Part Throttle KR

Is part-throttle KR something I should be concerned with? In higher gears (mostly 5th and 6th) if I roll into the throttle I get about 5 degress of KR or so. However, if I just poke the throttle and make sure I achieve PE I dont see any KR. What is your guys' feeling on this?

I really appreciate your input on this! Thanks in advance.

This is just showing you that the speed density
side of the tune is not really right, or that you
have too much advance for a non-enriched
mid-MAP operating point. I'd more suspect the
former, look for an O2 voltage dip preceding
the knock detects to decide.

Speed density = VE, correct? Thanks for the info, I will have my tuner take a look.

are you talking about low rpm, high map, high gear moments when you get knock?

then it's normal, you're creating a huge load on the engine and knock is a reaction of that. you're stressing the engine past it's natural limits. if you need to accelerate, downshift
