Default Impreza STI V2 turbo problem

Hello scooby Fans !

I've got a problem with my Impreza STI V2 1996. About a week ago i saw CEL number 44 (turbo wastegate malfunction problem). Since then, my scooby cut-off fuel/boost over 0.6 bar Do you have any suggestions what may causes this problem ? I would add that I've got 3-port boost solenoid that has been cleaned and also replaced with another one and the problem is still present. Thank you all for your help and best regards, Matthew.

Could it actually be the MAP sensor showing a false pressure at the ECU?

Oh, and did you reset the ECU after cleaning your 3 port?

I cleaned and checked all plugs and wires in solenoid, turbo and MAP sensor yesterday. Moreover I cleaned Air Flow Sensor and my mechanic checked timing belt and it is in good position. I haven't replaced my MAP sensor yet but today I ordered another one and I'll change it tommorow. After cleaning all of this parts I disconnected the battery for hole night and the problem is still present, check engine light too ...

After a long search we found that the ECU is fault. Does anyone have a 6K ECU (impreza sti v2 my96) for sale ? Thanks for your interest.
