Looks like you're knocking real bad up top. Richen it up some, and see what happens.

 

[cuong1106]

but what about the o2 values? it says that im still rich. anyone else have inputs, thoughts, or opinions?

 

[Violater101]

Yeah, it appears that you really start knocking around 6500. However, with that said, I would imagine that the car is actually pulling timing before that even though its still advancing. You need to do a pull at 100% TPS or WOT in 3rd gear from 3500 and up. My guess is the car is pulling timing for cooland and intake temps (that won't show up as knock, but it will reduce your timing by atleast 2). As for your 02 values, I don't like to rely on those....better to look at your timing curve and use them as secondary guidance.

my curve looks very similar but it's wierd because .95 seems plenty rich. I know you can't use the O2 values or rely on them, but if the car advances timing at .97 I don't see why it would pull it at .95. Try to richen it up from the 6k mark I guess and see what happens.
