im suprised theres not a dual gang potientiometer wired to a thumb/twist/knob that will do this without this and that piece of awesome technologies inbetween... would that not be a simple thing? maybe i should try and 3d print something like that, as soon as i figure out the resistance of the throttle i got a box full of pots for building big muff pi's and overdrive 250's, I dont imagine it would be difficult but there would be no easy way to fine tune the performance together stand alone.... or i might eat my words and feel like a dummy...
