Hi guys, I got my fuel tables pretty much sorted by now (city driving with a fully warmed up engine only in this log):

Looks good to my untrained eye.

But when cold, the engine feels powerless and weak. With my WB o2 sensor back under the car I quickly discovered the issue. Before the engine gets warm enough to enter closed look (CTS reading of 58°C or something like that), she runs unbelievably lean with 16-ish AFR readings.

What can I do about this? There must be a more elegant way than setting the fuel tables pig rich and let closed loop sort it out....
