After i installed a Z32 into my S2 Stagea i decided to make up this little diagram for anyone else looking at the upgrade. This may also be the same as the S1 as i'm sure the AFM's are basically the same pink label MAF. The S2 wiring was almost identical to the S2 R33 wiring with the exception of cable colour. Also keep in mind you cant install a Z32 and run the engine without a tune.

how much has all this cost you.

what will u gain? power and fuel maybe?? running an safc to tune it?

You can get a brand new Z32 for around $300. Then either shell out for a Tomei Z32 plug like I did, or use a VL AFM plug, I read they are the same.

There is no real gain to be had unless your chasing anything above 220kw. And then it's more of a must to chase the bigger power figure. The Z32 has more resolution than the stock AFM.

I'm using Nistune to tune for the Z32, but you can use a Safc.

No gain unless he's got a bigger turbo and his stock afm is on max voltage.

Stock afm's can only read up to a certain amount of airflow while the z32's can read more. Its just a supportive mod for bigger power really

Hey thanks Josh, looking to do this on my S2 soon and you just took all the hard work out!

Dave, installing a Z32 pretty much renders you car undriveable until you get a tune. Your running Nistune as well aren't you? its relatively easy to setup but from my experience from just doing this, its not as easy as changing the VQ map to suit the Z32. For me the fuel mixtures where off and needed to be adjusted.

Thanks for the info - yes I'm running a Nistune as well; I just picked up a Z32 and so came back to this thread :) I was told it's a Tomei plug but the colours are different to yours. I will be getting a full tune when I install.

strange, although it is highly possible that tomei have just used different colour cables. just match up the pin id letters and you'll be fine. if your doing the install yourself make sure you can still get you car to the tuners as you wont be able to safely start and drive your car. what you could do is wire in the Z32 plug in parallel with the stock one, that way you can drive to the tuners on the stock AFM, then all the tuner has to do is swap the AFM and tune away.

      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!
