    OK, thanks...was crazy on that last tune that i was getting so much KR just cruising along 70-80 range

    How can you tell that it is getting PE now vs before since so much KR still happening?

    Your commanded EQ ratio changed from 1.0 to .87. It's in your log. Would you like a screenshot?

    OK, thanks...i didn't know where to look for that. I assume before it was staying at 1. If it is in fact changing now, any guesses to why i am still getting the KR? Does it need to command lower than that .87?

    Sweet, been waiting for people to post videos of it as I look at them each year. Wish they did the cruise when I lived up there.

    Could TQ Management Drivers Demand Tables A-C cause this knock? This mornings log just cruising shows a lot of KR. I have upped these tables quite a bit from stock cause I love how the pedal feels, but wonder if it could be my issue. As seen in the log it is mostly at speeds of 70+

    I took a quick look at "new log.hpl" and your getting KR above 70 kpa. Try enabling PE at 65 KPA if you can. Cant look at tune file right this second.

    Forgot to mention that I tried for my way home today lowering the tq management drivers demand to what my buddy uses and it did not help at all.

    I just took a longer look at your log. Steady state cruise and KR? What all is done to this car?

    The fact that it doesn't show KR all the time at those speeds makes it harder for me to know what i need to do. I thought about pulling timing at the g/cyl and rpm range of the issue, but if i don't get KR all the time in that range i am not sure it is the answer. What about Injector duty cycle? How do i know if it is hitting its limits resulting in the KR?
