i need to tune my car, i can feel a difference that i dont like lately that my car is just sluggish. now do i really need to spend all the money on a utec and tune just to get more out of my car, and bring it back up to its potential?
my friend has a brand new apexi neo (there newest afc) hell let go for cheap to me

my mods: jwt popcharger, 5/16" plenum spacer, strup test-pipes, soon putting nismo exhaust on,

im not so much looking for a comparo of utec and this "neo" just to see if you guys who know alot about tuning these cars and the options to do so think that this things worth it.

 

Im in the same boat as you and not sure what to get. I think I decided on the neo. I have seen it several places for less than $350 with free shipping. Are you paying that price or getting a better deal?

 

my friend said 275, i could stretch that out over a while too.

 

Utec will be an overkill for you. Apexi or Emanage will good enough. I have a Utec and when I had my car tuned for Noz, we did an NA map and it only gained me 12hp more. For $700 plus for an NA car................... sorry.

 

Hook me up with a neo over time too? . Cheapest Ive seen was $299 shipped.Ive got $150 I can send now.

 

I'd get the utec so you can mess with timing also. Neo only does A/F, correct?

 

How much can you adjjust the timing? The neo is less than $300 while the utec is what like $800. Not worth it if your not going FI.

 

dammit, i had an emanage from my last car too but sold it.

no lemans i cannot hook u up. this kid bought my rims off me like 2 months ago for 800 and has given me 400 so far so ill do the same to him haha.


as for timing, eh...i know to really tune a car a/f isnt enough but ill just adjust my distributor for timing..lol jk ill sacrifice it for convenience tho. maybe first ill install the wideband i have and see if the a/f's are even off.

 

If you know how to tune i say go ahead, but if you don`t Osiris from Uprev is your best option, BTW Air Fuel isn`t Everything, you have to retard the timing a little as its more advanced from the factory because its TOO rich up top.

 

the SAFC, Neo or not, is an utter waste of time on a Z...you will, at best, be able to make very very small corrections, and if anything larger is attempted, the stock ecu will absolutely correct around it. Not to mention, you'll be cutting up your factory harness to get it installed...that, and the miniscule corrections you'll be able to do, make it a waste of money for these cars, even if it were $100

A UTEC can be had used for a very very good deal, and unlike the $300 neo, it will grow with you as you do future mods. Your $300 Neo AFC will end up as a small box with blinkey blinkey lights- I guess that's cool if you're into that sorta thing.

Netshark - sorry, but what are you talking about? Retard the timing because its running too rich up top? Please tell me that was just a huge typo and edit/delete your post so people don't get confused with misinformation

 

Sorry to but in but I asked a similiar question in another thread. I have a maxima and is the utec the way to go?

 

AFAIK, the UTEC won't work on a Maxima

 

So Im stuck with a neo or emanage?

 

I would think the Emanage Ultimate would be your best bet, or a reflash. best bet is seeing what people use on the maxima forums

 

Yeah I have and its sems very limitied for the 07 at this point. Wiring diagrams are not all that great and most have to have alot of knowledge as what to do.I dont have very knowledable shops where Im at , or that Ive found so I guess Ill wait alittle longer.

 

I dunno but when i`ve tried to tune my car first thing i`ve done is logging the car with Stock mode aka Map 0, the logging shows 27 Degrees of timing at 6500RPM with 11.4 AFR, when you lean the AFR to 12.5 or 13 and sets the Timing to ECU, the stock ECU still thinks that the car is running at 11.4 AFR, anyway when i did it i got a knock because timing was 27 and the AFR was 13 or 12.7.

What i`ve been told is that when you advance the car and richen it up it won`t knock even if its too advanced, but when you take out alot of fuel (leaning it) you have to retard the timing a little so it won`t knock.

Am i right or wrong ? am still learning i`ve attempted to tune my car 2 times first time i got it working a little 2nd time i`ve messed things up because i was not in the mood to tune :P

 

im very familiar with piggybacks and the drawback that ultimately it is just playing tug of war with your ecu where you make adjustments. i have absolutely no problem doing any extent of wiring. but it is becoming clear to me that the neo just isnt gonna cut it, i think ill begin AT LEAST looking into comparing things like emanage and utec where i can tune timing as well as fuel.

 

ok first of all, i think netshark has the AFR backwards, the lower the number , the richer it is...


second of all, the apex neo WILL get corrected by the stock ecu. we have dyno tested this twice on two different cars. we fully tuned them, let them go two weeks. then redynoed them. both cars lost hp over the original hp.

sure we gained 10 or so hp on the dyno, BUT we lost it when the stock ecu took over.

 

Would the emanage work better?

 

Save your money and just get the UTEC. Do it right the first time.
