The PID constants will be unique to the system.
My P was 158,
with an I of 0.001

I was unsure of how high the values could go, so I tried something pretty high in my opinion (So used to numbers from -1 to 1 ). When it wasn't quite working, the next thing i jumped to was I control.

What is the range for the PID constants? 10bits + sign (-1024 to 1023)?
