What you need to know is what position the eccentric shaft is in when the car is off. Does valvtronic default to min lift when you turn the car off? Does the eccentric shaft run to max lift when the car turns off? Or, does teh eccentric shaft stay at whatever it was at when you shut the car off?
I am guessing the valvetronic motor puts the eccentric shaft to either min or max lift when you shut the car off... I guess this only because the motor runs when you start the car... why else would it be running if not to move back to idle valve lift settings?
If you unplug the valvetronic motor with the car off and you can't get it to turn over then you know the eccentric shaft is at min lift. If the car runs fine then they are probably at max lift (get a log). No damage can come of this except the risk of blowing something electrical if you attempt to disconnect valvetronic with the car running or something lol
