After uploading the latest revision and reflashing the ECM, the car is running noticeably better. During normal driving I’ve observed some feedback knock and fine knock learn values ranging from about -1.00 to an occasional -3.00, though the DAM remains stable at 1.000. I’ve also noticed what appear to be false knock events during transmission engagement on downshifts before a WOT pull, with values around -10.00. However, there were no corresponding changes in DAM, fine knock learn, or feedback knock values. Boost now generally stays under 20 psi, but during a WOT pull it briefly reached 20.03 psi before cutting, whereas most of the time boost cut occurs around 19.5 psi. The P0244 has not returned, but the P0420 code did reappear during my drive this morning, which is understandable given the setup.
