boost leak test done last night and 2 leaks fixed. which leads to another question.. sorry if I should post this somewhere else, but tons of air was coming out of my BC because it was backed off too far.. I did BLT and screwed it in till leak stopped, but cant dial down my boost below 18ish..
 
So you will get ignored for being to cool to fill out the template that has been re-re-re-re-re-re-re-re mentioned an exhausting amount of times...

You have one log with a tiny interval of info.

So dont expect anyone truly knowledgeable to help, cuz Jesus helps those who help themselves.

But as a parting note. you shouldn't knock with suck rich ratio, low timing and low boost.....

So you have bad gas, bad sensor, or just ignore the count at that low rpm range.
Do a decent 3rd gear pull with 100% throttle.
And redo a thread if remotely interested in any real help.

P.s i tend to hit the "ignore thread" as most do when these threads come up...........

My apologies. Brand new to this site. I'll make sure I research what I need to do first before I ask any more questions.
 
So, In direct access, I adjusted the AFRatio in open loop to be much tighter between Min and Max, as well as a bit leaner. The numbers under heavy load were set too low. It was very rich at full boost. I also adjusted the VE table to match. It was set very high in the mid range 3000-5500. Some of the numbers I started with were as high as 108. The tune is by no means perfect, but at least the knock at full boost seems to be better.
