I Just got my cobb apv3 and uploaded a map for my car which has just a green filter and fswerks intercooler on it currently. I'm using 93 octane fuel. I've only done one redline pull so far because their aren't many safe sections of road to do a 3rd gear pull with the weather we've had lately. I was also going uphill a little bit during this pull in 3rd gear. I was a little concerned to see that one cylinder showed some knock, but I'm not sure what all the parameters I logged actually mean so I've made this thread to get some help analyzing the information. Here is the log:https://www.dropbox.com/s/ld04n1l78rlters/datalog2.csv?dl=0

I was told you should have the octane adjust ratio between -1 and 0 and if its going towards +1 then the map is too aggressive for the fuel. There are several points I logged that were titled octane adjust ratio but slightly different and one of the parameters starts going between 0 and 1 which is also slightly concerning.

Hi Ryan,
Sorry on any delay in someone responding! Usually its because people hate getting raw CSVs cause they're mamby pambys about using the CSV. A lot of people around here use and support Datazap. It's pretty sweet so for future logs you may want to use it so that you get a response sooner :)

Here's your flatland log:

Knock wise you look fine. It looks like you may have just flashed your map as your OAR is pretty close to zero.
You logged all 3 OAR logging monitors, and the one most people call OAR is "Oct Adj Ratio Lrn Mult".

The ones you have are:
Oct Adj List Stat Enum - A value of 1 indicates that the ECU is listening throughout this window to determine how to adjust OAR.
Oct Adj Lrn Axis Raw - This indicates a factor that will be used to lookup how much to add or subtract from your OAR once the listening window is over.
Oct Adj Ratio Lrn Mult - This is the normal "OAR" you have read about. It is used as a multiplier against several timing tables that are then added onto the base timing. In general, a positive value will subtract timing, a negative value will add timing. How this value is used can be configured by the tuner however, so its best to ask them how they intend its operation to be.

Some suggestions in the future:
Log ETC Angle Actual. This shows us the position of your electronic throttle control system. It looks like your boost kind of waves up and down when you spool up. This is probably due to a throttle closure.
Log WGDC Actual. This lets us see how your turbocharger wastegate is actuated. It is a primary facet in boost control
Log one of the Ign Timing Cyl monitors. This lets us see what ignition timing you are actually running.
