MC timing maps, anybody know?

Yes, you are right I suppose, what I really want to know is what is the 
standard timing advance for RPM and the standard retard for boost before the 
knock sensor is activated.  Maybe there is no straight answer if the control 
unit is constantly fiddling with it.  

When you program an ignition system, there are basic values that the ECU 
uses, before they are modified by temp, TPS, and other inputs.  I am trying 
to establish a baseline ignition map.

 Per se, there's no such thing.  There are two base maps to cater for two 
basic sets of knock characteristics - each map is two-dimensional (rpm and 
boost) and subsequently modified before use by inlet air temperature.
 Even at idle, the timing is not constant.
