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.

Hey Richard, I'm reviving this from the Dead
I'm now in the final stages of my setup (Finally) and i want to add the failsafe into the setup, I rely on the water injection to work in order to achieve the timing i have set, so in the event it stops working i need to make sure boost drops quick.
Reading through the diagram, i'm alittle confused, With the EVC6 and an external wastegate
O = Direct to Top port on EWG
I = Direct to Bottom port on EWG with "T" to Turbo/boost pipe
With the instructions earlier on, you saying when there is an issue the MAC valve will turn off and air will pass from the Turbo to "O" which goes to the TOP port on the EWG, but if pressure is applied from the TOP this will shut the gate cause boost to be uncontrollable. in the event of a failure, Ideally Zero air must flow to the top port and all must go to the bottom port force the gate to open at spring pressure.
Possibly i miss-read the diagram or instructions?
Would it be possible to do a diagram from this illustration (Attached) ?
I'm assuming you still keep a similar plumbing configuration but add the Mac valve in to bypass pressure in the event of an issue on the Aquamist unit.
Thanks!
