HKS EVC 6 How To?
I am in the process of doing a BP kit install. I currently have the HKS EVC 6 sitting here and looking over the instructions. I am more than confused when comparing the pieces to what is shown in the manual.
There is a brown wire that is supposed to be for "scramble boost activation"... do I have to hook it up or can i leave it unattached? It also wants me to T off the fuel pressure line. Is that normal? Where would I T it off? Also, does anyone have a picture of the wiring to the ECU? I need to connect it to the "throttle signal line" and "engine RPM or speed signal line". Or does anyone know where those wires are at and/or recommend a spot to tap those two wires? Anyone have any comments or recommendations as to how to do this install? Thanks Last edited by Cell; 08-23-2013 at 02:07 AM. |

Nooo... Nooonnooonooo, that's your main fuel line. Our cars don't have a vacuum line on the fuel pressure regulator because our cars use a return-less fuel system (the fuel pressure regulator is on your fuel pump in the fuel tank). The vacuum hose you need to T off of will be the one that you tapped in your intake plenum that plugs into the blow off valve. Essentially you want a vacuum source after your throttles.
You don't need to wire a scramble switch, nor do you need to wire the RPM/vehicle speed sensor/throttle signal wire if you don't want to use these features. Just tuck them away so they don't short on anything. Hopes this helps. |

I Have the HKS EVC 6 also. The directions need to be revised for more setups. Especially TT setups.

IIRC, the MBC boost source on my car is tapped to the passenger side intake pipe. In this case, the boost source goes to the control valve input. The wastegates are tied together with a T fitting, and a single line goes to the control valve output.

If you want to tap the signal wires from your ECU, you'll need to look up the harness in the service manual. You might want to ask around about compatibility, first.

Yea, I asked around about it already. Was told to leave the speed/rpm and throttle signal alone. I was also told that the scramble boost also is useless because of VVEL causing boost to fluctuate. Honestly I may just end up using the EVC6 for it's basic functions.

I have all the diagrams for this. Before I found out that you don't have to hook them up if your not using scramble mode. But defiantly ask if you go that route.

How about setting boost pressure according to engine RPM or load and gear selection? That's the only use I'd like to have over the scramble option.
It would be nice to keep the wastegates closed longer for better response, but limit maximum power in the lower gears. On second thought, 450 whp in 1st and 2nd is still relatively easy to handle [with new tires].

I think I figured something out with a little help from another member here lol...
What the manual calls a fuel pressure regulator may actually be the blow off valve. I could be wrong because of how the pictures look. It just looks wrong for some reason. |
