I'm now wondering whether many of your unfathomable problems with SCP are down to the way you've described using your fusion 101 supply. 

When I first started getting an Oxigen team together "Kessel Run" , I struggled getting the component  parts for home car (setup and testing) together. 

I found that powering the controller from the same DC supply  leads (that feeds the car)  caused all kinds of problems. More problems than I can list.

I bought the 201ADJT and all ofthe issues went away. 
I suspect that the 2 DC outputs for the 201 are separately regulated from the AC input so noise from the motor can't  impact the controller.
