Electronic variable vane control
Electronic variable vane control

I installed a vac gauge (taking the signal to the vac actuator) and boost gauge into my VW TDI to learn about the vane control.
I could see that there is very low, nearly no boost when cruising. The vac is somewhere in the middle range (maybe to avoid surge).
When pressing the pedal the vac immediately jumps to max. so that boost comes up easily. Remaining the pedal somewhere in the mid range (coming from slow cruising) I have the impression that the unit just allows as much boost as stored in the map, way away from max. boost to get the car where the pedal wants it to go, like limited acceleration.
I wonder if boost and pedal are enough and if the pedal signal is an analog signal as 0-10 V or just a switch near WOT or even.

So it's boost and pedal-position as input?
