my phase3 has never worked properly and would now like to work out whats wrong. The boost is only controlled by the actuator and there is no overboost. So it hits 1.5 bar and doesnt drop back to 1.15 bar, just holds 1.5.
I have measured the map sensor and rigged up a little test rig where i can apply 0-2 bar on the sensor and measured its resistance.
Anyone know what the resistance should be for a given pressure?
The amal valve clicks ok on the self test and the pipes and connections are ok. I have a new actuator and decent turbo and wastegate.
