Power Fc Vs Nistune

[Rolls]

A safer way to tune is to make a intake temp ignition/fuel trim table, and another one for coolant temp.

That way if you do stupid stuff like do a burnout in summer you wont cook the motor.

[GTSBoy]

Yeah, but as I've told you before, they don't have these tables in Nissan ECUs. Only the RB26 even has an inlet air temp sensor. The whole point of my post was that you have to work with what you've got. In the case of Nistune, it means that the knock maps are not always reliable, so you have to decide if you're going to try to live with random changes of map (when it shouldn't), or it never changing because it never detects knock even when it happens (which also occurs, and is of course worse) or whether you're going to disable it and tune sensibly to avoid the problem altogether. It is possible to tune so that you might miss out on some winter performance, but you won't ping it to death in summer.

Burnouts are dumb at the best of times. So I say that motors that cook as a result are not a problem, just an education.

Random changes....sounds a bit disconcerting for a daily driven car.

If I do go for a nistune/PFC the closest tuner will be nearly 2 hours away, which makes me think any drama's will be a big hassle for me.

nistune has coolant temp trim tables.

but yeah do what you said re just tuning for summer and itll be fine all year

There's no reason to be stressed about it. Once tuned, a nistuned ECU should be able to be left alone until you change something on the engine. Mine hasn't been hooked back up to the laptop since it was tuned years ago (apart from just to have a look at something.)

ok, cool. Well I am pretty much sold on the nistune, seems to be the best bang for buck option. And it seems they don't make PowerFC's anymore (not that it really matters).

What is the going rate for a nistune....tune?

[DVS JEZ]

Depends which State. Some sydney guys charge $1350 + z32 ecu,

Im cheaper

[Rolls]

nistune have raised the price to 400 for an ecu, so usually close to $1k tuned and installed, sometimes more. If its stock engine it is easy to tune so usually a lot cheaper than if you have injectors + turbo etc.

[sonnyQ]

guess i'll have to trawl through the QLD site to find some reputable tuners who are nistune friendly. Do I NEED a z32 or is just optional/better than the stock AFM?

And final question (I hope) - I have come across a 2nd hand ecu with nistune already installed, if I were to buy this would it be a simple plug and play and then getting it tuned to my mods?

Thanks again, you guys have been very helpful

[Rolls]

It has a resolution suited to higher airflow, so if you max out the stock one (~240kw ish) then you need a Z32 or it makes tuning very difficult.

Re the ECU no it isn't that simple, you cant just plug an R32 ECU into an R33, you need to wire it in.

So my stock AFM should be fine for the ~200 mark? The ecu/nistune i'm looking at is out of an R34....

EFI do Nistune in QLD and the tuner sean is great, I had my R32 Nistuned by them it never missed a beat as long as I owned it.

I went a Power FC in my R34 GT-T and it's working great, I have had it installed since the car had it's first mods fitted, No issues with the unit what so ever.

If you don't know how to wire in an ECU you are best to just pay someone to do it all for you, probably end up cheaper.

[RandomHero83]

If it is an R33 as far as I know you can only run an R32 ECU or a Z32 one depending on if you want VCT functionality.

[Rolls]

You can run R34 but it means rewiring a lot of stuff for not a huge gain.

Rolls , what makes u think u have to wire in an r32 ecu to a 33?

Aren't some of the sensors different? I had to rewire my CAS plug though I think that is only a neo thing.

If not then that is even more win!

[Hadouken]

This might help the 33 guys wishing to use a 32 ecu.

[DVS JEZ]

Rolls only the VTC needs to be wired in on gtst's. But if u buy a programmed r32 ecu that has rb20 image u will have to either change the tps to a rb20 tps or send the board to NIStune to get a rb25 base image programmed.

On GTR as EAT ME posted, change a few settings in NIStune

[Rolls]

That is right, I had to use a S1 rb25det TPS as the S2 one didn't work with the R32 ecu.

So yeah you have to "wire in" a few things, not very difficult though, but if you aren't electrically useful then you would need to pay someone to do it.
