FWIW, controllers don't push current, the motor "pulls" it. If htere is not enough of a load, then the controller current will not increase beyond what is required to overcome the load.
Using the dyno you can increase the loading on the motor to force current requirements up as high as the dyno supports, and tune the controller for best response under the highest loads you expect to see in real world use.
FWIW, you don't really need much current at only 11-30kmh, except during acceleration if you are trying to accelerate very quickly to higher speeds (quicker accleration takes more power), or climbing a hill (steeper takes more power).
