I am putting an 00VI on my 95 maxima. I have printed out Jime's wiring instructions for a SAFCII...from what I have found these are the same instructions I can use for the VAFCII...is this correct? Also, which wire do I hook to VAIS on the 00VI? Finally I am planning on using 5th gen injectors in the rear so this will make my car run a little rich. I am running a JWT ecu and I would like to be able to make fuel corrections on the VAFC to correct the rich sitiuation that would be cause from the larger injectors. Can this work? From what I have read some people said it would not help anything and others said that it should not be done since JWT has adjusted the timing in there program. Any help you can give me with this sitiuation is appreciated.

 

Yes.


Yes.

 

so the JWT ecu will not over ride corrections made? Which wire do I hook to the manifold? Thanks for your help.

 

There are other threads, but this one proves it just as good as any other.

VAFC wire color: Pink

I dont think its a good idea to run two different size injectors for each bank of the engine. You'll have uneven mixtures bet'n the two banks. I would just either stick to all 4th gen injectors, or all 5th gen injectors.

But even so, why change the injectors for the purpose of running richer? Thats what the VAFC if for

 

He won't be able to anyways...
Wondering if he meant 5th gen coils in the rear

 

Pretty sure that is what he means, in which case he shouldn't have any problems.

 

Damnit. I didn't catch that. VAFC will only control MAF signal, and not injector pulse.

EU can control injectors, don't do it. Jut find 3 cheap like injectors.

 

yes he will be using 5th gen rear coilpacks and all 6 5th gen injectors. Carson you could've just asked me which wire to hook up to the VIAS from the VAFC.

 

Yeah Carson, ask Jason next time.

Glad things will work out. It will be an interesting dyno.

 

this guy has good advice.



haha but yea he is buying the stuff from me (for a sweet deal might i add) and i had it up and running on my car, which the idle is still messed up on.



Ps- Carson, I didn't get a tracking number when i shipped out that VAFC but it will be there sometime tomorrow. sorry about that.

 

just remember there's no 'knock sensor' wire hookup needed

 

hahahahha....sorry I get bored at work and start asking questions But I did really want to know about tuning with a VAFC while using a JWT ecu.

Thanks for all the advice

 

should be able to do it. i have the vafc hooked up and a jwt ecu, but i still have my maf wire unspliced...... i'll wait until i actually have time to mess w/ the vafc and tune before i do that.

 

the vafc is now in the car and the car is still running so that's a good sign. Hopefully the 00VI will be on next weekend and I can start tuning. Does anyone have recomended settings for the VAFC (i.e. minus what percentage to comensate for the larger injectors) that could get my by until I get to the dyno?

 

It's best not to play w/ those parameters until you have an accurate away of reading AFR.

Have you looked into getting a wb?

 

No but I probably should since I have two maximas that will require tuning. Any advice on which ones to look at?

 

i have a Zeitronix zt-2.....

 

Plx R300 .
