Simple question needing a answer too. I am currently thinking of taking stock intanke manifold off and taking it to a performance shop here in MN to see if the can make a bigger better flowing intake manifold. Just need to know how it is activated.

 

ECU provides ground at ~5000rpm.

 

Do you think I would get a CEL if I wouldn't use it and used a solenoid hooked up to my RSM to activate at any RPM I want. Of coarse I haven't taken apart my intake manifold yet so I don't know how big the powervalve actually is.

 

You won't get a CEL, there is no feedback.

You don't need to use a solenoid, but maybe a relay. I doubt it though, since the RSM should be able to handle the load.

If you want to make the VIAS switch sooner the 5000rpm, I'd just tap the ground wire from the ECU to the RSM. That way the RSM will provide the ground sooner and then at 5000rpm the ECU will provide ground, which won't do anything. However, if you want it to open later then 5000rpm, you'll need to cut/splice the ground wire to the ECU and the RSM will be in control.

 

What's an RSM..? Is the valve in the 00 VI turned by vacuum or a motor?

 

My Apex-i RSM Rev speed meter. It has a RPM and speed output so you can put in a rpm and it will turn it on.

 

Vacuum, however there is an electric solenoid that controls it.

 

So its basically like the MEVI?

 

Yes, except the MEVI has the 2ndary chamber above the runners vs. below and the DEK is made out of plastic.

Very similar, however I'd say the DEK is slightly improved.

 

ICE what's the color of the wire going to the ECU I might do some experimenting first. I still got ECU diagram from Kevin.

 

Looks like Red/Yellow is the 12V and the one you need to cut/splice is Yellow/Gray at least in my 2001 FSM which may be different.

Just use a multimeter to see which is which.

 

Does the 2000VI require a vacuum chamer like used on the MEVI.

 

Yes, but the vacuum chamber is incorporated into the 00vi design.

 

IIRC it has it's own internal vacuum canister.

 

So if I hook up a vacuum source to one of these I'm good to go?

 

is there a difference between the 00vi and 01vi?

 

00Cali and 01 should be the same, no EGR port.

 

Why are there two? Mine only has one and my friends 2000 and my other friends 01 only has one.

 

there is a difference. Mine is a 2000 fed spec and only has one vac line where it is circled. two lines means it's a cali spec. I asked this question once I did my blue vac lines why i had only one instead of two.

 

What I plan on doing is taking the wire that tells it to open at 5000-5200 and using my RSM to do a couple dyno runs to see if moving it would create any extra HP. I am thinking around 4000 rpm.

 

The second one is for the lower IM swirl valves.

 

I'm thinking the left one is the one I need for the power valve. Sound correct? So all I need is to hook up a vacuum line here then correct? Since I'm S/C'ed and won't have vacuum, but positive pressure, when the valve needs to actuate...

 

You will have vacuum. Every car gets some kinda vacuum at low throttle openings, boosted or not.

 

I know, but if it doesn't store the vacuum some where, there won't be any at high RPM when it needs it, that's what the canister is for IIRC.

 

You're right. But since the 00VI has it's own canister built in that won't be a problem.

 

it does? So it's just one vacuum line and a signal?

 

thread jackers J/K if this helps you out just carry on with conversation. What's the swirl valves? I don't have that second vac line.

 

Sorry about the jacking, I did kinda horn in a little. Anyway, thanks for the help guys. Now if it just gets above -5 I'll get out to the garage and do some work...

 

mine is missing the cover for the vacum line.... anyone knwo what this piece is called or a part number??

 

So from a MEVI setup, what would you use with the 00VI setup ?

That vacuum canister would not be used at all ??

So all I need is a rpm switch and a relay? I have I/H/E with no cats/UDP, do you think activating sooner would provide gains for me? If so what rpm?

 

4600rpm, so switchover occurs at 4700rpm from the dynos I've seen.

MEVI guys were using 5200 or so, but the DEK needs it sooner then the stock 5000rpm IMHO.

Yes, the vacuum canister is self contained, so you just need to provide a power wire and a switched ground(RPM switch) wire to work.

 

dumb question - but is the rpm switch opening or closing the butterfly at 5200 - and why 5200 - is it proven to be the best setting - and has anyone tried other settings and seen any better results.

 

On the DEK it is opening allowing all runners to share air from a secondary chamber/box.

Dynos.

 

should have been more specific - i meant on the mevi.... but i guess it's the same concept??

 

Yes IIRC, except the MEVI uses individual "butterflys" instead of a single long power valve(rod).

Both use a secondary chamber, but execution is different.

 

thanks for the input.

 

can someone explain how to hook up the rpm switch, what wire(color) do you tap into on the coil pack plug, and what wires for the power actuator go where , one for switched ground and one for power or ground(which colors)?

 

Thread resurrection. I'm curious about how and where the RPM switch connects too.

 

The power valve control solenoid has two wires, one goes to +12V and the other is to be supplied a ground at XXXXrpm.

I've never wired a RPM switch, however I have done my shift light and all it required was a +12V, ground, and a tap on the ECU-->tach wire, which I'd assume is the same plus another wire for a switched ground output that you supply to the PVCS.
