HKS EVC 6 How To?

phunk

Guys... This is real easy.

EVC solenoid has 3 vacuum ports on it.

Port 1: internal map sensor. (Boost/vacuum sensor)
Port 2: wastegate reference in (from manifold)
Port 3: wastegate reference out (to wastegates)

So the hks manual says to Tee in port 1 off the fuel pressure regulator line. It's merely a suggestions, it doesn't matter at all. So long as it ends up seeing manifold pressure. On a 350/370/g37/etc you couldn't do it this way if you wanted.. The regulator is in the gas tank and has no vacuum reference to tap.

Here's the thing about port 1 guys... For 10 years I have been hooking up port 1 to Tee into port 2, right at the solenoid. Cause its the same ****. It works fine, controls my boost to .1-.2 repeatability.

As for the wiring.. Power and ground and your set, you got boost controlling.

If you want boost by speed, you will need to hook up the speed wire.
If you want a scramble boost switch, hook one up.

Always make sure the boost controller settings are set for "actuator type" if you are only using the side port of external gates and leaving the top ports open. Or external type if you're using both ports on the gate. This is important or boost will sky rocket when you test it.
