Hello
Can anyone look at this log and tell me if these numbers are within safe limits until I get a tune done?

Thanks in advance

Your numbers do not look like it will cause damage in closed loop fueling, you are never maxing out your AF correction and your af learning is not way out. Without a wide band it is impossible to fully evaluate your open loop fueling. You pulled about 7PSI at one point and your dynamic advance dipped to -4 (potentially an indicator of an issue). I would suggest staying out of boost until you have a full tune. what did you do to your car to need a tune?

Something is definitely occuring that the car is not happy with, whether it be a real feedback noise (actual knock) or in the more rare case, false knock at certain RPMs created from alternate sources such as a bad motor mount, loose bracket or even a dropped bolt in / around the knock sensor location that sets it off constantly.

Judging by the numbers im seeing, this car is in need of a proper lookover and tune from a reputable shop that knows Subaru's well.

Hi Mike

I figured it out, it was the exhaust baffle that goes between the headers was loose, it seemed to resonate at a certain rpm. I took care of the issue and DAM staying at 1.0, no more false knock!:laugh:
