M84 SR20DET

[Vlad]

I was thinking of making an external boost adjustment, via a on/off switch or a fixed 5 position potentiometer. Since the M84 dosen't let me modify the source of the axes from the tables, the one i can use is 'comp2', witch reads 'user input2'. I am thinking of calibrating 'user input 2' on 1-1 voltage, and put the sensor voltage as the axis in the 'comp 2' table, with the coresponding % i want to it.
And, if i just make a on-off switch (low boost-high boost), dose this input calibrated as i mentioned up, have a pull up resistor? Do i have to switch it to ground or to 5v.
Thanks, Vlad.
