Turn all the learning functions off, run the car with the controller turned [OFF] and establish what boost it will make on the actuator.
Then turn it onto [A] and work your way up. Set the target boost to, say, 1.00kg/cm and the duty to 30, then adjust the duty until you get around 1.00kg/cm.
See how you go with that.
cheeRS Christian,
I actually did that this afternoon and found with it off it only boosts to less than 1 bar. With the unit off should it react the same as if it had never been fitted. BTW a new actuator was fitted at the same time as the AVC. Now its using the AVC boost solenoid how should I set the actuator? Should I set the preload so it boosts to about 15-19 psi with the AVC off?
