yeah you are having some issues. your Ignition Advance Multiplier (IAM) has dropped to 13, meaning you are only using 13/16 or 81% of your whole dynamic advance map.

it appears that you have a flat dynamic advance map that is set at 10*. now since your IAM is 13 you are only gonna use 8*. im guessing it got rounded down to 7.5 in the ecu since those are the highest knock correction value in your log. so you are basically knocking over the whole rpm range except at 3300-4000rpm. since you already have a flat advance map i would just go in and make your advance map correspond to the knock correction values you logged.

you can go read some suggestions on how to tune this in this thread
http://forums.nasioc.com/forums/show....php?t=1432656

i am guessing your maf table wasnt rescaled properly for your intake and your af corrections are off when you go open loop. you are knocking the whole way from 4200rpm to redline.
are you running worse gas now than when you got tuned?

also, you should consider lowering your boost at the higher rpm since your injector duty cycle is going over 100%.

yeah, it was not feeling as good going above that 4k mark to redline. i think i need to get a new map on there and see how my car likes it. i could be fussing around messing with this one for a while and not make any progress due to my low understanding of tuning (and not trying to blow up my engine)

did u upload ur new logger defs? dl it first. unzip it. and go to "my computer", program files, enginuity...and once u open that up, u will see an existing logger file named 'logger def xlm" something along those lines. Drag the new file u just unzippped into the enginuity main file. It will ask u "do you want to replace existing file?" click yes to all.

You update the ecu defs the same way. I hope this helps. I was lost for a sec as well. As for ur being high, I would lose the short ram(if ur maf wasnt rescaled from your tuner), check ur throttle cable to make sure its not too loose, and most importantly, get ur IAM back up to 16. But I agree with above, if ur seeing 7.5* kc with ur iam at 13, I wonder how advanced ur timing is with ur iam at 16. But without the map, its still hard to tell. If u want u can pm me the map and ill take a look at it.

But start from there. My bro's car was knocking with his cai. Dropped his iam down to 0. We put the stock intake with a kn panel back in. Reflashed the same map and drove around until the iam jumped back to 16. You will be able to tell the difference when ur ecu is "happy".

logs things like:
load(direct)
eng speed(rpm)
idc
throttle angle
feedback knock
fine learning knock
knock correction
timing advance
maf flow
wgdc
relative manifold pressure(corrected)

note* some of these you will see once u dl the new logger defs.
hope this helps buddy.
