The ECU is always looking at some particular cell depending on load factor/RPM. For me, it was impossible to find one K-value that matched everywhere. 155 was good for low loads, but lean in high loads. 175 was good for high loads, but too rich in low loads. 165 was my compromise value, and I make adjustments in the few cells that need it to reach the AFR I want at that load factor/RPM/pressure level. The Documentation section of the Nistune website has some guides you will want to look at.
Two more features I would like to mention are 1)you can use differently scaled lattices for timing and fuel maps (and other maps also, like boost control or VE map) and 2)the step in lattice does not have to be uniform. I mean - you can increase resolution in transition area by decreasing it around idle or at low loads.
If you increase the K-value, it'll enrichen the whole table, but latency affects the AFR more near idle. If you lower AFR in individual cells on the fuel table, you're adding more fuel. You want a K-value that will make the AFR's on your gauge match the AFR's throughout the fuel table. Once you have that then you can change individual cells to fine-tune particular load factors (lean out highway cruise areas, richen up WOT areas further, etc)
Hey there... I got my Nistune socket ROM in the mail today. I got it installed and was able to connect to my laptop. Its awesome! I am still waiting for the LC-1 to arrive and also the t3/t4 from CherryTurbos. The motor is still out on the stand, I just finished rebuilding it, its ready to go in! Anyways, good job on the vid. Keep me update on your progress. I should be up and running in about 2-3 weeks... can't wait!
This is awesome, we need more videos like these. I want to use this one an S13 with a KA24DE NA with all possible boltons and race clutch and flywheel, 1piece alum driveshaft... it would really help :)
I wrote "used car parts" on the customs paperwork, outbound to australia, and I think there were little to no tax. Coming back to the US, there were no import taxes at all.
Some sort of wideband is critically important, whether you're on the dyno or on the street doing it yourself. Without the wideband sensor you can't tell that your air/fuel ratio is, and therefore cannot see what effect your tuning changes are having.
You change the K constant first according to the size of your injectors, until your idle ratios are where you want. Then you investigate changing individual cells in the fuel map according to when your boost comes on, such as if you installed a bigger turbo. The stock fuel maps wont work in that case
I love living in Australia, have my S15 autech 350rwhp daily and my 450rbhp s13 track weapon :) Just Australian laws on modifications are messed up. Very good video buddy!
Thank yoU SO MUCH FOR THIS VIDEO!! I HAVE A '88 300zx shiro and i need to get it RE tuned since it has a very old tune on it. Thank you again for this video!
Dude this is a great video. My questions have been answered about using this program and I'm gonna make sure to pick this up along with a wideband for this year. What wideband setup are you using?
I sent mine to australia since I wasn't comfortable doing the work myself. They test it and everything you get back a complete ECU ready to go right back into your car. But that was with the Z31 ecu, I'm not familiar with the Z32 ECU's, it may be harder or easier to install Nistune on those. Email the nistune people and they will tell you everything that is necessary
Hey, nice video! The only correction I want to make is that you cannot "add" more and more columns to either load or rev scale but rather you can assign bigger values, stretching rev or load range. The tradeoff here is the resolution of the map - it remains 16x16 cells. I use 550 rpm step instead of factory 400rpm, this gives me 8800rpm reference point at the last row.
The Z32 MAF plugs right into the Z31 harness. Apparently the Z31 MAF has an offset in the voltage that Nistune can remove, allowing the Z31 MAF to meter as much air as the Z32 MAF. I have not tried this myself but that other guy is running around 400RWHP with the Z31 MAF and Nistune. He thinks he can reach 450 before the meter is maxed out.
Great video and explanation of Nistune. I've been thinking about going Nistune for months now. Question is for those of us who currently has a romtune like enthalpy or emance. All we would need to do is desolder the old chip and solder on the nistune daughterboard and we're able to start tuning right?
That explained a lot man, awesome video. maybe this is a stupid question, but is the z32 maf plug and play or is rewiring required? I also have nistune, its hard to figure out how to change the constants not really knowing my afr ratios. First I got to get a new exhaust then install my lc1.
