VAFCII in and out setting... where???
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
I found it

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.

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

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.

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.

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.

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

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.
