boost pressure control?

[firetire@hotmail.com]

Hello,

I am not clear about the engine management in the legacy turbo 2.0,
the ecu can control the boost pressure? or is only the force at the
waste gate actuator, what is the purpose of the solenoid between the
waste gate and the manifold, why is not directly connected. I think
that the solenoid is actuated by the ecu to open the wastegate when
the map get a desired boost reading, programed at the ecu. Please
tell me if I am wrong. I am asking this because some chips
manufacturers claims that they can increase the boost pressure.

Thanks,

Christian

Christian,
the ecu does control the boost setting. An aftermarket chip can change boost settings. My chip runs a boost of 15-16psi and also has the fuel cutout at 19psi. If you are interested in this chip, he does send them overseas.
cheers, Rod... in OZ

ok, just to clarify, i know this has been asked before but i haven't
been able to find any clear answer so maybe you have a suggestion.
how much boost is safe to run on a 1992 legacy turbo(us spec, closed
deck engine) with no intercooler? i'd love to fit an intercooler but
i just can't seem to find any room.
