Does the ECU adjust quickly to octane change?
I was wondering how long does it take the ECU to adjust to a higher octane, say when I go from 91 octane to 93 octane? I asked this question in another thread, but nobody answered it.

It depends on how sensitive the knock sensor is.
Without datalogs, or a dyno, it's difficult to say. |
