Turbo Soon
Here's what I see (and please someone jump in with comments or if what I am saying is wrong). When you went from a cruising throttle to full throttle your ECU was playing catchup while transitioning from closed loop to open loop. Our ECUs weren't really meant to adjust to load amounts coming on that quick. The knock sum is just that, its a sum. That's why it is decreasing as your RPMs are going up because it only saw a knock count of about 10-14 right when you went full throttle at 3125rpm. The real knock you should be concerned about is at 5625rpm and 5875rpm because your timing is too far advanced. My suggestion is to lower your timing in the higher RPMs and pull enough fuel out from 3000rpm - 6000rpm at 90%+ load to get your AFRs up to 11:1 - 11.5:1.
I just wouldn't do the same if I was in your situation, it's just asking for trouble. Realistically the motor isn't going to last that long anyways, you can't take an NA motor, slap on a turbo and expect it to be reliable for a long period of time.
The only reason you got a knock of 10-12 was from the changeover from closed loop to open loop and your ECU not being able to respond quick enough. It has nothing to do with the amount of boost you have. I guarantee you will see that knock again occasionally when you gun it. And sometimes you won't. It depends on how quick the ECU responds. The real knock you need to concern yourself with is up above 5000rpm that comes about after a knock count of 0.
it didnt make sence to any of us around here either other then the fact that it was waywaywayway to rich, but in the end that doesnt make sence either cuz thatd reduce knock. sence i leaned it out and knock went down, thats the only thing we really have to go on cuz thats all we did to get less knock

id like to see how much knock a rrm kit has with the piggyback. im just wondering
It doesn't make any sense though which suggests to me that something else is going on. If you have a 5 gallon drum of water and you put in 5 gallons of water but it's not full, what does that suggest to you? There's a hole in the drum, it's not actually a 5 gallon drum, you didn't have 5 gallons of water, evaporation, etc.. The same logic applies here (that is if something unexpected happens, there should be a rational explanation for it).

Because you will be knocking like crazy with your timing as advanced as it is up top. Knock is not just from not enough fuel. It comes from too much timing advance also. You can have it running rich and still have knock with too much timing.
yeah i hear yah. thats why we took away timing up high on the first upload to the car and it really smoothed it out, but as you can see from the first log i posted on here that i still had a lot of knock
just seems like a safer option until you figure out the problem. Shoving more air into an engine that is apparently having issues doesn't seem like the best solution to me.
