Here is a 3rd gear log that I did in Evoscan yesturday (20psi). pull starts at 14 sec. Other than small fuel adjustments, everything else is stock. Any suggestions?

Done. the zip now contains the CSV

The attached log is pretty useless, honestly.

You've got to at least log KnockSum. You should also try and log TPS, Fuel Trims, Wideband (if you have one) and ideally boost (if you can).

 

I figured as much. I"ll post another one tonight.

 

exacly what i was thinking when i opened it wheres the tps knocksum ect

 

What values am i looknig for in knock sum? how much is too much?

 

No one knows what knock counts hurt the engine but I think knock counts of 3 or 4 and above will decrease timing and hurt performance.

For me I'd try to tune to knock-free or random knock counts of 1 or 2.

One thing you can see from your log, I believe, is that your boost spikes to 20 and then drops a lot. What method are you using to control boost? You should setup your boost first as changing boost changes AFR.

 

I tend to aim for 0 knock, but that's not really possible if you want to make good power. I accept a few 1 counts and the occasional 2 if I have to. When it comes down to it, if you aren't on the verge of a small bit of knock, you are leaving power on the table.
