I drive a 2004 Forester XT 5 speed with 170k. Using an AP with an OTS map from Cobb (at least that’s what the previous owner said)

Just the other day my DAM dropped from 1 to .750, feedback knock and fine knock learning remain at 0.

Should I be worried?

OTS maps arent the greatest fit for these cars given all the variances that can be involved. They were developed under perfect conditions with the vehicles being tested in proper running order.

Try switching to a lower octane (or lower WGDC) OTS map and see if that helps your situation. ultimately, a proper protune is the best solution here, but switching to a less aggressive map is the next best solution to this. Example, if you are using a 93 map, use a 91 map, even if you are using 93 still. Leaves a good safety buffer.

Generally a DAM movement signifies a good amount of noise being detected and such that the ECU is globally removing timing to prevent further engine damage from occuring.
