Default NB iac hum

I'm trying to silency my humming iac, but ms2extra won't let me use a frequency higher than 30.5*8 = 244Hz, where the stock ecu runs it @ 500Hz.

Is this 244Hz limit a hardware or a software thing, iow, why can't we enter a number higher than 8 and would it be possible to change this in the code?

On a sidenote, what do you guys use for cranking duty (%) ?