We have a 1993 Nissan 240SX with an RB25DET engine with a Z32 ECU and a NISTune daughter chip Type 1. We need a base tune to get it running so we can drive it to professional tuner with a dyno, etc. Anyone know how we could do this?
Go to the Nistune website, under the software downloads section there are several ROM packs. These are free to download and install. Download the main one as it includes many standard Nissan ROM files and see if what you need is in there
I don't know anything about the MSA computer...but the Nistune goes into your existing ECU and plugs right into your existing harness. Best laptop? The one you have - but I'd day the more USB ports the better, so you can hook up other stuff (O2 sensor, etc)
@NYCZ31 so basically you are saying that when the engine is in WOT the turbo is loading the engine with boost the timing have to be closer to zero?thats interesting i didnt know that
hi man, great video, very useful, I see that the interface is quite similar to the one in romraider (open source for tuning subarus), so i would be a fairly easy transition, now my question is: in romraider there are target boost and wastegate duty cycle tables, I noticed that your demo did not include boost setup, I'm guessing because the turbo does not have any kind of boost solenoid and it's only setup externally (manual or avcr) . Does Nistune support any kind of boost level input?
hey man great video but i cant understand the timing part,is not supuost that the higher the rpms the more advanced the timing?why you say 3 timings for boost or i didnt hear well.
Hey buddy, I really enjoyed the video and it made me subscribe. Was just wondering if you could help me out on a few things. I have a z32 n/a and I defenitley need something like this because a standalone is just waaaay to expensive. As far as purchasing it, do i just need the type 2 board and that's it? (other than the wideband of coarse) And do send my ecu to nistune themselves or buy the board and send it to somebody to put it all together?
the wideband you've got shows up on your laptop, but do you have a small display to see your afr without having your laptop in your car running 24/7? :P
@JanoRS13 Email nistune themselves, some ECUs have boost control tables, others don't, their forums are very informative and Pete and Matt are very helpful people, I'm sure they will be able to assist you.
the only thing wrong with a r33 ecu is that stock, they are over sensitive and anything it does like it sends into r&r mode. but im gonna be getting nistune with my r33 ecu so i duno what other issues there would be. you would also need a z32 maf aswell.
@serchmarc Go on Wikipedia and read the entry for "Ignition Timing," it'll give you a good overview. Read the Nistune beginner's guide too, especially where it talks about editing the timing maps
Just Curious because I want to get one for my Z32. How much was the Tariff/Duty percentage for the import? How and where did you pay tariff/duty? Was the Harmonized Tariff Schedule (HTS) classification # 9032.89.60?
Nistune is the thing, i plan to get one for my CA18DET, first i need a notebook/laptop ^ ^ Is a innovate lc 1 wide band necessary? i dont whant to run nuts just about 200kW
One thing I didnt understand, you said in this video ''for example here the log shows i'm at 13:1 air fuel ratio and the map says i should be at around 12:1, so now i would change the k constant'' is that entirely true? From what I've learnt you dont touch the K constant once you've done your initial setup, you'd just adjust fuel values in the fuel map instead?
Hey NYCZ31 some how i ended up with your Z, i'm sure is the sameone, all the modz that you mentioned has been done to the one i just got, i will like to ask you some questions about the car, i got it without tune and before i start trying to make some power out of it, i would like to know what has been done to the engine internally, also about the injectors on this video you said their are 420cc but there is a video that yo said they were 440cc.
If the original ECU doesn't have the feature, Nistune won't have it. If you want stuff like that then a full standalone is what you want (or something like the AEM)
I don't think it does...though I think people wanting to use a MAP sensor are doing things that are beyond the scope of what Nistune does. They might want to go full standalone...
@NYCZ31 Where can I get an adaptor cable + software for a reasonable price ? Cadon Flash2 well over $1000 + dealer subscription fee for the software (out of question). Any thoughts/experience with BDM100 ?
fuelmap means -> how much fuel under how much throttle and how much rpm, right ? so you can set him up fat in lower rpms and thiner in higher rpms ? is there any comfortable method to set em up, or do you have to set each square?
