3sge (3rd gen) Octane? Options

[czwalga]

3rd gen 3sge does anyone know the recommended octane? Or most likely RON since it's not a US engine? I've been bashing my brains in trying to figure out this problem and refuse to go to another race with it. After about 30 hard miles 5k RPM.... the engine starts cutting out lower and lower in the RPM range until I cant rev over 4k RPMS.

I've been running 87 octane, i'm thinking the knock sensor could be detecting something and slowly pulling timing.




If this is the case i'm an idiot, and created a lot of headache for a stupid easy fix.... just sucks cause there's no easy way to test it.

Have you tried 93? I know the 3rd gen 3sgte will only run on 93 pump do to the higher octane levels in Japan. My 3sgte will start to knock with anything less. Maybe your 3sge will benefit by running 93 pump gas.
