Prelude: I have an automatic and I have no idea how to run a log on my car w/o doing the upshift mod and locking in my gear. (If you know how to get a decent log out of an auto please let me know)

This log is me putting it in 2nd, WOTing it from a stop and it going from 1st -> 2nd, bouncing off limiter and into third.

Bolt-Ons: MAF-T Blowthrough setup, Greddy Type-S, K&N Filter
Fuel Mods: SAFC2, MAF-T v2.01

I just installed the MAF-T and instead of setting my injectors on it and tuning it on the SAFC-2 (easier) I wanted to tune it on the MAF-T box so when I get a 16g all of my 16g tuning will be on the SAFC2 (sorta making the MAF-T as stock as possible, like it should be)

Okay, I understand it's a really hard to read log and it may make your suggestions inaccurate, if you guys have any ideas to help me run a better log that would be great. Thank you. BTW My alternator stranded me yesterday so I gotta install one of those tomorrow so I have time to tune =)
 
although this is purely based on a narrowband o2 reading, you should ideally tune for around .92V at WOT. If you look at the second gear pull in the series, you will notice that your o2's are running too lean for a 2g. I would begin by adding 3% from 4k to 7k. Then logging and retuning from there. by 7k RPMs you ideally want 18-20* of timing. I'm sure if you went a little longer on the WOT (assuming your auto won't shift) you would get 18*. The whole trick to tuning a 2g is to get a smooth graduating timing curve. You can already see the dips (knock) in the curve and the flat spot at 6k rpms.