Ok 2 things im trying to decide if i should go with an msa computer for my z31 or Nistune, which do you think is better? Also if i go with Nistune what is the best laptop for the program
Nistune becomes complicated when u put a maf sensor in the car that isn't in the predefined selections provided. I have a few quarrells with nistune also, in the sense that alot of the things in the program that are adjustable are in "units", they basically have no meaning outside of nistune. Failed to mention how to start tuning. You need to turn off o2 sensors (unplug them or turn o2 feedback temp high, or press 'o' key). otherwise changes u make will not have any effect good intro vid tho!
No it only works on OBD1 cars. So certain s14 ka24de doesn't work either. Only OBD1 cars are. Nothing built after 2000 to my knowledge is OBD1, They are all OBD2. Your solution there is the cobb accessport, or a ecu reflash. OBD2 is very different from OBD1. Question to the OP. Nistune doesn't support map sensors?
Keeping the MAF? Go Nistune. Going MAP? Use something else as your probably going for a power level that would be worth spending MUCH more money (more than 2-3 times as much as Nistune) for a standalone.
well, on dyno to tune shure , i mean can i use a aem uego or some thig else. did i need the factory o2 sensor, or should i mount the bosch lsu 4.2 in place or like seen on some skylines in a special pipe in the tail pipe. Too much asking, to lees tuning :)
Do you guys know if by any chance the 300zx vg30de (non turbo) transmission is compatible with the vg30dett engine?? I have a NA 300zx with the vg30de and the manual gear box and i was wondering if only swaping the vg30dett would be ok
So I have a Nissan 300zx z31 turbo everything is stock. I'm new to this whole concept on tuning so my question is is it worth getting nistune with all things stock? I'm not looking for huge gains but at least some difference?
Yes u can make a small difference if you get it tuned they can tune it a bit more aggressively than stock, but imo it is not worth it. Get some injectors, turbom fuelk pump, intercooler and maf then tune it and see massive gains
Turbo cars have detonation sensors but they are not sophisticated and have trouble discrimination high RPM vibrations from actual engine knock. So I would recommend an external setup to detect knock. I believe the latest version of Nistune can use the stock knock sensor but again it is not a great sensor especially on modified engines.
Fair enough. I got the free trial of nistune to have a look at the different aspects of tuning, and it seems to have both a standard fuel and timing map, and a knock fuel and timing map, presumably when it detects knock it falls back on this proven safe settings?
vanepico That's correct, but again we're dealing with a pretty cruddy stock sensor. When it comes to actually tuning your car on a dyno, I wouldn't trust it.
Geez man, youd want the afr in the 10s if you want to polute your oil with petrol and bore wash your engine to death, 12-12.5:1 under full load is were you wanna be,11s to be uber safe and 10s if you wana change your plugs every week. Good video though ;)
Man 10 years later and by far the BEST explanation, thank you man !
Thanks a lot for sharing this. Learned a lot more about tuning in just 1 video than i ever have before!
Very good video! Thanks for taking the time to post this up.
I have a NIStune'd S14 KA-T setup myself and love it.

For me, it was impossible to find one K-value that matched everywhere. 155 was good for low loads, but lean in high loads. 175 was good for high loads, but too rich in low loads. 165 was my compromise value, and I make adjustments in the few cells that need it to reach the AFR I want at that load factor/RPM/pressure level.

Nice! it will work for my Maxima. I will deffinately pick this up.
Only other person I have found try to do it to a maxima
I really enjoyed the informational video NYCZ31! I still got more to learn but I know I'm gonna run Nistune on my 240 w/KA24DET.
If you increase the K-value, it'll enrichen the whole table, but latency affects the AFR more near idle. If you lower AFR in individual cells on the fuel table, you're adding more fuel.

This has been a great help. I've bee looking into getting the type 4 for my s14 240, this has made it a buy for me. thank you.
