The ejection burn from Kerbal for transfers to Mun and Minimums is wrong for patch 0.2.0 and the spacecraft never reaches the SoI of the other body.

For exemple, with soi_adjust = 1 :


Planning Transfer: Kerbin -> Minmus
  current/target phase angle: 259 / 115
  Angles. rate of change: 0.17364 delta 144.1 -> time 13:49
  body info : radius 600000 SOI 2247428.3879023
  transfer to alt: 44,152,572 m  in 13:49
  eject at phase angle 114.9  ejection angle -1.0  dV: 889.51 m/s
Maneuver: dt: 13:49  dV: 889.5 m/s stages: 0 burn: 0 s  burn: 0 s
    stages:

If we go to 1.5 :

  transfer to alt: 66,228,857 m  in 15:37
  eject at phase angle 114.9  ejection angle -1.0  dV: 896.14 m/s
Maneuver: dt: 15:37  dV: 896.1 m/s stages: 0 burn: 0 s  burn: 0 s
    stages:
  done.
Vacuum burn dv: 896 m/s  dt: 54 s

So the transfert to alt seems to be increase, but the ejection angle is not. I never end in the SOI of minmus.

Hope this is helpful ...

Yes it is. I'll debug and try to do so this week.
