Default Failsafe with HKS EVC 6

Hi all ...

I want to know how exactly to wire the failsafe of the hfs3 to work with an ebc using a stepper motor for boost control ( evc 6 in my case) ... With external WGs

The manual calls for the use of a 3 way MAC valve, but stops short of explaining exactly how ...

Do you set it (MAC valve) to divert the boost referance hose going into the "0" port?
Or set it to disturb (block) the actuator signal hose to the waste-gates "port 1"

My aim is to go down to spring boost upon failsafe activation ...

Many thanks in advance
