Knock DTC and Funny KR Readings at part throttle.
Doing my Auto VE tune and keep getting this DTC,
P0327 Knock Sensor (KS) Circuit Low Frequency Bank 1 MPHC ($10) "Powertrain Control Module (PCM)"
I have also noticed that at around the 4000rpm range there is a shudder I am hoping it is just due to the afr at this point being commanded 12.5 but actual is 11.3. But going over my log at WOT and part throttle (enough to go into PE) i keep getting serious KR 8 degrees, timing is only set at 27 degrees @ 4000rpm 45 grams sec. I would have thought this to be very mild timing? using a 95 octane fuel.
here is the log

and the tune
