Are the S-SAFC2 easy to tune and will I get much of a power increase? Need one for a ca18det. All thats on the car is intercooler, turbo back exhaust. Just didnt know if I will need after market injectors, fuel pump, etc. Still want the car to be reliable but want more power and I know the CA's are good for quite a bit of power.They are piggy back are they easy to install? Im from Tassie any help or ideas would be awsome.

THANX

Tonight I just had my R33 GTST dyno tuned by Unigroup. Mods were turboback exhaust, k&n panel, apexi safc2 and avcr. The results surprised me quite a bit given the relatively 'stockish' mods, but im more happy that the safc tune managed to smooth out an irratic power curve ...

The dyno tune took about an hour and costed me $200 for safc/avcr/base timing, I'm quite happy with it...

shoey,

What was causing the big drop in power over 5000rpm? I have the same type of mods as you and my car is suffering from the same problem, so I am looking at getting an SAFC fitted soon. Was it running too rich or was it a problem with detonation?

Cheers

Simon.

Simon,

What Yavuz (the tuner) explained to me was, under the boost curve for the 'standard' setup (ie the avcr was setted to self learn 10psi, with no rpm specific learning, etc), the avcr started building up to 10psi at the 6k rpm mark very sharply, so the ecu backed off, as a result the boost dropped off a bit and the ecu let power pick up again.

they're easy to install, just take it slowly and be sure to run through the config BEFORE starting :D I have a near stock engine (pod and std exhaust at the time) with a bigger pump, and when I had mine tuned i saw ~20rwkw more, but obviously that varies between cars :D mine was running waaaayy too rich because of the pump, so the safc did the trick :D

I recently put an SAFC into my girlfriend's 180 (w/ CA18DET) and was none too difficult.

Good luck :)

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
