I currently use it on my ka piggy-backing my JWT ECU. However, I did not install it. So the first answer is, yes, it works. However, I'm at a level of tune that I will be upgrading to Nistune or some other more complete tuning system. It has its limitations, but you may be alright for a basic turbo. Sorry I can't help more- might want to check the KA-T forums.

Hey man, i have a brand new in the box plug and play harness for an AFC Neo. I bought it when i bought my AFC a year or so ago but ended up having to ditch everything since i decided to swap. Let me know if you would like it because its just been sitting in my house doing nothing and i spent $180 on it. We can make a good deal if you want. It is a super easy really clean install.

Congratulations on the deal on that Neo, that is CHEAP

IDK about NEO but that it's just the same thing as the SAFC II with a VSAFC built into it so it works for hondas and all others cars... So I'd say on a Nissan it should compair to my SAFC II perfectly.... It's a useful tool... but one thing to note.. YOUR ALWAYS FIGHTING THE ECU. If you lean it out, the ECU will read that the car is lean from the 02 sensor, then add fuel. IF you add fuel the ECU will read that you are rich from the ECU and will lean itself back out. This will happen any time the car is running within the limits of the O2 sensor. And why you need a wideband O2 sensor to run a fuel controller properly. Where it really helps is if your car isn't running properly and you cant figure out why... you can pretty much override any a/f problem with this thing. Cause if it's not running right that means the ECU can't adjust itself enough and needs help. The 02 sensor (being as it is a narrowband and all) can only adjust the A/F ratio so much.

But, if you have a z32 MAF or some other mix combination this is EXACTLY what you need.

What I use mine for mostly is a diagnostic tool. You can affect the power and fuel mileage to a small degree with an otherwise stock engine/etc but if you go anymore than ~5% with it the ECU just adjusts and totally negates all your changes...

And as for install... for a KA it's kinda hard to figure out the right wires because Apexi doesn't provide a diagram for these engines... only sr's and rb's. But using the FSM it's easy to figure out. I installed mine and my friends in under 30 min each. And average joe wise... it's pretty simple to use if you read the instructions THOUROUGHLY. If you don't have the instructions then you can d/l the PDF at apexi's website. Fairly simple once you understand what it all is and what it all means and does.

I hate messing with the factory harness, why chop it up if someone makes a plug and play harness?

No kidding... I wish I had one for mine... But seing as mines SAFC-II I don't think your harness will work with my unit...

[OM3GA]

Yeah, not sure if it would. I know they make one for that unit too.
