NIStune users unite

[jlinder]

Hello all,
I thought it would be useful to start a NIStune thread, where we could help each other out with tunning issues or any other lessons learned. I have been running my NIStune for 10 months now, and love it. I still tinker with the tune now and then, and usually make slight improvements. I know that Zilvia wont let us attach a .bin file, so we will have to send them through email.

I am running a S13 blacktop SR20 with 550cc injectors, N60 maf, and a FP BIG28 turbo. The tune that I wanted to attach works great for me. It idles strong and the air fuel ratio is great at cruising (14.6 - 14.9) and rocks solid under full boost (11.8 AFR) which is 19 lbs. Remember, I do live in Florida so we have 93 octane (sweet). So if you are stuck with 91 octane, you my want to pull the timing down just a hair.

Email me [email protected] for the bin file, I hope this helps someone get started, and I hope this thread will grow.

[Katsumbhong]

I'm planning to run Nistune once funds are plentiful on my '92 240sx stateside. I'll make sure the keep a spare engine on standby in case of noob tuning mistakes.

[jlinder]

You will find NIStune is very easy to use. Let me know if I can help.:coold:

[sillyvia13]

I am still rom tuning... dohc ka...
but soon enough nistune....
I have real time on sohc and rb's tho!
what turbo is it your running?

[UNISA JECS]

I'll help anyone out as much as I can also, I also have a pretty awesome tune for my KA24DET thats works great for me, heres my setup if anyone wants to try out this tune or soomewhere to start from:

KA24DET (9.5:1)
NGK BKR6E .035"
***Stock MAF
S13 T25 @ 7-8psi boost
***370cc @ ~3.8 bar
Q45 fuel pump
91 Octane
WOT AFR's ~11.8's
Cruise AFR's 14.7-14.9
SMIC
3.75" exhaust
***Base timing stock (20*)

Driven this car in 100+ degree weather plenty of time hard and no problems even with the stock SMIC., just hit me up for a copy of the .bin

***If you setup is not exactly like this, especially the 3.8 bar fuel pressure and MAF that this tune was setup around catastrophic events will most likely ensue. In other words if your setup isn't exactly like mines, this tune becomes total garbage to you. I can't stress this enough.

[jlinder]

I am running a BIG28 made by Forced Performance Turbo's. You can check it out at Forced Performance Turbochargers: Nissan SR20 FP Big 28 Upgrade (http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=TUN2528&Category_Code=Nissan-Turbo)
It's a great bolt on turbo, there is no modifications to be made at all, but the Garrett 2871r .64 is in my mind the best for the SR with a stock bottom end.

Maybe the OP should add all the links to the nistune websites so people that dont have it can look it up and figure how to get it for their application, in the first post. IMO

I know what it is, just wanna see more info about it.

[spngr311]

You know I'll be running it! I was impressed when I saw it running.

Here's a link to it:

NIStune - Nissan Realtime ECU tuning (http://www.nistune.com/)

[Katsumbhong]

For the price and the wide range of adjustability, Nistune is a great option for ECU tuning.

[jlinder]

If anybody is interested in NIStune email Pete at PLMS Developments Homepage (http://www.plmsdevelopments.com/) . He was a big help for me. I purchased my NIStune software and hardware through him. spngr311 has seen it in action in my car, and he is going to order his soon.

[slider2828]

Hi Unsia, do you think 11.8 is pretty rich even at WOT? Would that be dependednt on Octane as well?

[UNISA JECS]

Hi Unsia, do you think 11.8 is pretty rich even at WOT? Would that be dependednt on Octane as well?

It just depends on the specific tune in regaurds to how much timing is on the tune, example... if I was running 12.5 AFR @ WOT i'd deffinantly run less timing than I would for 11.8 or 11.5. But to answer your question for my specific setup I feel good with the ~11.8 AFR im running. I think with higher octane you should be able to get away with a leaner AFR @ WOT and more timing but I run 91 octane only, thats the highest octane in my area.

[Yellow4g63]

Nistune here on my RB20 ECU. As soon as the car makes smoke I'm going to the dyno to try out the mods I have.

[slider2828]

Running less timing as in, retard it more? As per instead of 15BDTC like 11 BDTC or something?

And have you seen anything about how read logs to look indicate where timing is needed?

Yes as in more retarded.....no, with my timing im being conservative until I actually buy a Turbo XS knocklite or soemthing along those lines to monitor knock.

