How to map a 6-note scale to the white keys without any gaps

How do I map a 6 note scale across only the white keys from middle C = 256 hz without any gaps?

I tried to modify one that mapped 7 note scales only to the white keys, into this:

! Size of map:
10
! First MIDI note number to retune:
0
! Last MIDI note number to retune:
127
! Scale degree 0 is mapped to MIDI note:
60
! Reference MIDI note for which frequency is given:
60
! Frequency of the above MIDI note:
256
! Scale degree to consider as formal octave:
6
! Mapping:
0

But I had wildly unpredicted results, haha!
