megasquirt and knock sensing

I have recently finished and managed to start my project RB25det build which idles fine at the moment (thank you HPA).

I'm running the standard Nissan RB25det knock sensors with a Megasquirt pro evo

only problem is I'm not sure if I have the correct settings for the knock sensors or if i have the knock window setup correctly because on idle it is showing knock where there isn't any I presume.

is anyone using the standard knock sensors with a MS3 who wouldn't mind sharing what knock settings they have for me to have a good starting point?
