DE-K questions
Hey guys i searched and could not find the answer i was looking for. Partly because i do not know what im looking for. My DE-K is finished and tuned, and the power seems solid but its just not what i expected. The #'s were 190 tq at 4000 rpm and 170 hp at 5300 rpm. I was expecting close to 200 hp and 210 tq. I thought maybe one problem is the intake is not opening at all or partially. My mods are as follows Cattman header/y, stock cat, megan racing cat-back, short ram, and tuned with apexi neo. The motor has approximately 2000 miles. Any suggestions/opinions?
I know the org is known for its flamers but i searched, however im not sure what im searching for.

Just my thought its a little rich, I tune at about 13.5 to 14.5 (but I'm also crazy)
Alot of things can play factor, weather, gear of pull. but your dyno results seem about right.

Found this article. I dont know if theirs any truth about it.

If you're sure you have the VIAS activated properly and you're not making power up top, your VIAS might be busted. Check the 5th gen stickies for more info. I just fixed mine and it feels much better now.

from the looks of the graph it seems as if the variable intake isn't working....i would think horsepower wouldn't decrease that much if it was working properly....
have any pictures of how its wired up?
edit: that dyno looks a little weird to me...i had similar dyno troubles this summer....i don't know if that dyno is showing accurately what your making......looks waaaay off.

They said the dyno was calibrated last week, but who knows. They have a "1500" hp drag car thats constantly on it. So after reading this thread and a couple of others, Im 90% sure my VIAS isnt hooked up at all. Im going to do the VIAS fix if needed today.
My next question is, my NEO has a v-tec function. I was going to use it to control the 00VI, but im not at all sure how to wire it up, or if i need some sort of mechanical switch that will activate my VIAS. Any info on this?

Ok so i checked the "cup" inside the brick that attaches to the intake and its in tacked and not loose. So thankfully i dont have to worry about that for a while.
From what i understand from my friend who has done this swap (i30dvr) Power should be hooked up to one of these plugs and the NEO to the other. (plugs boxed in red)
with those hooked up the neo should tell the solenoid to open through vacuum pressure. I have three Vac lines coming off the "brick". two of the lines connect at a Y and go to nothing. as shown here.
the other one comes off the "brick" and goes to the brass hard line and then continues into the abyss of my motor haha. Shown here in two pics.
Please Correct me if im wrong, or tell me if im missing something. Id like to have my VIAS working soon.

Ok so ive checked to see if the VIAS was busted and Check to see if the vacuum works with this trick http://www.youtube.com/watch?v=hFimhXYnIaw. Both are fine. If anyone has info on hooking the Vtec feature of VAFC's to the 00VI, please let me know. I read through Caesars Chariot sticky, but 90% of the links are dead. The thread did give me a clear understanding of the vacuum lines however.

I have the V-AFCII hooked up and properly activating my 00vi. I'll try to look at what wires need to be hooked up..
IIRC, it's only the black plug you need to worry about. One wire to ground, the other to one of the vtec wires of the V-AFCII.
AND, you don't need vacuum to any of the nipples...just let them sit there hoseless.

Another thing I've read...it's silly to compare your dyno numbers to other cars. There are too many variables from one dyno to another, and the operator himself could change A LOT of things.
The only use for dynos is for tuning and measuring performance gains. Theoretically you'd go back to the same dyno each time with the same operator using the same settings and same weather conditions. This way you can accuratly gauge gains by comparing your previous runs. You may be making good power, but this dyno/operator is is resulting in a "low" reading. It does look a little funny though...and why didn't you ride it till the limiter?

mowgli29, if you could get pics and description of how you wired the 00VI that would be great! I have a video of the best dyno run uploading to you tube. I will post it soon. It sounds to me like hes taking the car right to red line and holding it there for a second or two, but also it seems like its being smothered up top.

Also if someone has the Layout of the 2000-01 VIAS layout with part numbers, could you post a link or pic please. My motor did not come with the plug that goes into the black receptacle for the 00VI. Id like to show what im talking about to the nissan parts people when i pick one up.

those are the best I have. no part numberts, but I would think the parts dept can relate it to their system and find part numbers...
you need the connector for F29, VIAS control solenoid valve.
still working on wiring info.

VIAS wiring: of the two connectors, we want to use the LEFT one that is BLACK. forget about the brown one on the right.
then on that plug there are two wires: left-red/yellow and right yellow/green.
the left wire goes to the pink wire of the V-ACFII
the right wire goes to a ground.
I think I have an extra connector if you can't get one from the stealership.

This is the same set up I have. You VIAS is not hooked up, that's why you are not making power. I did a dyno pull with mine closed to find the poper place for my switch over point, and the graph turned out just like yours is now. Once I set my switch over point and hooked up the VAFC-II My peak HP numbers went up quite a bit. With the VAFCII you just have to hook up the V-tec wire to the hot lead on the VIAS plug then ground the other one and it works. If you still need help at the meet I can possibly look at it then.
Also you took a pic of all of those vac nipples with hoses coming off of them...those don't really matter, mine are not hooked to anything.

IIRC, having one nipple(not sure which one...maybe it was both
) hooked up to vacuum will result in an always open VIAS. Easiest way to avoid this is to leave them hoseless.

Thanks for all the help guys! Now ive got to figure out why im leaning out above 3 grand below and above 50% throttle. I talked to the Mechanic who wired the NEO (Cardana im running the Apexi NEO) up, and he said the connections were soldered on. The car went into limp mode, I cleared the codes, then started to run lean. The mechanic said the ECU might be going through a relearn process.

I assume you are using the stock ECU and not the DEK ecu right?

I don't know much about the NEO but I am guessing it is something like the VAFCII, I also have had an SAFCII and it is wired very similar. Do you even have any wires going to your plugs for the VIAS? What I am getting at is it looks like it is not even hooked up...maybe I just don't see the wires.

As far as my car just leaning out i took it to the shop, and the mechanic was baffled. He said that the only time hes seen something like this was with VW's. He also said that you will just have to tune it when the wideband goes lean or rich.

So that is why you are not making power...your VAIS is not opening because your neo is not hooked up.

He had nothing controlling the VIAS. The black connector pictured about, it needs to have 12v running through it post 5k (In his case, possibly 5250 
). There is a wealth of information here on how to configure an '00vi swap.

Yeah i have it figured out, just not the time to mess with it right now, Ive gotta do oil change, alignment, and figure out why my clutch loses pressure with out losing fluid.
