2018 Fit: will ECU advance spark if I burn 93?

Owner’s manual says “87 octane or higher”. Will the ECU advance the spark if I run higher octane fuel, like 93?

Yes the computer relies on the knock sensor for timing advance. If the octane is higher it harder to cause detonation so the advance gets higher before the knock sensor activates.
