Figured some of you might need it.
SAFC II
Red - power
Green - rpm signal
Gray - Throttle signal (TPS)
Brown - Ground
Black - Ground
Yellow - A/F Output (this goes towards the ECU)
White - A/F Input (goes away from ECU)
Blue is not used on Nissan Z33 that I know of. Can anyone confirm this?
Pink Not used (Used on Karman vehicles)
Orange Not used (Used on Karman vehicles)
Purple - Knock
I was told Karman is for vehicles like VW.

If anyone needs an S-AFC II or S-AFC limited Edition I have them all in stock.

What is the price for S-afc II Limited edition?

Omega350Z

Why not just post your prices here on the forum? Are you just pricing these units on a per customer basis? Ive seen the regular blue S-AFC2 unit selling for as low as 290 dollars plus like 8 dollars UPS shipping, can you beat that price (NO, this was not on ebay, they are averaging around 310 plus an outrageous 20 dollars shipping)? Other than the limited supply of the white light/black faced S-AFC2 what would be a benefit to buying this item, and why would you charge more for it if it is the same electronics inside the casing? Also, do you have wiring harnesses available so we could just plug it in and go, or are we still stuck splicing wires ourself?

Correct me if I'm wrong- but back when I was tuning my Venge, People were using the Super AFC mostly for turbos. What is the benefit of using the SAFC in a NA engine?? I really don't know, can someone explain it to me?? I thought it was for teaching the computer new fuel maps or something, or optimizing the air/fuel ratio.... but how would this benefit NA cars. Wont' the computer override the new maps or not work corretly? I thought I remembered hearing that. I dunno. Any info most welcome!

I don't like posting pricing on a forum as this forum is for information and to help people with technical questions. As for wiring harnesses no, no one makes one for the 350Z. I make one for the WRX but that's all. It's very expensive though. Almost the price of the unit. Just splice your wiring. Solder the connections and you'll be just fine. Rizzness, the S-AFC will help by giving you the ability to tune your fuel curve. These cars run pig rich stock (or even modded) and by taking fuel out at certain points you can increase HP and torque significantly. I usually see at least 10 hp increase at the wheels on any car using S-AFC. Plus you can tune for your mods and get it dialed in perfectly. It's safe. You can add more fuel at certain RPM points as well if your fuel curve becomes too lean. The ECU will not override the maps no. You can tune part throttle and full throttle. Full throttle mapping is what you probably want to tune sicne part throttle the ECU does a fine job.

Like Guru stated, playing the the A/F ratios on this unit really do help your powercurve, and your fuel economy as well. However, you need to spend some time on the dyno and have it tuned there so that you can set your level such that you maintain a stoicmetric A/F ratio.

IF you know what you're doing...

The AFC utilizes the oem narrowband o2 sensors, which aren't worth crap anyway. The ONLY way to harness this thing, is to (A) get someone that knows fuel curves and to slap a wideband on it while on a dyno. Get them to study what is EXACTLY going on... THEN dial in numbers in a controlled environment.

Just plugging it and... then screwing around will ONLY result in a blown motor.

Trust me... its happened.

Though on the flip slide... if they are tuned right, they can do AMAZING things!

Thanks guys:
All of the above now sounds familliar again. It makes sense too. I do remember hearing that good gains and fuel economy can be achieved, but considerable tuning and multiple dyno tests are necessary. Thanks for the info!!!
