[?] '18 Intake Manifold on '15-'17

I Installed a 2018 ported manifold on today, I wired it the way pictured but I soldered them instead of crimping but I used the 2017 manifold runner solenoids and routed it like 2015-17. No codes as of yet but I feel As though it will because kinda stumbles on really low rpms like the runners aren't working but dam does she have some top end now.

Yeah that stumble is prolly the IMRCs not working on one side. Scan your car & you'll probably have a pending code.

I scanned my car didn't have any codes I'm gonna drive it around for a while and see if they kick on or not

Edit: yup got the same code P2005

i just drove mine with wired connected together on blue plugs and redid the connections i thought were bad and seems good to go even just holding the 1500 rpm and 2500 rpm steady no hiccups at all . sent the log in so well see what happens !

guy tried that and still threw codes . seems to be easiest to lock them out . guy has em locked out on facebook and picked up 45hp and lost like 4tq is all so crazy

Just need correct length bolts but this should get it.

If you delete the cmcv solenoid the black center piece doesn't need to be trimmed.. if you do it would need to be notched just slightly as well, so i'm leaving that part alone until I decide exactly what I want to do there.

You wouldn't need to clearance the back of the lower part as much if deleting the solenoid as well, but easy enough to give myself the option this way, that area cant be seen either way..

Contacted Scott Day and asked about vacuum line routing or a diagram, he said he was sending the diagram out to those who purchased the pigtail adapters so I just ordered some, got my original pigtails now today. Just more waiting. Looks like everyone is getting closer to a solution.

So you're going to post up that diagram once he sends it to you right?

That will be huge. I’ll be all over that and will likely get the pigtails too.

Did he confirm their setup is tested and doesn't throw codes?

Here is the vacuum diagram from Scott ! But mine is setup this way with the wiring diagram that is correct and somethin is still making my imrc stuck open . But no codes . I also wired my blue connectors together so we’ll see what happens when i hear back from lund !! It might be fixed after my last time ducking with it !

Doesn't show rear vacuum lines

That’s the vacuum diagram he sent me

I just talked to lund and they said my problem is fixed and imrcs are functioning and no codes or anything ! No rough idle car runs like a champ ! I ended up wiring the 2 blue plugs together . Each plug has a geeen wire you tie them together than one is while and the other is yellow tie them together and follow my pinout paper and that the vacuum line picture and everyone should be set !

On the 2018 the brake booster goes to the port he labeled as "needs vac source". The middle port he labeled for brake booster is for the line coming out of the intake tubing.
