no, the *only* thing it has to do is prevent engine damage from knocking.

You don't program it to run any grade at that grade's best advantage.
For example, where does that stop? Can I put avgas into my Hybrid and
the programming will "take advantage" of that?

It's designed to run at 86 octane. Yes, the engine management computer
will prevent damage should lower octane fuel be present, but that's
different from saying it will change the engine parameters for more
performance if higher octane is present.

It doesn't do that.
