Knock all over the place in that log. And even during wot runs. Try flashing the 91 octane map and see if the knock can be reproduced on a less aggressive tune with 93 octane fuel...

Log your knock sum and see if it is actually occurring when you see it in the fine knock learn. Take your oil cap off with the car at idle hot and see if smoke is coming out of it. Also check to make sure your knock sensor is not loose.

Well last night I reset the ECU and reflashed the same stage1 93 octane map. This time no knock, does it take the ECM time to adjust after a reflash to look for certain issiues? Here is a partial third gear pull after reflash.

I Will try this as well. I did dump a few gallons of gas in it after work from a station I have never used. Could bad gas cause this?

DO NOT LOG KNOCK SUM. Extremely poor indicator of an issue. The knock sensor being loose is another extremely long shot...

The motor has never been touched, Don't think the sensor is loose.

Here is a lengthy log from this morning after reflash last night. Seems to be quite a few events here as well. Also I seem to be noticing some overboosting but it was about 45 degrees out this morning.

Line 343 shows 16.78 psi!

Redo your WOT run from around 2500 to near redline if you can do so safely. Also try to start the log before you mash the throttle for the run.

Once the DAM reaches one, the only thing left for the ECU to make adjustments are fuel trims, and pulling timing if it sees knock.

Yes bad gas can cause issues. Thus why I told you to try out the 91 map with 93 octane fuel...

There is just too much junk in that log. It makes is a PITA to try to decipher what's going on during the run because you keep lifting out of the pull.

That log looked MUCH better. No knock. Try another run later today and post it up. Also I forgot to ask what car is this on, so I can go look at the map notes on COBB's website

Well I went to look at the map notes, and my phones stupid, and won't let me see them. But anyway, what I can recall from memory is the target boost level is 15.2 psi +/-.7 and boost cut is 17.xx psi at sea level.

The boost control system looks good. That spike is nothing to worry about, I have the same theing in some of my logs. I will have to take another look at the A/F tables and see if I see any extreme corrections, that might indicate a problem. Can you do me a favor and log the A/f tables on the next log you take, I only see the one?

This is taken from the notes on the Cobb site.

Boost Targets: ~13.5psi +/- 0.7psi peak boost pressure tapering down
to ~9psi, depending on vehicle and conditions. If your vehicle is
not achieving or exceeding the boost targets, you may need to
mechanically adjust your boost control system, please refer to this
document “How Subaru’s Factory Boost Control System Works v1.X” for
instructions.

I am not sure if I should be worried about that spike or not on line 9 on the last log or not, 16psi seemed pretty high. It was fairly cold out this morning and I did do a reflash last night. I heard it takes a little time for everything to get settled.

are you sure you are looking at the right map notes? I have an 06 WRX limited and those notes look like stage 1... Target boost for stage 2 for 06-07's should be 15.2 +/- .7 psi. I wouldn't worry about the spike... I have the same spike in my logs and Bill from COBB confirmed there shouldn't he any issues with that small spike. Its when it never stops building boost, and goes over the boost cut limit or over boosts and stays up there when you should he concerned.