Here is some good info from Innovate on AFR's and timing.

You CAN be too Rich :: Application Notes (http://www.innovatemotorsports.com/resources/rich.php)

Spark Timing Myths Debunked - Spark Timing Myths Explained:: Application Notes (http://www.innovatemotorsports.com/resources/myths.php)

[slider2828]

Doesn't the nistune system monitor knock? BUt retarding timing actually gets rid of your knock problem.

Thanks for those two readings, but I read those like about 2 years ago when the LM-1 came out which I own.... I basically retard about 3 - 4 degrees from 5000 - redline...

Its just a little retard, but I tell you, I have 600cc injectors on a GT2871R at 16Psi and I am not even close to maxing out by retarding the timing its great....

While on a Emanage BLue, I wish I could set injector lag tme a ittle. That would be so helpful hahaha...

[UNISA JECS]

Currently only certain ecu monitor knock, forgot which ones do, but there working on it, soon otehr ECU should have that capability from what I been reading on the Nistune forum.

[jlinder]

If anybody needs help:hug:, I do have other SR tunes. Just ask, I may have what you are looking for. I am working on a tune for my buddy, he is running a S13 SR20 blacktop with 740cc injectors, z32 maf, and 2871r .64 turbo. Like I said, these tunes my not be prefect for you, but it may give you a great place to start fine tunning from.

[LA_phantom_240]

Any ideas if NIStune would do any good on a mostly stock KA? lol

[steve shadows]

Unite....and then drive your cars to my dyno! :2f2f:

[jlinder]

Yes, NIStune could do many things for your KA. It can unlock your speed limiter, set your rev limiter to what ever RPM you want, remove some fuel from your top end (bring it up to a 12.0 ARF @ full throttle), modify your timing to squeeze out any untapped power, and go to a better flowing Maf sensor. You could go the other way with NIStune, tune for Maximum Fuel Mileage. NIStune is a great investment for any Nissan owner.

[steve shadows]

The point of the article is that by running a retarded map you produce more energy in the cylinder for finding the peak cylinder pressure. When you retard your timing in a cell you actually cause a leaner burn. Advancing will often result in a richer burn, too far in either direction and you begin to lose power and bog or knock.

The goal is to aim for a more power yielding rpm and adjust timing to produce the most power at that target AFR. This is why you use a dyno.

[slider2828]

Retarded as in less timing advance produces a richer and more timing advance produces a leaner burn....

So at the same fuel level 10BDTC will have a richer AFR

and at 17 BDTC will have a leaner burn

Correct?

[steve shadows]

You have it backwards.

More advanced equals a richer reading at the 02 sensor.

Less advance equals a leaner reading at the 02 sensor.

You cannot however advance under increasing pressure past the point where cylinder pressure is most efficient, then even if the motor is outputing a lean AFR it will be knocking more and more as you advance past the point of optimal pressure.

Hence the point of the article, more advance does not mean more power, in all situations. Set a target AFR for efficiency and then use a dyno to tune for maximum torque/rpm at the best timing. This is why you need to use something that can actually read the output of the engine to tune the timing portion of a car's ecm properly.

[slider2828]

I had a further question, on my emanage, it seems like I record on my wideband, by retarding the timing, it causes a richer afr though...

[UNISA JECS]

More advance give more time for complete combustion to occur for a richer AFR, according to the article AFR's in the range of 12-13 burn quicker than a mixture leaner or richer than this 12-13 range.

So if you run your AFR's richer than 12.1 you would want to run more timing advance for the slower burning mixture to ignite as much as possible and if you run between 12-13 AFRs you need less timing becasue this mixture range produces the most complete combustion in a shorter amount of time. Running to much advance with the later should produce detonation becasue combustion would complete to quickly and not at the optimal point, what is it like 15 degree ATDC when combustion ideally shoudl be complete? This is what I gathered form that article atleast...

[slider2828]

Yah that is what I gathered. So if I ran at 17 BTDC, then compared to 15 BDTC, it will cause a more complete burn therefore it SHOULD make it leaner without messing up other stuff.

and vice versa, that is what I get from the article as well...

[mifesto]

says later s14 models are not compatible :(

[spngr311]

Email them about that. They were working on it when I emailed them a few weeks ago.

