very high knock

[overboostedtsi]

I did a 3rd gear pull tonight and my log looks horrible. My mods are in my profile.

RPM Knock Timing Throttle O2
2843 0 24 40 .82
2937 4 20 42 .82
3343 15 16 70 .90
3750 13 16 100 .92
4125 12 16 100 .92
4593 15 11 100 .94
5000 21 10 100 .92
5312 43 4 100 .88
5543 43 7 100 .86

Why am i knocking so much? I am only running 9 lbs of boost right now also. Any help would really be appreciated.

What are you intake temps. Also, .82, .84 and .86 might be a little on the lean side. If you have control over your timing I would pull back your timing as well.

intake temps were around 57 to 60 on the log, it was pretty cold outside. You mean set my base timing back?

idk about that being on the lean side, idk if my o2 sensor is dying, but i have my car running almost perfect right now, and see 2 counts of knock at 6k rpm w/ an o2 voltage of .84-.82, if i tune it to run "richer" meaning .89-.91, it hits fuel cut...so idk. What gas you usin?

92 octane

What's your IDC at? I don't see bigger injectors in your mod list.

Going off narrowband o2 voltage is worthless, gives you a vague idea about what is going on. ECU doesn't even acknowledge its existence at WOT anyway.

What plugs are you using? You better be saying NGK-BPR7ES
What are your high fuel trims? If they're at 140% I hope you're adding fuel on that AFC of yours
Whats your base timing set at?
