This is probably the best explanation so far and upon visual inspection this is indeed what does occur (on my setup the motor movement is tuned out but still connected). SW calls it valve grounding.
But to Perdieu's point, this may have not been the case when this setup initially came out.
So we have 2 options:
1) Use the AFM module from EFI that is proven to work with no issues. This requires removal of the valve motors.
2) Keep the motors, but connect them to a grounded housing that has no physical moving flap but can still allow the motor to move (call this option whatever you like)
