How a electronically controlled Steering Damper Works (2017 GSXR-1000)

Land Bowyer was kind enough to send me a 2017 GSXR-1000 Stock Steering Damper to test out on my new 2017 GSXR1000 Bench that I've been tinkering with.
I was curious how the control worked for the stock damper.

When active, it has a frequency input right at 1.0 kHz, and varies the duty cycle up to a maximum of 66% at 200 MPH.

It doesn't go active until about 40 mph.
This is what I saw on the bench. I am not sure if anyone has used a MaxxECU to control one yet or not.

Hi. This is a little different. Have used a MAXX PDM 20? I just ordered one front Eric at DAS.
