How is this engine even running??
So I finally got my idle issues sorted out (I think, I mean it idles ok) but after making a short run down the street (3- mi.) my fuel map looks..wrong. AFR was reading super high until veal started sorting things out. What could I have f-ed up so badly that I ended up here?
* engine is more or less stock, no turbo, stock injectors.
- why does auto tune seem to stop making ajdustments @ 5k?
req. fuel is 11.4.CurrentTune.msq

Where did your base map come from? Id say it would be worth while to find a good base starting map. I started with the one right from DIY auto tune then did Autotune and manual adjustments from there.
Autotune has parameters under the Advanced tab which prevent it from changing the map too drastically or potentially limiting tuning around certain RPM or KPa. Also note how your Tach in the dash relates to auto tune. After reading a lot I've found that the stock tach could be quite off. I don't hit my 7k limiter till about 8.2k on the stock tach. This could explain why it "stops" at 5.5k

It started as a base map from diy but I changed a lot on the maps. For instance, the base map lists the kpa range to 230. I am NA so I changed it to 105. I'm not too concerned with the tach. It seems to be fine. What I am concerned with is the 250 + fuel numbers.

I don't think there is a way to without it being plugged into the car but someone else may be able to prove me wrong on that that has more experience.
But I think i found the cause. You warm up enrichment starts at 100% then goes down to 20% once its warmed up. This means its actually cutting 80% of the fuel when its warmed up causing your auto tune to have to pile in the fuel to make up for it. Mine is like a gradual slope down from 170% at -40deg to 100% at 180deg

Brain, in one of my other posts regarding the 02 you said that I could be getting an incorrect signal because I was using the factory signal wire in the loom, but you thought I was running the narrow band at the same time. I'm only running the wide band through this wire but is that still incorrect to do?
