I know 18 degrees is the highest within spec but since we run 93 here in Alabama is it possible that I could go to maybe 19 degree's without worrying?

 

.....i'm at 21 degrees with spec B's - although that's prolly NO help at all.

I wouldn't advance too far without being on the dyno. Too much advance is bad for power just like too much retard. There's a "sweet spot" somewhere and the only way to find it is on the dyno.

 

I've run 20 degrees on 93 no percievable problems.

 

Good question. I wonder when acura decided on the safe range of timing, if they assumed the lowest high octane gas there is in NorthAmerica?

 

what do you guys think is safe octane for 18degrees timing?
89, 91, or 93?
right now im running 93, but just wanted to check

 

lol...

use 93 for 18+ degrees. if you can get more than 93 octane im sure you can advance the ignition timing some more.
