Wastegate setup Sti hatch
Hi i fitted a turbosmart internal wastegate actuator to my sti 08 hatch. My question is does anyone know the procedure of how to set it up. My car is running at about 350bhp at 1.2 bar of boost. Some people have said it’s just a matter of fitting it at its weakest setting and running it, others have said it would need a tune/map adjustment!! I haven’t got a boost gauge fitted so don’t know for sure what will happen with the new wastegate! Thanks |
Do you know the spring pressure of the new actuator you have fitted? Typically I believe the standard STI has a 0.8bar spring in the standard actuator.
If your new actuator is uprated and stronger than this (which I suspect it is) then it will probably need to be mapped in. You can get a simple logger plugged into the ODB2 port on your car and run something like Torque Pro or BTSSM on an android device through a KKL cable with USB OTG adaptor to log the ECU boost pressure. |
are they not fixed based on the internal spring pressure, with only the preload adjustable on them?
just use TorqueApp to measure/log your boost profile before fitting the new turbosmart then fit it and log again and adjust where necessary |
I agree Gambit, when you fit them you only adjust for the pre-load so they are only just closing when static.

The spring in the new actuator is 7psi. |
