Re: Failsafe with HKS EVC 6
The aquamist failsafe relay contact is "closed" when flow is normal. So the MAC valve is "energised" during a normal cruise and on boost conditions. Ie, port 1 &2 is connected. Diverting the boost into the HKS capsule, allowing it to control boost.
As soon as flow problem is detected, the relay contact goes "open circuit" and de-energises the MAC valve. Now the port 2 & 3 is connected. Directing the boost into the upper part of wastegate actuator resulting in dropping boost.
I will looking into this closely tomorrow. It is getting quite late here.
