Okay, so how can I determine how much current a motor is drawing? Is it a direct correlation to a PWM value, or does it rely on other things as well?
Also, when you say shift points should be determined by trial and error,
what 'trial' should I use? How will I know?
I am also still wondering about "software synchronization" and lowering motor speed after up-shifting... (see first post)
Sorry for all the questions,
