you could get an ignition computer... but that's not just using the select mon

i have no problems running the car on 93, and the ppl in calif run on 91 or lower, so i think that 93 should be fine w/ some advance

and my guess as to what it does with the advancing in conjunction to subaru's knock computer, is right now the ecu will advance it continually until it senses knock, OR it reaches 20 deg advance, whichever comes first, so if you give it an extra 6 degrees to go to sense knock you'll get more power
