Ok... I've been logging when I drive to work and I've seen knock in the 2500-3000 under the 70-90kpa load range. The knock is about 2-5. I'm one of the lucky ones that get to run 91oct gas. ": (

I've pulled a degree of timing from these cells and the surrounding cells to try to reduce/eliminate this.

Anyone else seeing this???

Sure you don't have a valve problem? I had a similar problem before only at a certain RPM and it turned out to be a hole in the #4 exhaust valve (too hot), was a Starion Motor though

 

i would pull out another degree, especially in the neighboring cells before the knock.
i'm glad we have 93/4 over here on the right coast

 

LOL true that

almost makes me want to stay on the east coast when i graduate, almost....

 

I see a similar thing at partial throttle around those loads but at WOT its fine so I quit worrying about it. Try logging a couple of WOT pulls from 2.5 - Redline, that will paint a much better picture of what needs to be tweaked. BTW, I am running 92oct on a stock 9.

 

I see this a lot as well. One of the popular guys in ECU forums (JohnBradley, NJ, EVO-Kid, ect) posted that this is pretty common. I know I dont usually hit over 3 knocksum so I am not incredibly worried about. MY car isnt really tuned though.

 

ya just keep taking out 1 at a time until it disapears. Or just decrease your open loop low load throttle map so you go into open loop at part throttle.
I would try decreasing timing first.
