Re: vEx PWM Motor Response

In some of our testing, we did notice that the Vex PWM does follow a graph similar to yours (so don't worry, you're not crazy). As far as trying to make a linear relationship, I would suggest trying to just not allow the controller send values to the motor if it falls within the deadband near 127 or at the nearly flat part of the curve near 220 and 15. If you want it even more accurate, you could take just the values described above and find a best fit line which you could then plug into your program.
