Please look at my log "knock"

Have you had the caps replaced on the ECU?

I am trying really hard to be nice man, but you are killing me. Trying to determine an approximate a/f ratio from the voltage output of a narrowband (stock) O2 sensor is pointless. You need to forget about the O2 volts for now. Candiantsi stated in his second post that you are running lean and you need to tune for 0 knock. I stated the same thing since you didn't seem to want to listen to him. Seriously do not log O2 volts. For tuning wot you should be logging rpm, timing, knock. Richen it up to the point that you know it is a little too rich. Do a run and if you have 0 knock then lean it out a little and do another run. Keep leaning it out in very small increments until you see the slightest amount of knock. Then richen it up a little in the areas where it knocks, so you have 0 knock. This is all assuming that your car is in perfect condition before you proceed with any tuning. Some other members and I have pointed out things that may be wrong with your car and you should address those issues before you continue to do any tuning.

I don't know how well you can tune with just the maft but from what I have heard you should probably get an SAFC and maybe a wideband since you seem so interested in O2 sensors
