Hey guys, I'm new to OpenECU but familliar with other tuning software/standalones

I bought an XPT Stage 2 map just as a starting point. My tuning was running great this summer, 18 psi on 3 first gears, 19 psi on gears 4 to 6.
A-F ratio of 11.8-11.9 all the way up to the rev limiter.

Now that the winter has arrived, My AFR meter started to show some leaning more and more days after days since the weather temperature is going down.

Today, if I floor my car, I see the AFR meter going up to 12.4-12.5, even 12.8 on 4-5th gear

I tried to change the AFR Target ratio table. nothing.

I am wondering if a subaru is always running on open loop, since I can't find a closed loop table for fueling. am I blind?

is there an enrichment table regarding the weather outside? since it was running fine when it was 90f outside. is it the barometric sensor?

Thanks in advance!
