A few questions...

So if the vehicle in question was designed to run most efficiently on 87, does that mean the high octane table is actually 91 octane? Or just anything higher than 87? What about the low table? How does the pcm calculate the octane level in the gas? A knock sensor just detects knock, right? What is knock? Pre-ignition or detonation? What's the difference? Do we really care about the octane level? What does the pcm do to adjust to oxygenated fuels and seasonal blends?





Any ideas?

Hahaha Bandit I wonder if this will turn into a big debate again! One could write a whole book (or at least a chapter) on those thoughts.
