What could make it read that high? It seems skewed on the high side from my gauge reading. My digital gauge came in I just haven't had time to install it yet. This was a freeze frame from the O2 fault. It may be failing, or its going lean/rich for a long time I guess? It's been almost 10 years since I've messed with supercharged computer controlled cars and haven't had an O2 fail in probably longer than that. If I remember right the output is from 0-1V with Stoic being about .6 or so and lean being almost 1V?

edit: holy crap I forgot I filled up with 87 octane last time, no wonder it's knocking. I'm down to about 1-8 so I'll run it dry on the way to work tomorrow and fill up with premium.
