You don’t need any equipment! As I explained in my post, the values displayed as “percentage damping“ are NOT percentage damping but ARE solenoid voltage duty cycle. They are a direct window to the operation of the valves. Getting the numbers I need takes about one minute…. Go to the Suspension Info screen, set the ride to Comfort, step on the brake, and record the number for Left Front Compression. Set the ride to Sport and record it again. Then record it for Advanced, Ride Comfort Soft through Firm. You should have 7 numbers ie. 0,28,0,0,4,8,20 (these are my numbers). BTW I have previously proven that the valves are Normally Closed. Thanks!
