I've had this car since last year. 2018 STi limited. I have purchased it from previous owner with only 5000 miles. At this moment, it's at 22K miles. 2 weeks ago, DAM, Feedback Knock, and Fine knock learning started acting crazy. Especially when I have 13-15% throttle holding on the pedal within 2k to 4k rpm, FKL gone to -11 and few seconds later DAM jump from 1 to 0. And then, it never got back up to 1 again. After that, DAM stayed at 0 at all time. And whenever i do 13-15% throttle within the same range, FKL does the same thing. Also, before it enter the 2k range, the car seems to accelerate fine. Then when it hits the range, as soon as the FKL gone -11, it feels like loss of acceleration for a moment, and slowly picking back up. It's weird. (Time for a new block already?? Lmao)
I thought it was dirty intake filter since it hadn't been cleaned so I cleaned them properly following the instructions from Cobb. (I got the SF package) oh well. That didn't do anything.
When DAM got to 0, no matter if it's in I, S or S#, the boost didn't get higher than 12. Usually, it's 18-19 psi range.
Please help me🙏 I don't wanna a new block yet. It is too young for this. Thanks