[Xylemer]

I am running Nistune on my S14 with a a KA-T... I have messed with standard daughter boards and bikirom megaboards, and Nistune by far, is the best I have used.
It is very user friendly, and works with very little problems... the guys a Nistune know what they are doing... and I only anticipate it will get more popular and more expensive... it is as close as you can get to a stand-alone, with out the price.
I really cant say anything bad, except Nistune is still young and will only get better... It may not work with every ecu, but give it some time, new features and ecus are added often.
I too will help answer questions about Nistune, PM me.

[ManoNegra]

Friend has it
I plan on getting it eventually
biggest plus for me is that I can tune my KA for daily duty
and still be smog legal
and, when I decide to, I can got KA-T
or switch between the two just by changing
bolt-ons and swapping bins

as far as being young, I don't know, my friend has
had his Nistune for about 3 years now
got it directly from Australia
and it's actually gotten cheaper now that there
are US authorized dealers

You can order from Pete at PLMS Realtime Tuning (http://www.plmsdevelopments.com/realtime.shtml) also.

[Silverstreek]

so, wait if i have questions about nistune itself and not necessarily how to tune with it, this would be the wrong thread? cause i have a few questions that aren't related to tuning with nistune, but just with it in general (i.e. like when i send my pcm, they pull the chip out, socket it, put a programmable chip in and then do they put the factory nissan program on the chip so you can go from there or do you get it back with nothing and you're on your own starting from scratch or what?).
i understand pretty much everything else.

Basically you just will have an "unlocked" ECU and it will still retain the stock .bin program in it and drive just like stock until you decide to tune it.

[NismoFreak]

Yeah i too have been wondering this. with my last car...91 talon TSI, i had AEM EMS and hated that thing to start with! thank god i have a friend that is a master AEM EMS tuner!

I dont know how to tune, iam reading a lot and trying my best to learn. so would this be a good set up for a novice?

right on, that's what i needed to know, thanks!

[koukimonstersr20]

Hi there, im new to this forum, im from South Africa!!, Im currently the only one here that runs nistune in my s14 sr20det , I need some help do you have bin files for me?? I will tell you about the modifications roughly.
Seems you are a guy that knows what is going on !! or ?? any other help appreciated!!

[xs240]

i cant wait to get mine. I'm hoping to get somewhere between 150 to 180 whp with all the ka boltons i've got. Broad range sure, but I am hopeful :) We need more KA NA resources...

[hottscennessey]

I might eventually go this route

Anyone using Tunerpro RT with a Calum RT ECU? How does it compare?

[smelly240]

There are a few people in south africa with primeras with nistune.

Tunerpro is good but is garbage in comparison

I do prefer working with calums hardware with nistunes software tho.

Calums software works like a eprom emulator - meaning you can upload to it whatever code you want... all the patches for antilag/launch, elec fan control, leanburn. With Nistune you have to have the base image changed with whatever matt releases, because it works like dsmlink/ecmlink where it just has a base image that u can edit parameters on.

Nistunes software works with dual ostrich setups, calumRT, romulators, and u can simply burn chips with it too. It is fantastic and supports most widebands, and you can add other sensors with a 5v very easily. Add lookup table, and go.

can u elaborate on the calum with nistune software deal? It's a better way to go? More features?

[UNISA JECS]

All said and done Nistune is the better route to go IMO, ofcourse if you know how to add registrys and like to tweak around more then you probably would go for the calum setup, but if your here asking any questions about which route to go then you most likely will not be using the calum to its one advantage, just wait becasue Nistune will also add the cool and new registrys calum and his users find for you in a software update.

Plus if you use Innovate wideband you can log AFR, Boost, Vacuum, Oil Temp, Air intake Temp, Fuel Pressure and more within Nistune all on the same datalog along with all consult registrys already there :).

[bradystrib]

i just ordered nistune. A shop in North Carolina is now an official nistune dealer. Going to be tuning a KA-T with z32 maf, 550ccs, 2871r .84...

[murda-c]

I want launch control.

