A different valve could be used, but electrical resistance of the solenoid would need to be high and EEC settings could need tweeking to suit characteristics of the new valve.
When you plug the lectron valve back in does the volts gauge drop again?
So i canīt just remove the valve and work with something just mechanical?
Yes it does drop again when i plug it back again. The weird thing is that iīve just disconected it from the turbo and actuator and not the battery or the electrical conector of the valve!
