Hello.
I have a profi tx that I use for a 1:12 scale wheel loader.
There is 3 hydraulic functions on the wheel oader, steering, boom up/down and bucket tilt.
Now I use a magic switch to activate the hydraulic pump as soon as I use the 3 function on the sticks. The magic switch then activates the pump, that works fine but the pump only run at a preset speed, I would like to have like 15% if one function is activated, 30% if two functions is activated and 45% if all 3 functions is activated at the same time.
How can I acheive this ?
