Thanks for the info and clearing up my confusion, I kinda assumed that most cars now could sense the higher octane and adjust. Most of the V6 accord guys don't get 91 for the extra mpg, more to prevent knock, advance the timing for the extra hp and for the boosted/built guys it really helps alot. I've only ran 91 once to clean out my injectors and noticed a slight better response but no power bump from what I could tell (Ass dyno).

Edit: Also stand alone ECU's are very rare/ non-existent for the accord so the octane bump along with the timing advance is beneficial for us.
