Power Fc Vs Nistune

[Rolls]

Its not a serious question, Its a trick question. Its also a demonstration to show that statements like the above shouldn't be posted unless you know exactly what you are talking about.

So why do you "know exactly what you are talking about" and others don't ?

So why do you "know exactly what you are talking about" and others don't ?

Anything I post, I make sure I know what I am saying and have some sort of real world relevance as an example.

I don't just bust out comments like "More revs means more inefficiencies due to friction in all the moving parts"

All the parts weigh the same, with more revs they are doing the same work more often. Does this make them or the engine less efficient?

Now I don't know the answer. But do I post it unless I do know the answer. No

So valve bounce is part of my imagination?

lol wtf happened to this thread???

and what does BMSP have to do with anything realting to the tuneability of an ECU

Because he is a very experienced tuner, and you are not?

What does tuning have to do with me saying two engines making the same power level will use different amounts of fuel? He even agreed they would use different amounts of fuel, I don't even know why there is a debate.

If we really want to make appeals to authority to justify our claims, then I am the engineer and he is not. Kind of silly isn't it?

lol I think the OP came to a conclusion ages ago.

He probably sold his car after reading all this haha

A street turbo that comes on @ 4500rpm - when you don't go over 5000rpm?

500rpm band... awesome.

Quote of the week .. i wish i had a 500rpm band of pure awesome .

Hi,

Just to mention:

The Z32 ECU does also switch VTC (or VCT) based on engine load / speed / temperature so a switch based one sole RPM might not be as good.

.

Z32 can control the VCT and it has something else that it can control better, I can't remember but pete from nistune was telling me, might have been something with the knock sensors I can't remember.

But you can easily control the VCT via an MSD window switch or an eboost street (with built in window switch). There is plenty of discussion on the nistune forums and on here regarding the differences if you do a search though.

I've heard of people wiring it permanently on because it performs better than off, so I wouldn't be too worried about it say burning out the solenoid or anything.

Know it is fine in my car using a window switch, I just make it turn off below 1.5k so it isn't on all the time.

[Torques]

Having it on constantly would cost you power at higher RPM.

The genuine R33 ECU switches off at around 4600RPM.

I guess a window switch will work fine, though the load triggered activation has a certain appeal to it.

Its mainly people with rb20 ecu's or ones that that dont have any control over the vtc. NIStune have proved

That running the vtc permantly on is alot better for mid to low power/torque but may lose 10 kw at peak power

[Torques]

Still one has to ask himself why did Nissan go through all the hassle of VTC activation if switching it on permanently

just takes off 10KW at the upper band.

(So I don't buy the 10KW)

I think some people don't understand what VCT is actually doing..

There are comparison dyno graphs somewhere on here, I know mine added 15kw in the midrange, unsure of top end loss with it stuck on though.

When trying to sell cars the 10kw is a massive thing.

Just like those guys running 290ish kw's that 10kw puts them in the 300's which is huuge just because it has a 3 at the start of it

[Don Dada]

Mine lost a shit load more than 10kw and also misfired with it on in the upper revs.

I believe i posted a graph some where around....Cant find it right now tho

[DVS JEZ]

I will try it with my drift car.

Were also trying another cheap vtc setup which is always on but the turns off above a preset rpm say 5000rpm. This works out alot cheaper and should do exactly what we want

[Manuel Kasko]

We can easily test this with my car as I will have the Window Switch.

So you can play around with what RPM it turns on and off at.