VERY SWEET RUBDOWN OF THE PROGRAM! nistune should be sending you a check. very sweet z32 by the way. ineed to get this for my s13!
Thanks for uploading. This was very helpful back in a days when I started with nistune :)
I wrote "used car parts" on the customs paperwork, outbound to australia, and I think there were little to no tax. Coming back to the US, there were no import taxes at all.

Great video, definitely cleared up a few things!!!
With USPS, it cost $36 USD to ship my ECU to Australia. It took 4 business days to get there. Shipping back to the US will cost around $40 USD.
dam man you need to post new videos ,ive been waiting for ever for a new video
Great video and explanation of Nistune. I've been thinking about going Nistune for months now. Question is for those of us who currently has a romtune like enthalpy or emance.

@NYCZ31 so basically you are saying that when the engine is in WOT the turbo is loading the engine with boost the timing have to be closer to zero?thats interesting i didnt know that
Thanks for the reply. I've found a place where they sell them in the US. I will be ordering from there.
good vid man very usefull, just need my board now
hi man, great video, very useful, I see that the interface is quite similar to the one in romraider (open source for tuning subarus), so i would be a fairly easy transition, now my question is: in romraider there are target boost and wastegate duty cycle tables, I noticed that your demo did not include boost setup, I'm guessing because the turbo does not have any kind of boost solenoid and it's only setup externally (manual or avcr) .

@SHIFT2WIN1 I'm afraid I don't know, but if you go to the nistune website you can email them with all your questions.
Awesome video,
such rare infos to catch. Such rare to find the soft explanations while running!
Bonjour de France ;)
Thank you. Very helpful!
Yes, you can.
hey man great video but i cant understand the timing part,is not supuost that the higher the rpms the more advanced the timing?why you say 3 timings for boost or i didnt hear well.

Thanks for the upload ,very helpfull!
hey man great video,, just wondering if you know of a program for Toyota's
@combzcombz Thank you for the correction!
I'm using the Innovate LC-1 for my wideband
great video, thanks.
thanks for sharing
the only thing wrong with a r33 ecu is that stock, they are over sensitive and anything it does like it sends into r&r mode.
but im gonna be getting nistune with my r33 ecu so i duno what other issues there would be.
you would also need a z32 maf aswell.
@Dosalt Yes, go ahead
@serchmarc Go on Wikipedia and read the entry for "Ignition Timing," it'll give you a good overview. Read the Nistune beginner's guide too, especially where it talks about editing the timing maps
How did you wire in the wideband?
Just Curious because I want to get one for my Z32. How much was the Tariff/Duty percentage for the import? How and where did you pay tariff/duty? Was the Harmonized Tariff Schedule (HTS) classification # 9032.89.60?
Nistune is the thing, i plan to get one for my CA18DET, first i need a notebook/laptop ^ ^
Is a innovate lc 1 wide band necessary?
i dont whant to run nuts just about 200kW
YEa good vid. Wana buy my z31 Turbo? For parts or whole lol
@NYCZ31 since it's 1 year old will you answer if I ask a question ?
Not right now, but I'll get a gauge eventually. Money's tight right now:(
good vid
great video! :)
You can add A32 Maxima to the list I'm happy to say.
Only 95-96 ECU works though..
i gotchya. would you need a new sensor (not serial) or are there gauges that work with serial input?
One thing I didnt understand, you said in this video ''for example here the log shows i'm at 13:1 air fuel ratio and the map says i should be at around 12:1, so now i would change the k constant'' is that entirely true? From what I've learnt you dont touch the K constant once you've done your initial setup, you'd just adjust fuel values in the fuel map instead?

OBD2 came out in 1996.
You can do it while you are running
If the original ECU doesn't have the feature, Nistune won't have it. If you want stuff like that then a full standalone is what you want (or something like the AEM)
would that work for B13s?
why got no for nissan serena??sr20de?
I don't think it does...though I think people wanting to use a MAP sensor are doing things that are beyond the scope of what Nistune does. They might want to go full standalone...
great vidio 5 star ofc :)
@NYCZ31 Where can I get an adaptor cable + software for a reasonable price ? Cadon Flash2 well over $1000 + dealer subscription fee for the software (out of question). Any thoughts/experience with BDM100 ?
