I been thinking in upgrading my fc non turbo !,i still trust all motor cars! i want to spend like 350 and i dont know what is better! The apexi saf-c or maybe getting a chip from Jet ? what do you guys think? Whats better?

Uhh that's a no brainer... safc for sure.

as far as i know even with the s-afc if you want to run
more than stock boost you need to chip, or the stock
computer will fuel cut at 8 or 9 psi.
I could be wrong about this just starting to play around
with a safc now...

I have no idea about the s-afc but I can tell you I loved my Jet Performance chip for my 86 N/A. Once I am done with my T2 conversion I will get another chip for the T2 ECU.

If you get the fuel cut defencer (a.k.a. FCD), it will prevent the computer from cutting the fuel.

White Seven you think the chip is worth the $400? How much HP gain you think you get? Does it cause any extra strain on the engine?

What JET chip are you talking about? As far as I know there are no chips available for FCs anymore. MCRacing? used to make a chip, but not anymore.


Go with the S-AFC, much better than a chip, because it allows detailed tuning.

does the chip do any more than the safc does (timing adjustment or anything like that)?

ive heard an safc on a stock port n/a wont benefit power at all, maybe just fuel economy.

anyone comment?

vectorminds

talking out of my *** here, cuz i havent done it yet... but im preety sure that the n/a's ecu no longer gives out the right fuel mixture once you have done things like intake and exaust... so since the mixture isnt right its not making max power, so tuning it with an safc would get more power... i think some ppl have seen about 10 or so hp out of it, as well as better gas millage

My buddy had one on his streetported n/a....noticed no difference at all power wise. Just looked pretty...but it was a n/a sooo....

good call.. that seems logical.. still curious if anyone can vouge for it though?

i would still rather save up the extra cash and go microtec though if i was going to go as far as safc..

I want to know more about the Jet Chip. White Seven: you had to have your ecu sent off, and they send it back? How were the gains? Anyone else have comments on the Jet Chip?

They state on their web page: "Non Turbo Cars...Complete Modified fuel and ignition curves from 1600 RPM to WOT and raised rev limits were necessary." ...Looks promising.

I also wonder what this thing could do.

This is the biggest misinformationed thread i think i have ever seen. Jet chips and the like are worthless compaired to an S-AFC. Chips change things one time, and are all the same, and may not be good for your car specifically, but the car they tested it on originally. S-AFC is real time you have control over it, change it everyday if you like, see how far your air flow meter is opening and lots of bells and wistles. Ive heard that a stock N/A FC runs about a 10:1-11:1 A/F ratio at WOT. Thats so ******* rediculously rich its not funny. I would run a turbo car with tons of boost at about that ratio, if not leaner. The N/A and TII FCs can all deffinatly benifit from a fuel controler.

Did he get it professionally tuned on a dyno? How easy would it be to tune it yourself without a dyno?

A microtech is 700$ new. A safc is between 300 and 350 new. Why not just save for another two weeks (or whatever) and get the real deal?

White_Seven

Yes, to me it was worth the $400 and like I said, I will be doing it again once I am satisfied the new T2 conversion is stable and broken in. I can't tell you how much HP the gain was, other than saying it was VERY noticeable.

Yes, I sent the ECU to them and it was sent back really quick (helps that both I and the company are in California). Prior to the chip, my car felt as if it were struggling from 5500 rpm through redline, but after the chip it ran stronger than ever all the way through to redline.



I am sure that an S-AFC is much better than a chip of any sort, but for those that do not want to go through with something like that (or that did not know about it when looking into chips, such as myself) I recommend it. The company specifically asks you what mods you have done to your car so they can better adjust the chip when they install it. Whether or not this is B.S. I do not know. What I do know is that there was a very noticeable difference from before and after with the Jet Chip. And for those interested, I passed smog here in California twice with my chip installed.

safc = 200 dollars now.

FWIW I WILL be going lt8 or e6k as soon as funds permit, but the safc will do until then.

I'd wait on the microtech for NA cars until they come out for one for NA. The current one is for the turbo II's and has limited number of points you can correct for in vacuum, ie, a NA car. But for original post was for an NA, and if that's the case, try a chip since it does change fuel and timing, whereas the SAFC will only do fuel. It might not be the best mixture for your car but if the maps are put together well enough, it should be good enough for most owners who don't want to worry about tuning something they really have no clue about.

my thoughts exactly.. i was looking into getting an safc, but after speaking with a few other owners, i started thinking if i just waited a few extra weeks i could probably get a microtec.. much better results than anything from a microtec.
