My second attempt on a Datalog.

[ARES28]

Updated ATR and rid some unneeded parameters. Hoping this log is more legible. I do not like the knock up high though. Thanks for looking. datalog7.csv

No one?

log looks good, seems like you should be pushing more air, and by that i mean your maf hits like 221 and tops out...but maybe thats your altitude... it could be that you need to pull a little timing at that spot...it hits 9 degrees and knocks and drops back to 8 and starts climbing again. could be the plugs or crappy gas, bats look good fuel pressure looks good and you seem to be hitting 11.8 which i assume is what you are targeting...all in all seems alright maybe just a revision on timing.

could have been something banging in the engine compartment...i believe @phate would suggest a few gallons of e85 in the tank to see if that takes care of the knock, if it goes away its really knock if its still there then it is engine compartment crap banging around...my engine noise was around 3 to 3.5 and was due to the intercooler shroud tapping, which i fixed by putting some rubber between the intercooler and the shroud.

just a few things to look at.

Right on! I am targeting 11.9, but only have 70 miles on the tune......I was thinking the same about dropping timing up high to lower that knock. Thanks man for the reply......

I was thinking it was engine noise too......just don't like how it reads 2's and consistently drops....I will try the intercooler to shroud padding though. Thats a good suggestion.....

<225g/s and <4.2V??? I can piss out more air out of my peepee. Like stated throw some eth in the tank to see if it gets rid of knock.

Get more flow mods.

I think this damn altitude plays a roll......you are correct though, i need a DP..........

Aw I see colorado...elevation ftl.

The dropping is the scaling on your kr settings, you can decrease the time it takes for it to climb down by adjusting a value in atr. It's in bucker's guide, decay rate to 150, that way it's easier to identify where the event actually occurs. Also make sure you change max detection up to redline aka 6700.

I have my decay rate tables, A and B set to 140....I do need to jump my Knock retard Active RPM max from my 5750 to your 6700 though, per your suggestion...........Thanks again for the help ScarMS3, i do appreciate it!
