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 :)

      R34 Skyline climate control unit transistor

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
