Z32 Nistune Vs R32 Nistune

[Manuel Kasko]

Hey guys,

So I have been tossing up between the 2.

Right now I am stuck and have read as much as I can up about both options. (yes I used search)

So VCT can be controller for the R32 ECU easily via a window switch ($200 delivered)

Z32 ECU has to be modified to plug into the harness.

Which would you prefer and have you had any bad experiences?

Right now I have lined up a R32 ECU for $100 delivered

Let me know what you would do and which you prefer and why.

Thanks,

Kasko

Both are plug and play once the nistune board is installed. U domt modify the harness u modify the internals if the z32

[Manuel Kasko]

Any opinion on which to choose.

I could of people said the R32 has less issues

I bought a z32 board just have to get it modded and tuned. Asked the tuner about r32 and getting vct to work with it basically a flat out no, dosent work like that. I want the vct so I went with z32

There's a thread about using 8 vs 16 bit Z32 ECUs in R33's. Cant remember the details but IIRC you can tell them apart using the part number and you need to use the 8bit one.

Maybe this was it from the Hypergear thread: LINKY

Thanks mate,

Had a bit of a read through it all

Even looked at their ECU awhile back.

Think I will just stick with the R32 ECU and just get a Window Switch to controller the VCT.

Wish I read the article explaining how one of those Electronic boost controllers has a VCT switch in it.

I just purchased a Greddy Profec 2 for $379

I may say something unusual here, but I think your choice should not be based solely on availability of either ECU. Are you familiar with electronics, programming and anything like that? Do you like to fiddle with parts and set things up yourself or prefer the work to be done for you by a tuner/workshop?

If you're DIY-minded guy, I'd say you should pick Z32 ECU, 'cause it's been around and been played with for a very long time, is much better investigated, and with some work and research you can add different features to it. If you prefer driving your car more then playing with stuff, then you're better off with R32 one.

I have heard of some minor issues in a few cases with the Z32, from what I read it was only a small subset of them, the 16bit ones and possibly some of the 8 bit ones, I would ask the nistune guys to clarify though.

Knowing that the Z32 controls VCT is a fairly big bonus, however if you need a boost controller and buy an Eboost street or Eboost 2 then that has a window switch built in and can control VCT for you, making it free.

i got a z32 one from a jap wreckers sent it to matt (nistune) and plugged and play

Wiring two knock sensors to the single Z32 input seems to be the cause of issues. So either stubbing out with a 470K ohm resistor (ie no knock sensing) or only using a single knock sensor seems to be the preferred option

On the 16 bit Z32 ECU on my bench it was triggering knock maps (with an SR20 sensor which matches the Z32 ECU) having both connected in so would be having a similar effect on 8 bit ECUs. Sam (dr_drift) was the first one to report these type of issues some time ago. We stay away from the 16 bit all together since it has not been tested and the mapping is different (separate fuel and VE maps not as easy to transfer R33 maps onto)

Z32 ECU availability is another issue with the prices on ebay etc increasing due to their increased usefulness on R33s. Ordered a bunch from one of our workshops in the USA so have some here for modifying but they are starting to increase in price there also
