Log and SAFC advice, log suggestions

[OldSchoolMotors]

Ran several logs today here are the first and last, as I was making adjustments to the SAFC-II. From the 1st to 4th log looks like I'm getting closer to tuning out the knock? Suggestions, advice, rants, etc... welcome.

I'm almost in the +% with the SAFC-II high setting that seems like a lot of fuel for 550cc on a 2g MAS and 14b? No?

Damn something got screwed up when posting, the numbers are all shifted to the left, hard to read that.

Try to get a .doc posted Monday morning.

It is a little hard to read but you have tuned out a good bit of knock. The first log shows a considerable amount of knock above 5k and your ignition timing suffers severely. On your last log knock is kept to a minimum and the timing curve is looks pretty good 9 10 11 12 13 15, then it drops off at 6k. A stock timing map shoud peak at about 15, 16 and stay there. The knock count goes up at 6k too so I would richen it up some there. I never tune by just a narrowband o2 sensor but if your o2 sensor is working properly then most people want to see between .92 and .95v at wot.

Sorry I was just trying to get a .doc setup, the copy and past didn't work that well from notepad.



Attached is log file :

Trying to figure out what happened between 6031RPM - 6281RPM - 6156RPM on second log?

Is that a miss-fire ? I have new plugs , but my plugs have some miles on them, one coil is chipped but boot covers sufficiently?
