I just resently got a 3.5" LR MAF housing and i will be installing this as soon as i can figure out where on the VAFCII is the in and out setting, i was sitting the parking lot at work today and said im going to look through the entire setting for this in and out setting, unless there is something i overlooked i just never found the setting, so that stalled me from installing the MAF cause if my calculations is correct it should be a 89" MAF housing and im sure there will need to be fuel added at idle and else where also the setting should be 1in 17out on the VAFCII but i cant find it, somebody help please, i will write down every seeting of my VAFCII most likely tomorrow

 

Thanks fellas I found it

 

should be 4 in 4 out normally. unless you have a bigger bore MAF than usual.

 

Dude, if this was solved I would know the answer. It hasn't been.

The SAFCII is 1/17 .. the VAFC, IIRC does not have that many options.

And It's actually 82mm.

Been through this a few times. Try using the largest contrast of engine sizes (D15 to J35) which is 3/6.

 

none worked

 

i just put the stock MAF back on... its on 1in and 1out now... none idle good

 

I would set a day aside, pick the largest difference, and if that isnt lean enough, tune it the rest of the way yourself, which you CAN do.

 

But he has no WB.

 

Bigger MAF with no Wideband?? Easy way to blow your motor.

 

oh. well thats step one after you get a vafc anyway so...

 

what about this???

You can't tune without a wideband, and you need one that datalogs that way you can use the numbers to tune.

 

couldnt i go off the gauge???

 

How will you tune it for different rpm intervals? unless you watch it and write it down or something while your driving or have someone else do it actually I dont think you'll be able to do it yourself while driving.

 

i think im getting how this thing works... so with the digital meter i just go til redline in lets say 3rd gear then it will save the data all through the RPM's or something then i go through and make the adjustment on the VAFC after??? how will i tune with the meter??? im new to this so bare with me

 

sorry to steal your thread but what are the stock in out settings for a 5.5 gen with a vafc 2?

 

Doesn't matter, as long as it's the same.

 

was that a sarcastic remark ? because the car idles lumpy on 1/1 but using 1/17 its slightly better.. but jumps around alot...

 

The VAFC doesn't go to 17.


Are you sure you're not using a larger MAF housing and a SAFCII? Because those are obviously the settings for it as seen in this thread.

im using an apexi neo.. In all honesty I've used the search function and if the question can be answered it will solve alot peoples guesses and problems... What is the in and out settings on an apexi neo for a 2003 maxima with stock maf?

 

Do you have a WB and is your MAF stock size?

 

yes i have a stock maf and yes i have a wideband.. and it reads extremely lean or goes extremely riched based upon the maf settings.. When I change the in and out the car cuts off or idles differently... The car idled best on in 1 out 17 but was still very lumpy...

I see from the thread you posted 17 is the correct out but what is the correct in... ?

 

Well first things first.

Do you have the manual for it and if so, have you read through it to find the relative settings? The 1/17 is for a 5.5 gen using a Q45 MAF(1 is Q45, 17 is 5.5 Gen Maxima). That is for the SAFCII.

 

i checked the apexi website cudnt seem to find anything.. prior to you having the q45 maf wat were your settings?

 

17/17

 

^ you just added to this forum tremendously.. thats what everyone needed to know.. thank you

 

Not really, we already pretty much knew that ( as I had always suspected, the Neo would be the same as the SAFCII WRT IN/OUTS), it's the VAFCII that still lies a mystery when coupled with the LRMAF.

What would be nice to know if the NEO can be 'manipulated' as the VAFC and have 2 maps combined into 1.

 

I don't believe so nor do I know the exact method of how to go about doing it... How is it done on the vafc2

 

If this is true for the NEO, it would then make it a, I believe, 16x2 map.

As for your other question...:

Use the the setting 1 In and 4 Out. VAFCII only go to 15.

 

Hmm so NEO>VAFC-II? 32 tuning point instead of 24 hmm.

 

$400 price tag makes it an epic fail in my book... EB can be had for less. Too bad they discontinued it...

 

Yeah you're right. I didnt realize it cost that much.

 

NEO does have ease of installation on it's side, and shopping around males it cheaper.

 

True, but as far as instalation goes, the extra 24 wires only belong to the 6 injectors and 6 coilpacks. (IN/OUT for each) And it's only 12 wires if you opt against using the coilpack harness. All 6 injector wires are right next to eaxh other and you have to cut/intercept these which IMO is way easier than splicing. But that is also just personal opinion.
