generally if your getting knock leaning it out will make it worse on petrol. suggest you pull a bit of timing at the rpm\load area from the base-timing-B table pull a bit over half the knock correction you see and a bit from adjacent cells see knock correction thread below
For some reason the knock only seems to happen at cruise. I've only seen it 1500 - 3500 RPM. Same behavior on 93 and E85. I'm already running a bit rich in places, so don't think I'd want to run richer. I've got 2 sources available for E85 so I need to try the other to see if it's any better. If it's not, I'd be up for learning how to edit a few tables. It's only mild, transient knock, but still.....I'd rather eliminate it. Thanks for pointing out the knock correction thread. I'll definitely be checking that out.
