After playing with Mp and APM2 looking for the CH6_opt for tuning as described in the wiki I started looking at the source.
I see the CH7_opt can be defined in the config file but no mention of the CH6 and the box does not seem to exist in the current MP

In the CLI you can go to setup and manually set the CH_6 option with the tune command.
You'll need to look up the values in the defines.h file, but it's pretty clear once you find it.
// CH_6 Tuning
// -----------
#define CH6_NONE 0
// Attitude
#define CH6_STABILIZE_KP 1
#define CH6_STABILIZE_KI 2
...
The CLI command range will lat you set the scale like this:
range 0 1500
This means 0 to 1.5
The mission planner hides the Interger funkiness from you, but the CLI does not.

radio_tuning
radio_tuning_high
radio_tuning_low
are the parameters assigned to CH_6 tuning.
They are stored as ints but converted to floats on the fly tuning() in Arducopter.pde
static void tuning(){
tuning_value = (float)g.rc_6.control_in / 1000.0;
g.rc_6.set_range(g.radio_tuning_low,g.radio_tuning_high);
switch(g.radio_tuning){
...
}
}
