This wouldn’t capture cycles from the motion of unsprung mass (i.e., up/down motion of wheels/tires, brakes, hub/knuckle, etc. mass) but it’s better than nothing. The edc control strategy is in the frequency domain so the data already exists.

Well not a 25k car these days but coming closer to 60k miles, during 13 years.
Yes there are interesting data referred to, if it only was possible to capture...
. As mentioned I haven't seen any EDC "live data" on the couple of tools I happen to have. Also what I can see of BMWs own diagnose intructions/possibilities indicates there aren't much data being possible to accesse? There is a tool mentioned in the end for measuring on the EDC module, assumingly when it is taken out. Other than that damper needs to come out and be put in test bench?