Do you have any issues with consult connection? Mine doesn't connect unless car running
fuelmap means -> how much fuel under how much throttle and how much rpm, right ?
so you can set him up fat in lower rpms and thiner in higher rpms ?
is there any comfortable method to set em up, or do you have to set each square?
hi, I can also use it in a d21 nissan pickup VG30E engine?
Ok 2 things im trying to decide if i should go with an msa computer for my z31 or Nistune, which do you think is better? Also if i go with Nistune what is the best laptop for the program
Nistune becomes complicated when u put a maf sensor in the car that isn't in the predefined selections provided.
I have a few quarrells with nistune also, in the sense that alot of the things in the program that are adjustable are in "units", they basically have no meaning outside of nistune.
Failed to mention how to start tuning. You need to turn off o2 sensors (unplug them or turn o2 feedback temp high, or press 'o' key). otherwise changes u make will not have any effect
good intro vid tho!
Alright thx yeh I'm probably gonna go with nistune just cuz its cheaper and you can do a lot with it thx
Do I have to cut out a usb port in my ecu?
No it only works on OBD1 cars. So certain s14 ka24de doesn't work either. Only OBD1 cars are. Nothing built after 2000 to my knowledge is OBD1, They are all OBD2. Your solution there is the cobb accessport, or a ecu reflash. OBD2 is very different from OBD1.
Question to the OP. Nistune doesn't support map sensors?
Keeping the MAF? Go Nistune. Going MAP? Use something else as your probably going for a power level that would be worth spending MUCH more money (more than 2-3 times as much as Nistune) for a standalone.
It's Nis-Tune not Ni-stune,alright lol hahaha thanx for the video very nice explanation alright.
well, on dyno to tune shure , i mean can i use a aem uego or some thig else.
did i need the factory o2 sensor, or should i mount the bosch lsu 4.2 in place or like seen on some skylines in a special pipe in the tail pipe.
Too much asking, to lees tuning :)
Could you reccomend any programs to tune a nissan sentra se-r 2002 with the QR25DE im having soo many issues with it
Do you guys know if by any chance the 300zx vg30de (non turbo) transmission is compatible with the vg30dett engine?? I have a NA 300zx with the vg30de and the manual gear box and i was wondering if only swaping the vg30dett would be ok
Send me a private message with all your questions and I'll answer them
Alright.
So I have a Nissan 300zx z31 turbo everything is stock. I'm new to this whole concept on tuning so my question is is it worth getting nistune with all things stock? I'm not looking for huge gains but at least some difference?
Did you ever get any answers to your question or find out anything else?
Yes u can make a small difference if you get it tuned they can tune it a bit more aggressively than stock, but imo it is not worth it. Get some injectors, turbom fuelk pump, intercooler and maf then tune it and see massive gains
Where do you get a 1984 z31 Nistune board? On their website they only list 1986+ from what I've found
When you are recording data, does it give you data from the detonation board? Or do you need an external stethoscope when advancing timing??
Turbo cars have detonation sensors but they are not sophisticated and have trouble discrimination high RPM vibrations from actual engine knock. So I would recommend an external setup to detect knock. I believe the latest version of Nistune can use the stock knock sensor but again it is not a great sensor especially on modified engines.
Fair enough. I got the free trial of nistune to have a look at the different aspects of tuning, and it seems to have both a standard fuel and timing map, and a knock fuel and timing map, presumably when it detects knock it falls back on this proven safe settings?
vanepico That's correct, but again we're dealing with a pretty cruddy stock sensor. When it comes to actually tuning your car on a dyno, I wouldn't trust it.
why not ROMulator? much cheaper.
Geez man, youd want the afr in the 10s if you want to polute your oil with petrol and bore wash your engine to death, 12-12.5:1 under full load is were you wanna be,11s to be uber safe and 10s if you wana change your plugs every week.
Good video though ;)
