i would just remove the ground signal from the Egr solenoid coming from the ECU and bring that to a different solenoid. As Mat said, you need to disable the EGR in the Nistune software and use the ground signal on the EGR solenoid to trigger the mevi solenoid for vacuum. BTW you need a 3 port solenoid I believe. I have to look at mine and confirm but I ordered it from Nissan and it's also in the Mevi write up if I'm not mistaken.

Now this makes sense as Mat didn't explain it to me in that much detail. You bring 12v to the positive side of the solenoid and the ground is taken from the EGR solenoid ( your trigger output from Nistune at a set RPM) and EGR disbaled in Nistune. When it's time for emissions if needed switch it back to stock and enable EGR in software.

I have the GM one I think. Not sure if it works though.

Not sure about the GM one .. Can only tell you from what I used. I used the 3 port Nissan solenoid and It worked perfect with emanage ultimate trigger output.

I have a Delco Remy DR152 2250-1 3-port boost solenoid (aka "GM boost solenoid") and a vac canister that I have no idea what it is lol

I was thinking about using the EGR solenoid by cutting the power wire and hooking that to a 12v ignition source.

The EGR output is negative controlled. You change the wiring from the EGR to the VCT solenoid. The other end of the VCT solenoid is ignition switched 12V power. This activates the VCT solenoid when in certain load/rpm ranges.

EGR solenoid will no longer function once VCT is enabled. In the software you disable ‘EGR’ to use the output for VCT. You need to disconnect EGR solenoid and wire to VCT. Do not splice and run two solenoids from the single driver output! It would blow up the driver due to excessive current load.

If you need EGR for emissions later on, then swap the wire back and reenable the ‘EGR’ tickbox in the ‘feedback flags’ parameter in the software."

My ECU should be there tomorrow

I'm not understanding it in words. I need to see all this mumbo jumbo in an actual diagram to make sense of it.

^ That. And this? (Not 100% sure).

Help me figure this out ya bish.

EDIT: That EGR solenoid diagram I wrote up (not from Matt).

That's exactly what I'm trying to do. Just need to figure out how the vac lines will go.

Andy at AutoVaughn Performance got my ECU

The anticipation is killing me.

no different from setting it up with a gm niod you just need to swap the ports cause the gm niod is no vs nc where as the nissan niod is nc vs no or vise versa
