- In this video I try to go over the basics of a street tune in Nistune. The 3 resources I used were:
!!!!****DO NOT USE THE "AUTO ADJUST LOAD SCALES" FEATURE****!!!!
I have not been able to get the load scales anywhere close by checking the box that says auto adjust load scales. its best to just look at them and do it manually.

After using the resize injectors feature the 1st step is tuning the k value. This is done while driving around 2000-3000 rpms while trying to stay at about a 1/4 load on the fuel map. You can either monitor short and long fuel trims (fts and ftl) if the narrowband o2 or simulator connected to factory harness, or by just monitoring the wideband gauge looking for 14.7 or close to it.
The 2nd main step is to adjust the load scalers. Look at TP (Load index) to find the min value at idle and max value at full load/boost and adjust the tables accordingly.
I took a few degrees of time out of the top end/high load area of the map as recommended in the Nistune literature.
It’s also required to “flatten” the fuel map due to bigger injectors. Do this slowly to make sure AFRs don’t go lean while in boost.
Using the trace map/graph is good for this because you can see what the AFRs are in the map after a run/pull.
This is just a quick guide to introduce some basic features of Nistune. - Auta a dopravní prostředky
Learned a lot! Great video brother
Mate, this knowledge is invaluable!
Been struggling with getting the z running for a while. I had no idea what was happening as my fuel map was in the wrong location in terms of trace. Your video has been the only source that has told me NOT to do the load scale adjustment. It seems when I clicked the "Adjust Load Scales" on my injector resize and on my MAF change that Nistune would absolutely destroy my Load values. Which in turn placed me in the wrong columns, giving me the issue I had. I thank you for the help!
Glad it was a little help. I’ve been trying to find the sweet spot on load scalers. You can always use the compare feature but it doesn’t show you the difference in value on the map just a visual on the 3D graph so I’ve been trying to open up nistune twice to compare load scales and fine the best values.
What was your issue? Mines running SUPER rich and horrible idle.
doing gods work my boy
This content is super helpful. Been trying to understand Nistune for my Z31T. I haven’t been able to get my aem uego to work with my Nistune .
Doesn’t the AEM come with its own connector (usb/serial) and it’s own software to read it in the laptop?
For Nistune you have to set up a com port on your laptop first I believe.
Then configure the wideband in nistune.
My prosport wideband didn’t come with a connector so I had to get the dlp a/d converter to wire the bare signal wire from the wideband controller (it’s in an older video). But the dlp converter have like 6 other ports so I could wire in boost level and other things to data log in the future.
More please! Very nice!
@@davidbergweiler4772 thanks! trying to at least get 1 video a week
Hey mate awesome video. Quick question. With the rpm limiter how does that work? I've tried to set mine but no good. Set it at 2k but doesn't limit. Is the limiter only under load and whilst driving as I can't drive my car on street yet?
This will help me get a KA-T S14 on the road again. It has been a nightmare.
Good luck man! Most important thing you need to dial in is k value and load scales from what I’ve experienced.
Hey mate my nistune consult won't connect unless car is running? Any ideas. Stock car besides battery in boot
OK, stupid question perhaps but if I have large injectors for future improvements can I get the car to run properly nd have good ARF values using Nistune? Right now at idle the AFR is WAY rich at 2.6. ANY input would be greatly appreciated. Thanks🙂
Hmm sounds like something is wrong… but should be able to tune bigger injectors as you do other upgrades
Hello! why do you change KConst when changing injectors? The manual says to adjust the TIM. The manual also says that you should try to leave Load Scales at their factory values.
TIM is only available in Feature Pack nistune which I do not have
Is there any difference between Nistune vs MS gold stand alone in terms of how old the car is? or is it limited to just stock components? Or can you run ignition timing LS coil packs .
Not exactly sure what the question is..nistune is a daughterboard that gets soldered on the stock ecu and essentially works like a piggyback but uses all stock sensors that the stock ecu would. Any stand alone ecu will have to be wired in to use some existing components and some new lots more possibilities with a stand alone.
Sorry I was meaning would it support aftermarket coil packs or does it have any limits.
Trying to justify spending a ton of money and time to mega squirt when my goal is no more than about 300hp or so.
@@TobeyNord no, nistune does not support coil packs. Yes nistune is limited. For just 300hp it should be fine though
Hey man where did you get your consult cable? Didn't realize I needed one before buying my nistune off of fb
Hmm I can’t remember, I got my nistune off fabo too and idk if it came with a consult cable. See if you can find one from digikey. That’s where I got my DLP converter to hook up my wideband
@@samwashere1392 sweet I'll check out digi key. Is the the dlp cable the only way to run a wideband on nistune?
@@zhongxina2793 no, I think aem and innovate have their own USB output from the their wideband controller. I think they come with software and in nistune you can just read the usb signal or something. The prosport wideband I have only have a 5v signal wire output from the controller so that’s where the dlp a/d converter comes in, converts that 0-5v signal to usb then you calibrate it in a nistune table
i got an rb20det i did a 2nd gear pull but my tp index is around 129 at 4800rpm also hitting a safety load limit only hitting about 10 psi on boost if i increase it up to around 130 on the fuel scales would it do any damage?
It sounds like you need to adjust load scales..need to be careful cuz if the timing load scales are off it could cause damage. Try increasing the top end of both load scales by 20-30 and interpolate referencing base map scaling. If not enough do the same thing again until your max load is in the 2nd to last column
@@samwashere1392 thanks ill try that!
Hey bro does it matter the build of the laptop to run nistune or no?
From nistunes faq page “- Recommended to run Windows Vista, 7, 8, or Windows 10 with USB ports. Both 32 and 64 bit operating systems supported. Minimum screen resolution 1024 x 768”
Can you explain what K constant is?
k constant is the injection multiplier, basically adjusts for bigger injectors. its only needs to be adjusted in the non feature pack nistune. nistune with feature pack has a feature called TIM (total injection multiplier) which is an easier way to make injector resizing adjustments.
Theoretical pulsewidth is basically the load measured by the MAF. The actual calculation is:
TP = MAF lookup / RPM x K constant
check out the support tab on the nistune website, lots of good info in the users manual and tuning guide:

@@samwashere1392 thank you so much for the reply
good luck with your tuning!!@@ejm3381
Eo you do tunes on teamviewer? 😅
@@Nexusmanomg we can fail together 🤣🤣😬😬
