You can probably find what you're looking for at HPTuners Tune Repository... If I had something, I'd help.

No there isn't, but here is a second gear only WOT run log, I think this is from when my car was completely stock, maybe had my rotofab on it I can't really remember.

Can you tell me what you are trying to figure out or looking for?

There are lots of tables that modify the timing tables. IAT, coolant, humidity, mixture, etc. You can switch your wideband to read A/F ratio instead of Lambda if it helps to better understand what your car is doing. Log fuel system status-that will tell you if you are in closed loop or open loop. If it's in closed loop, it's going to try to run 14.7:1 air/fuel which is 1.00 Lambda.

Here is 3rd gear pull in my 2018. There is some data before the pull where the car is just cruising in closed loop. You should be able to make a side by side comparison.

This pull shows .87-.91 Lambda in PE @ WOT, not 1.15? Timing looks about right, honestly could probably take more seeing as the car appears to be on E85.

Also I'd work more on your fueling for cruising as well. Cruising your bouncing from .98 - 1.05 Lambda. Also looks like you may have an exhaust leak on bank2 as you get random times were you spike STs by 27% +

The mixture at WOT goes from 13.2 at 2,000 RPM to 12.8 at 6,400 RPM. The part throttle is a little rough, but the LT trims are close to zero. I had the car retuned for the headers, but the retune was so bad that I had to revert back to a previous tune. The tuner added 86% to the MAF calibration and strangely enough I had a check engine light. I got my money back for the retune.
I have just tweaked the tune to get the trims close, the WOT air/fuel where I want it and the timing at WOT close to where I feel that it's safe. I am waiting on a tune from Pray-paid and sent him my stock file last week. I appreciate your input, but I don't want to thread jack the OP.

I'm dumb. I thought that log was for the OP

OP if you have a log you could post I'd be more than happy to look over it for you. If you need any remote tuning assistance just lmk.

EQ and lambda can get a little confusing sometimes if you haven't used all of them before:
