You can choose between controllers that are programmable or non programmable.
You pay more for a programmable controller and 90% of all users never reprogram their controllers. They come set to 100% output with reasonable throttle and voltage parameters.
Typically I can get you a higher amperage control without programming for the same money as a smaller controller with program options.
One scenario where you may want program options would be if you were buying a really big controller now with plans for a big motor in the future... you would want to turn down the output for the stock motor now.
The guys at FSIP have a nice series control with adjustable (mechanical) throttle response and output.
Both Controls are compatible with the PQ motors. And both suppliers can outfit your purchase with a field map (program) to fit any major motor producer on today's market ~ all you have to do is ask
