thanks for your quick reply weebertrix,

I'm a little bit confused now
So there are no standard parameters for the BW5 profiles, for example 'subfordata=0' I thought that reading the subchannels for data is disabled. In this case you can't compare it with '0 = *New* FAST topology (NO speed control)' it's not disableing something it sets another speed. I hope I described my problem that you got my point. If not ask me
