S-AFC safe/reliable on a S14 Zenki SR all stock other then Z32 maf?

[eastslider]

Hey Zilvians! My maf isn't working how it should and I tried looking on the net for a replacement and all I found were used mafs that look worse then my broken maf and selling for 150+...... But I did find a brand new Z32 maf for under 100$
New Mass Air Flow Sensor Meter MAF Fits 300zx J30 Z32 | eBay

my set up is 7psi no boost solenoid...
3" exhaust from turbo elbow
intake
FMIC

so stock.... i just want a good reliable daily driver thats not gonna blow up... please help me out with input if you guys read this, have a great day guys.

SAFC = garbage.

Good reliable setup that won't blow up is OEM MAFS on stock ECU tune.

[eastslider]

thx for the input i don't wanna run something that might blow my engine but would anyone know where i could buy a new zenki s14 sr20 maf?

[steve shadows]

SAFC are as reliable as how they were wired into the factory harness...which is usually horrible.

[iRONDONkey]

ROM tunes such as enthalpy

If getting a 'new' Z32 MAFS is the only option you think you have, then save your $$$ for a Power FC. You can wire a Z32 MAFS in and just select it as your default and the car will run perfectly without having to potentially dick up your settings. I'm sure there are other standalones that are just as user-friendly as well (Google search away).

Pretty sure you are not going to find a new S14 MAFS... also pretty sure that chances are fair-to-good that if a seller says a used one works, it prolly does- just make sure to check their feedback. I've bought a lot of stuff on Ebay and have had very good luck dealing with sellers. If you are not sure if something works, send them a message and ask. If they say it does- buy it and make sure you use Paypal... so you get buyer's protection. I think you are overthinking it. I understand you want a reliable setup. That being said, I think a used OEM MAFS is your best bet.

I run a safc Neo tuned. My car runs like stock and makes 346whp on a black top sr. If you go safc Neo make sure it's wires by a professional. All the negative comments about safc is because they did it themselves and fucked it up.

No moron, all the negative comments are because it can't control timing and is a useless piece of shit. Timing is what kills motors... Do some research before you speak out of your ass next time.

I know it doesn't control timing you stupid fuck, but it's obviously not worthless as you make it out to be. He's not building a god damn race car he's putting on a z32 and keeping boost levels stock. So why go power FC for that moron? Would be a waste of fucking money. Watch your damn tone kid.

X2 a lot cheaper then going power fc

SAFC is a great cheap way to tune your car, although enthalpy is about the same price.

the AFC, AFC NEO get bad reps on boards, mostly from sheep who have zero experience using the piggyback.

bottom line, if u have one use it. if you have 300ish burning a hole in your pocket, go enthalpy tune

[fliprayzin240sx]

I've had a SAFC, only thing its good for is to fine tune the rich fuel map you usually get from ROM tunes. Or like stated earlier, just to make MAF corrections for a Z-MAF.

OoOo, someone has their panties in a wad. I never mentioned a PFC idiot, an SAFC is a waste of money, any way to slice it. He can spend $349 on a ROM tune and be better off. No one keeps their car stock and a ROM tune will give him room to grow. An SAFC is a recipe for catastrophe...

I wasn't going to chime in, or defend the other guy, but you coming out and saying do some research, and that timing kills motors and that's the basis of a AFC being crap is ignorant.

If the OP has an existing AFC, use it. its not a ticking time bomb, or a "catastrophe" waiting to happen as some of you kids like to put it. It's a tuning device, and put in the wrong hands it will fuck shit up just like any other tuning device.

OP asked if a AFC is safe, the answer is a resounding yes.

Thank you for posting in a mature manor. I was going to get into more depth but I'm at work.

Op wants a quick simple solution. Safc-150 dollars. Z32 maf-70-100 dollars. Tune 200 an hour depending on shop. Only takes an hour for what you need.

Or get a tuning based rom ecu and have it tuned. In my opinion I would just find a sr s14 maf and call it a day I'm sure people on here are parting your exact motor.

What I'm getting at is he comes in here and throws around 346hp on an SAFC. Sure it's possible, but there are other factors to consider. I'm trying to protect the image that he protrayed. It is not ok to wire in an SAFC and go out and turn up the boost. Perhaps I got a little carried away and I apologize for the stab at him. Sure a MAF swap and SAFC should be fine, but people tend to take it further than that and it's not something that should be done. An SAFC is archaic at best and is not a very good "tuning tool". It is bare bones, fuel TRIM only and not full on tuning tool as some people tend to believe they are.

As far as an SAFC being safe, it depends on how he intends to use it. Boost up, larger MAF and stock injectors, not so much...

My car has been running one for a year now and no issues....hmmm

19 psi 346whp dd..hasn't blown up yet. Nice over exaggeration.

Sorry, but there's a whole lot of misinformation in what you are saying there.

Big injectors and bigger boost is exactly what the SAFC is for, and in no way would it be a detriment to the OP to use a AFC and turn up the boost unless he didn't know what he was doing.

Having tuned boosted cars since 1996, including the very first AFC I can tell you that a lot of what you are saying is misinformation.

MAF + AFC sucks? sure if you are venting to atmosphere. I would have no problem with someone coming out and saying that, or referring to airflow overrun, limited IPW or other such annoyances when it comes to the AFC.

But coming right out and just blasting it like you did doesn't do anyone justice. You have some points, but none that answer the OP's original question or the validity of an AFC on his SR.

[jr_ss]

I'll be honest and tell you I know nothing of the new units nor do I care to. I think piggy back fuel computers are a waste and obviously wouldn't recommend them to anyone.

Correct me if I'm wrong, but doesn't the SAFC 2 have a limit to the size of fuel injector if can control?

[eastslider]

I just wanted a alternate solution from getting a used s14 maf.. but hmm maybe just getting another used maf and pray that is cherry is the best route for me cause im just going to keep it stock boost... thanks guys for the input!!! I wish sr's came stock with MAP -.-

[Johnphen]

yes, you are right there's only so much correction range for the AFC.

its definitely not a time where you could honestly recommend an AFC to anyone, unless they are interested in BPU only kind of mods, or have an existing AFC laying about. tuning has come a long way since the piggyback age.

Can't we all just get along???



OP just needs a used S14/SR MAFS that works and he will have a DD that is about as reliable as can be. He doesn't need a new Z32 MAFS, and he doesn't need any potential points of failure tapped into his wiring.

That's what I was getting at. There is a small window of adjustments on the SAFC. You're limited by the unit and any one venturing outside of that window can be sure of a let down.

Alright, he could spend the money to buy an SAFC, the MAF and keep it stock, but over the course of my automotive endeavors, experience has taught me that it would be money wasted. He's limited by the tuning tool and would have to spend more money to get a "different" setup. I think that a ROM tune would serve him and his car better than, a potential wiring and "tuning" mishap by the end user. You really can't beat plug N play.

That's one issue I hate is my ssq being vented with the safc.

No, do not use a SAFC or a Z-32 maf on an OEM Setup.

The most reliable setup is the factory setup. Change anything is asking for problems.
