a measure of the fuels ability to resist knocking ?
