So i decided to change my plugs, and to make a long story short im running very rich. What could i do to correct this. What would you guys reccomend for something to tune a/f ratios along with something that will open up my variable intake. My friend said the vafc2 isnt something he would reccomend.

 

gtr rider "Under normal conditions you wont notice a thing.. I do however notice a difference between WOT and 3/4 throttle w/o a fuel tune"

 

the de-k has larger injectors I believe so if ur using a 4th gen ECU its calibratiing for smaller injectors...so lets say at 3 bar of fuel pressure the 4th gen ECu thinks u need more fuel under WOT cause it does not rely on the 02s to give fuel readings...it uses its preprogrammed settings which are for smaller injectors....all u need to do is get S/VAFC or AFPR prferably both to tune so ur not rich under WOT...cause thats where most of ur excess fuel is comming from

 

adjustable fuel pressure regulator? i have a dek also..also running rich, I just bought a vafc2 to tune with and to open the vi..I would recomend getting one. does your friend have one that doesnt recomend it? does it work? not sure y he would say not to get it...I will also be getting a wbo2. I get a backfire when i let off above 3.5k rpms. I will let you know if the vafc2 fixes this problem

 

the VC2 will fix it the rich conditions to a point....the AFPR just allows for more options like timing advance

 

what do you mean to a point? I just dont want a backfire anymore. you can advance timing with an afpr?! where can I read up on that?

 

its called the all motor section....the VAFC can correct fuel to i think 50 +/- Factory settings...which should be plenty...thats the point i meant....and yes raised fuel pressure and taking out fuel will advance timing

 

thank you for informing me to read in the all motor section. That helped a lot. I didnt appreciate your tone.

Found a thread tho. http://forums.maxima.org/showthread.php?t=434821

Wha', you didn't like the EVO5s?

 

anytime you change to bigger fuel injectors, you need to have the mass air calibrated for the bigger fuel injectors. I did this on my 5.0

 

You don't have to. You could just buy an AFC and 'tune' from there.

 

(GTFO.. SSR was bought out last I heard btw.. 16x8's I had were like in the 12lb range I think.)



GET THE DAMN VAFC AND CONTROL YOUR CARS INNER URGE TO SPRAY UN-NEEDED FUEL.

 

Mine aren't SSR... SSR's look better than mine and are a smidge lighter..IMO.

Mine are 17x8 14.3lbs

 

OT: (I know this, they're Motegi's.. All I'm saying is a response to you inquiring in that thread about SSR Comps)

 

i dont appreciate not using the search the function.....but anyway...glad we could help
