what are the reviews on this... is it worth it or any good?. if anyone has it how do you like it and was it hard to instal..

I'm just looking for any info on it because it looks like a good air/fuel tunning tool.

 

I used it, but on a Honda. It works awesome.

 

how did you hook it up and tune it?

 

It's hooked-up to your computers wiring harness just like e-manage,ss box etc... then you punch in the #'s and off to get tuned. Honda has a bigger after market than Nissan on their forum you can get the #'s for the safc. Enough to get you to get tuned. I wouldn't trust somebody elses tune everyones car is different.

 

Its a nice lille gizmo. It intercepts MAF readings, so ECU is tricked into adding more/less fuel, to make good A/F mixture. As simple as that.

 

I still have the manual for a v-afac. From what i remember it was staight forward. Hope this helps.

 

does it display air/fuel in current time and have a playback? also i'm just wondering if i use this correctly would it be like a mini re-flash?.

and when i looked at them it is not model specific so does that mean i would have to modify the harness?

also if this is so awsome why dont more people have it?

 

no air fuel feedback..you can moniter one of the factory 02 sensors, but that's all. Also does knock monitering

Why more people dont use it is because the factory ecu seems something is up with the MAF signal and tends to adjust around what it sees, thus negating lots of the changes you initially make

 

can you monitor the factory O2 with the tunner or you need another guage?...

also if the factory ecu changes around it then wouldn't it be pretty useless? or does it eventually learn the new program

 

you can moniter the 02 sensor right on the SAFC2 screen.

On some cars teh SAFC2 works great..I just have not found this car to be one of them

 

is anyone coming out with something where you can program these settings more efficiently...either piggy or stand alone?

 

Great, I just ordered this and now I see this post. :/ Imma have the boys at my local shop see what they can do. I called em beforehand and they said it should work all it needs is a tach adapter to read the rpms correctly. *crosses fingers*

 

So the factory ECU pretty much overrides this? This was going to be my next purchase.

 

tach adapter? for what

 

They said with the 350Z and the S-AFC the tachometer wont work correctly so you need a tach adapter so the gauge works.

 

got one; it's gettin installed in 2 days. i think it will work fine.

 

Cool. Tell me how it goes. I am getting mine in a week or so... damn ground shipping. I should have it installed soon after. A very reputable shop down here in miami is doing it for me so hopefully everything goes fine.

 

well, i'm not gettin it tuned until i get my cat problems fixed. my kinetix cats r givin me fits, so i'm havin them taken off. then i have to decide if i want to send them back or try another brand.

 

I hear Crawford's are great.

 

let me know if you need a tach adapter and how the instal went.
