hey i was wondering how benificial everyone thinks the apexi safc / safc II is for an N/A 300zx 5spd? cause im fairly confident i want one, but i was wondering what everyone thought. im curious.thanks all

 

I don't think it's very beneficial at all.

They're good for tuning the car, but if you're asking this question, I really don't think you should be tuning your own car.

They're good for splicing MAF sensor signals on dual-pop intake cars, but you'll never have a use for that on a non-turbo.

Really, the only thing I could see you using one as is a fancy, overly-expensive gauge. (I will admit, though, that I LOVE being able to set my Apex-i AVC/R to monitor RPM, Injector Duty Cycle, speed, and everything else that units like the S-AVC/R and S-AFC are able to monitor... I just don't think that the usefulness outweighs the cost for a non-turbo Z).

And seeing from your other post that you really want an HKS Hi-Power exhaust, just spend the money on that, because it'll be much more beneficial to you to have a great cat-back like the HKS instead of a tuning tool like an Apex-i S-AFC.

 

From what I've been seeing, they're good for around 20 w.h.p. when properly dialed in. You'd need to go to a dyno shop where, either yourself or the dyno guy, would need to know how to dial it in. I've seen dyno charts in the 202 - 207 w.h.p. range with SAFC, intake and exhaust. iirc, we're 170 - 180 w.h.p. stock.

I would see someone actually hurting performance without the proper dial in.

I've been watching them on ebay, and will get a used one for around $150.

 

well i want this cuase i can get it basically for free...so id be stupid not to get it right? i just wanted input not like practicality of spending 300 dollars on one cuase right now thats not an issue with me.

 

I m thinkin about getting one..especially since it can display the 02 sensor readouts. I would get it. Now where are you goin to mount it though? I m curious..

 

So what part of the input did you not get??????? That there's a potential 20 w.h.p. increase?????? That's awesone that you can get one for free....... I wish I had your connections.

 

my bad i worded that wrong, it was to z lover who said put the money toward the exhaust...i forgot to mention money wasnt an issue this time i got what u said though canyon carver. adn i would mount it where the middle speaker goes...if it fits...other wise id put it in the clove bompartment or u can by the mounts for them they prop up on hte dash.

 

are you aware that unless you have wideband O2 sensors, that's an ENTIRELY useless function since the OEM narrowband O2 sensors don't assign a number value to the rich/lean conditions?

 

adn i got my dsm friends that tune them amazingly i wouldnt do it myself...that or i could have it dyno tuned by a pro. but yeah i didnt intend on doin it by myself cause i wouldnt know how in the first place id be doin HW for a long time...and even then im the type of person who doesnt trust themselves

 

OH..i thought they offered wide band and narrow band versions.

 

The ones that are on your car from the factory are narrowband... monitoring those won't do sh*t. You'd have to buy wideband O2 sensors and monitor those.
