ECU Error after upgrade
 

I have just added a new turbo and intake pipe to my MY06 STI, when doing the fitting the Tumble Generator Valve Actuator cover was removed by mistake and now I am getting an ecu error when the car is started. The error being "Tumble valve closed".

Does anyone know how to adjust the tumble valve actuator or is there something else???

The car is due for a remap on Thursday desperate for the info.
