Default Another Data Log - 05 STI

I'm new to data logging and trying to understand what I am seeing. I have researched some about the topic but have a lot to learn and more research to do. It will take a little time to feel confident I know what I am looking at. Hoping some of you could help out.

2005 stage two. I did a 3rd gear pull form 2K to redline and went into fourth. First time logging so may need to clean that up a little. I think on this pull I hit the divider ribs in the road so there may be some "noise" in this log, not sure.

Do I have parameters required to determine if the tune is safe for my car? Also new at Google Docs so I might have issues, I will find out.

How does the data look to you all, thanks!

Nobody, wow.

Anyway I think I have a little better understanding about what I am looking at. My FKL looks good, all at zero in this pull, my FBK hits -2 at high load, high boost and at a high RPM in the pull. This is not good although I think this value being what is and with the other data as I understand it is not so bad.

I think I did have a knock event and the -2 going back to -1 then 0 in this pull is one knock event?

I'm not sure what other values in the log need to be looked at along with the FBK and FKL?

Got your PM... I've been out of town for the last three days.

Do your log again from 3rd gear, 2,000 RPM to redline. Then again with 4th gear. Make it two separate logs.

I will later today after work. Here is a link to another thread I started with three more pulls, 3rd gear from 2k to redline.

Thanks

Here are the new pulls, 3rd gear, 2K to redline and 4th gear, 2k to redline. Same stretch of road. I had more feedback knock on the 3rd gear pull than I have seen in any of my logs so far. I did two sets of each and the second 3rd gear pull looked about the same.

3rd gear pull

4th gear pull

Thanks

Default Re: Another Data Log - 05 STI

After graphing the logs out, I would be curious as to what your AFR is. What octane fuel are you running? Timing seems pretty high up top. Depending on your octane, it may just be too much timing at peak boost. Try reducing the global timing by 3 degree via the AP (under "Tune" and "Adjustments") and do another 4th gear run.
