Capacity Of Nistune

[Simon-S14]

yeah that usually is a fault of the sensors. I know with my SR which i had a PFC on it when i revved it it told me i had knock over 150.. even on free rev with no load. pulling 5 deg timing out of the map didnt change it so had to be a f**ked sensor.

the system is only as good as the componants on board

I actually prefer the readout and warning light in a way.

Atleast u know to back off and check it out, check temps etc.

I do like and tune alot of nistune's im just not 100% certain of how well they detect knock and switch to the knock maps.

I still set the knockmaps up.

One thing to not is the stock knock sensing on the timin maps is normally only on a small percentage of the map and i have never seen the area flagged on the map go near or above max torque, i suspect the knock sensing gets confused with valvetrain noise

I am just new to skylines...bought a R34 GTS-T recently with no such modification with engine or any performance enhancements

can anybody let me know what difference Nistune will gonna make on the performance of the car & how does the intercooler kit helps in that as well.

Hello,

Without any mods the added benefit of Nistune would be only the delimited top speed

If you don't plan on modifying your car a great deal then I would stick to the genuine ECU.

nistune puts a daughterboard inside the genuine ECU. Stock maps with an exhaust and intercooler cause it to run really rich, there is a rather large gain going to a nistune (or PFC etc)

[Torques]

Sorry if this has been covered before, but are you able to have multiple tunes (eg: economical tune & performance tune) with NIStune and be able to swap tunes with a computer?

EDIT: nvm, I found my answers, cheers

You can have as many maps as your laptop can hold, but Nistune knows just about one set of 'maps'

theres gains to be had with retuning the car.. nistune just allows you to alter the overly rich nissan maps.

Extra 10-15 rwkw on a (stock but exhausted+intercooled+14psi) RB20DET with just the mixtures fixed up. A little more with braver timing.

Spot on mate!

(I doubt the extra 30KW stated here ...)

[Torques]

True - but the cost of Nistune and the tune is not worth a gain of 10-13KW, is it?

I guess it all depends on your plans with your car.

I have Nistune and I like it.

But when I swapped Nistune for the standard ECU and had the car tuned I was quite unhappy.

I expected a huge power gain, but all I got was 12KW more

(That running the standard turbo at 12PSI)

If the car is hitting R&R massively you will get like 110-120rwkw max with the stock ecu, with intercooler, boost to 12psi, exhaust etc you will see 150-170kw, I personally saw an increase from 109rwkw to 151rwkw with my redtop with JUST a tune, nothing else. If your car is well sorted and it for some lucky reason doesn't hit the R&R part of the map it will not be as much of a difference.

EIther way if you do ANY other mods like upgraded turbo you need a nistune or aftermarket ECU. Basically it is one of the necessary steps for any other mods so it is totally worth doing.

My NIStune is probably the second favourite mod I have done to the car so far. Fair enough I had done all the usual mods before I got it, but Its not just about power, the power figure is just a number. It completed changed the way the car drove, improved fuel economy by an amazing amount, etc. It was bucket loads more fun after the tune.

And for what, less than 1k? Not expensive in the slightest compared to other mods I have done that made less noticeable difference.

[The Dan]

V500 is junk... cannot be compared to a $1400 LINK G4 or Vipec or haltech for that matter... worlds apart in quality.

hahahahahaa. That is pretty funny.

Please explain why it is junk

[Torques]

True, as I said it depends on what plans you have with your car.

However, I was lucky enough to get about 310HP ('at the clutch') at about 10-11PSI, standard exhaust, standard intake, standard ECU.

This was as good as it got, since from there all further mods required a 're-tune' or/and new ECU.

(So I agree 100% with what you write ..)

Any one wanna share their popcorn with me. I like forum debates

[Rolls]

I'm genuinely curious in both sides.

[DVS JEZ]

Every one has there own opinion and likes different things.

[Rolls]

Some software and hardware genuinely is better though, it is just hard to find out what is.

i tune everything and anything and dont "deal" any particular product so im not biased in any direction, i take each ecu based on its merits and out of all the brands there are there is only ONE i no longer touch and that is wolf.... for more reasons than i can post here.... timing drift being one of the prominent ones.

I'm sure you are right.

that may be the reason the EFI boys run 150mph on standard engines. Who knows

[Guilt-Toy]

The ECU is just as good as its tuner.

I could make a $700 haltech drive better then a stock ecu, control the VCT and have boost control. Even when using them on big turbo setup's.

Forget what everyone says about ECU's and start worrying what they say about tuners, find a good one and you won't have any problems.

My opinion on Nistune is that it is great for any nissan where their setup does not suffer using a MAF, there is no real reason to go for anything else unless you have additional requirements, some ecu's can have a flex sensor and trim the map depending on how much eth content, you can even fill half the tank with e85 and half with 98 and have no worries about you're tune without having to do anything.

My friend here (another tuner) did a test on a 2jz supra with a T51r, he had it running on full sequential then ran the car on 2 injector outputs. There was 0 difference in the tune, drives the same and power is the same so he gave the car to the customer running on 2 injector outputs.

So really its not allways about the hardware you are using but how much confidence the tuner has because the technology these ecu's have these days are amazing it just takes someone to know his shit to put it to good use.
