Hi guys ,its been a while i havent posted here, i need your help. i installed my VI kit on one of my friends 1999 maxima. i double and tripled checked every wire and i just cant get the VI opening with the V-afc2. i checked every wire, every settings in the vafc2 menu. all is fine.

the problem is that i know there is a difference between the 1995-1998 pinouts and the 1999 pinout due to emissions and stuff like that. i just cant find the two different wirind diagrams, could you find those for me.

the ''friend'' is very impatient to get it to work but he doesnt even know what engine is in his car. imagine trying to explain the whole assembly procedure to someone who doesnt even understand...

I just want to get it to open and close with the v-tec feature in the v-afc2. i used the pink wire with the plug underneat the vacuum nipple on the vi.
its my 4th VI install.

help me.

 

from what ive gathered, sounds like your right on track with your wiring. I also heard on this forum that their is not an accurate pin out for the 99's. Ill look around and see if i can find on for you.

 

i've done over 15 00vi installs..

99's are no different from the other maximas...

only difference is electronic evap and electronic EGR... but.. EGR is not touched, and evap has nothing to do with 00vi activation.. just the way components are mounted..

make sure you have NO VACUUM going into the VIAS nipple on the manifold (Ambient Air)

I would first check that V-afc2 is set to 5000 rpm L->H vtec
i would check that the +12v is given out on the vias plug with multimeter and i would follow up with the actual Power Rod and VIAS cup check on the 00vi Manifold itself last.

I even had an issue where the BLACK VIAS solenoid was messed up, so i ended switching it out with the BROWN swirl valve solenoid next to it since it wasn't used, i just swapped and used a brown clip..

 

One thing I would do is maybe try hooking it up to a manual switch just to make sure theres no electical problems with the VIAS plug.

 

i hooked a direct vacuum source from the right most nipple. (the one blocked with a grommet) its sucking air directly and keeping the vias opened all the time. What you mean "make sure you have no vacuum into the vias nipple on the manifold (ambient air)"?? dont plug any vacuum source on the solenoid??
i used to take the vacuum source on my cold air intake before the throttle and it worked fine.

that 2000 VI doesnt have the brown swirl valve actuator so i cant switch the two to make sure it the solenoid that is fried... the rod actuates and the cup seams all good to me after checkup. i hooked the two red wires on the same wire while doing the vafc2 hookup.

 

Thats your problem take that vacuum hose off.

 

i just block if off!?! how the vacuum will be applied to get the rod actuated!?!

is it internally fed?!?
so, i hook one wire on the bottom connector to a chassis ground and the other to the pink wire on the vafc2. i remember mine worked with a vacuum hooked on the cold air intake before the throttle. i mash the gas wait to 5000rpm and the rod moves.

 

all right, im going to try it and gonna post the results. My buddy is freaking mad at me because he saw the car completely torn apart just to not activate after. he doenst understand the research and development part of tuning. sadly for me i fix it but each time i try to check the wires on the ecu, grounds, 12v, vacuum, connectors,... he bugs me a lot.

 

yes, NO VACUUM to VIAS nipple (hose from air in intake has no vacuum).. Otherwise the vi is ALWAYS open... and you lose all your lowend..

this is what your setup should look like.. nothing on VIAS nipple

 

The rod doesnt need vacuum to move if your using the vafc-2. The vafc-2 moves it electronically. IIRC the green wire connects to the pink wire on the vafc-2 and the other goes to a power source. I connected mine directly to my battery.

 

 

RIGHT, THANKS, im going to try it first then gonna post results. but, one thing, the rightmost nipple is opened too? doesnt it change your idle... maybe not after all, it never tried it...

 

Nope no change in idle.

 

Tell him to STFU and leave you alone or to do it his damn self, I know EXACTLY what you mean when someone who is clueless keeps pestering you, with car repair patience is an incredible skill that only comes with experience

 

it would be so soothing to tell him that but he got 3000$ worth of upgrades that i had collecting dust in the locker. i TOTALLY understand the karma it could give me though...lol

 

Did you get it to work?

 

VADIM COME TO SF TO HELP ME DO MINE!

 

hmmmm vadim did my 00vi last yr and never had no problems because of him i got a de-k swap

 

does a de-k run just like a de with a 00vi?

 

Not quite different intake cams and slightly different exhaust cams
00VI w/de will probably feel faster than de-k
