my o2 readings pk or real knock?

[larrys91talon]

i live in phoenix and as you no its 110 degrees out,anyway im showing up to 30 counts of knock on my m130 with mmcd from 5k to 7k,1k to 5k i get 0 counts.my o2 readings from 1k to 4.5k are .89 at wot and 5k to 7k .85

im running 17psi on 14b with stock side mount,550cc,2g maf,3in. exh,intake,walbro 255,afpr,mbc,apexi neo.

my o2 readings look good to me for a 91 talon tsi with 160 compression so im thinking its phantom knock.what you guys think?please help im bout to just relocate the knock sensor.

max ijdc is only at 68% tps 99.6% but fuel trims: low 81% mid 85% high 100%

any help much appreciated.thanks

What are your o2 readings at WOT in 3rd. You should be around .92 volts to keep a safe A/F guesstimate.

sorry, that is a 3rd gear pull .89 o2 from 1 to 5k then .85 from 5 to 7k.

i thought 2gs like to run in the .9x o2 readings but 1gs like .8x?vfaqs has a write up stating that,but correct me if im wrong.i dont get for one me having to go +30 on afc with 2g maf and 550s.

max ijdc is only at 68% tps 99.6% but fuel trims: low 81% mid 85% high 100%, these readings are low rich,mid rich,high normal,no boost leaks eather.
