Daesun,

Although, I'm not too clear on the finer points of the Snow Chain function I believe you are correct in terms of the cutoff speed. Somewhere from ~25-40mph sounds about right.

I don't know if it's a partial disable of ASR or full cutoff and i'm not willing to find out in case it frieds the electronics :p

Does anyone else have a clearer understanding of how it works?