[s14unimog]

I'm running Nistune on my s13SR. I love the system b/c you can monitor consult data right from the display. The interface, as intimidating as it looked in the beginning, is actually really easy to use. I love when I have a faulty sensor too, I can view all of the voltage outputs to trouble shoot faulty sensors.

here is a screen shot from my car. Consult connected...
http://img.photobucket.com/albums/v721/s14unimog/DSC00502.jpg

[smelly240]

with the calum board you can run any file you want... with the nistune board you cannot edit the code... only the parameters of the basefile that is on it.

say u want launch control (not offered by nistune natively yet) you'll have to wait until matt implements it into the ent file - that gets flashed onto your board.

you can edit maps...

i been putting vss triggered launch on s13 SR's ;) obee loves it.

im really interested in getting one of these in the next month but i have some questions. not sure if this is a good place to post em but ill give it a shot. I have and auto to manual trans swap and im running an auto ecu will this make a difference? Does the $400 price tag include them soldering it in? thanks for the help i really want one

hello!

a friend of me has bought the nistune for the RNN14 GTIR. after i have take a look into the software and i just wondering becausetherei don´t can see an boost settings table?? where must adjust them??

What is everyone doing about the emulator issues?

If you're just data logging and doing pulls on a roller dyno I'm sure it's fine but I hate this thing for Real Time tuning on steady state dynos because you have to use a freaking emulator, I prefer to write to the actual EMS in realtime so I can watch torque in steady state

Also beware of posts from people with 5-10 posts total going off on how amazing any particular product is.

I have seen people who love their Nist-Tunes and people who threw them in the f*cking trash a few weeks after they bought them and went with a standalone

It definitely has it's merits in the marketplace.

[Yellow4g63]

Ummm you write to it real time once you connect to it with the laptop. when you are done you save the changes to your laptop unless you want to retrieve it from the computer and not load it from the laptop.

Thats what I was gonna say to.

[handinpants]

Curious steve, were any of the people who threw them in the trash your customers? Just wondering... cause I haven't heard about that. As far as your emulator issue contact matt directly at nistune.

I have nistune, and it was installed and tuned by chris at dc performance. While dc performance is pretty pricey with its exotic car tuning, chris' prices are severly cheap and reasonable, for a exotic care tuning shop

[GroundPerformance]

LOL.. Running MAF based standalone is throwing your money in the trash. So let say it's a bit challenging to tune which I seriously doubt. What it all comes down to is that the job gets done the and for less. Period......

[UNISA JECS]

You can do what I do with my nistune, I add a MAP sensor threw one of my aux channels on my Innovate LM-2 wideband which allows me to log my MAP values, vacumm and pressure along with everything consult logs all on the same screen at the same time, takes the guess work out the equation.

[s14unimog]

Is anyone running a Zeitronix with their Nistune system? I can't seem to get the EGT's to match...

I do wish I could log more than 4 inputs tho...Or maybe I'm missing something.

[Yellow4g63]

I have a Zeitronix's but I didn't log my egt last time I had my car on the dyno :(. Might be the settings in the nistune software.

[s14unimog]

Yeah I've been looking but the window that pops up for the Zeitronix doesn't seem to have any options. I went through "configurations" and have it set to imperial units but I think that only effects the coolant readings from the OEM sensor. I'll look around on Nistune's forum.

I have a quick question, do you have to have Nistune to view the logs? I was thinking it would be so clutch if I could log some pulls and send them to my tuner for review.

[Yellow4g63]

You can use log works to view them. The info is on the nistune forum how to do it. Let Matt know about the EGT and should be able to make the changes to the software if that's the problem.

[s14unimog]

okay cool, thanks for the information on logging. I just made a thread on the boards; I couldn't find anyone else with this symptom.

[hexdmy]

Steve, why do you have to pollute forums with this stuff. You know that Nistune is tunable in real time, yet you continue to confuse people by throwing out these nonsense statements / questions. Please stop, you are only making yourself look ignorant .

I would love to see one person stupid enough to throw it away.. Plenty of people are using Nistune and such to make just as much power as a standalone.. If your goals can be met with a MAF sensor then save money and get a Nistune...

^^ thanks for the vid bro that's my car above being tuned by Chris at DC Performance. I have nothing but good things to say about nistune which was tuned in real time my car feels great and my obd2 scanner still works so i could read engine codes. Chris is an awesome experienced tuner, i think he spent over 12 hours on my car alone in the two days i went because of faulty sensors that gave us problems on the first day. He is a great guy and wont let his customers leave unhappy no matter if its a high end exotic car or a daily 240sx like mine i would tell anyone in socal that's thinking about nistune to head over to Chris at DC performance his prices are very reasonable for the amount of time he puts into making sure its a safe and reliable tune.
