nistune????

[sydwayz]

i want feedback on nistune from people that have had it already or have deeply looked into it.

[Buddyworm]

I love it to itty bitty little pieces. It's essentially rom tuning but with all the on-the-fly perks of standalones like the PowerFC and it keeps the on-board diagnostics function. The Japanese have been making unreasonable amounts of power with rom tunes for years but Nistune boards have the added ability to datalog every sensor attached to the engine. Hella useful.

About the only thing I can think of that Nistune can't do is stuff like MAP sensors and the unique pluswidth adjustments for each injector some high-dollar standalones will do.

[21FOX21]

I give it 2 thumbs up. Only thing I don't like is the no MAP sensor option. Some type of launch control would be nice also but besides that it is great.

[sydwayz]

how adaptable is nistune to switching out turbos, injectors and such on the fly?

[Buddyworm]

Very. K-value, Load/rpm scaling and fuel/ignition tables are both easily editable.

[sydwayz]

how much did u spend? did u have to send them your ecu? im pretty much gettin that fo sho

[Buddyworm]

I spent about CDN$420 and had a dude in town do the soldering for me so no, didn't have to send them anything.

[sydwayz]

what kind of numbers are you guys pushing? im assuming u guys are running z32 mafs? what do you guys think of a t3/t04e 60 trim non bb?

[21FOX21]

Yeah I am running a z32 maf. I am putting out 401hp 342tq t3/t4 57trim non bb that was at about 25psi

[zil40]

were did you get your nistune what shop im looking at buying one and need to no were

[sydwayz]

hey 21fox21 what exhaust manifold are you running? where did u get it from? yeah where did you guy order nistune from? where do you guys suggest i get a z32 maf from?

[XTCshri2222]

i like mine, installed about 5 since mine.

[21FOX21]

I ordered it from Nistune.com

Custom log style manifold. TrevTec made it. I got lucky and found a z32 maf at a local junkyard but they are all over Ebay is you need one soon.

i like mine, installed about 5 since mine.

so you must be comfortable with it & have good success.Were these CA18 installs ?Did you tune them as well ?What sorta power/setups are these/your cars making ? I'd think Nitune pops up as an option when looking into the 300hp+ range.Sounds like, "u da man" then - lol

[sydwayz]

it better be able to handle more than 300hp! where did you hear that?

[Buddyworm]

[sydwayz]

oh i know ive already seen all that i just wna know who says its only good for 300hp

[dash]

you said its only good for 300hpdash said 300 PLUS is where one would start looking toward custom mapping tools... like the nistune etc.

[sydwayz]

ha i miss read that i get what ure sayin now

[dc1984]

i noticed that some of u were saying that one of the biggest negatives was that u cant hook up a MAP/boost sensor to it. i have recently been researching nistune to use myself and there is a way to hook up additional 0-5volt sesnsors.this product allows additional sensors:

http://www.dlpdesign.com/usb/dlp-io8-ds-v15.pdf

as of now, i believe that this is the only thing that can be used for adding additional sensors to nistune. only costs like 30 bucks too.

pretty much, it requires something that sends a 0-5v sensor(output).for example, the aem eugo wideband sensor has a 0-5v output wire that could be plugged in to this(as well they also have that serial cable that can just be pluegged into ur laptaop via serial slot or serial to usb adapter)but how does nistune know what that 0-5v output reading mean? that is where u come in. u need to get a look-up table describing what the voltages represent. for example, if the aem output signal sends a signal of 2.35 volts, that voltage is equall to a particular A/F ratio reading. but there is a whole chart that u would need to get and input to make it as accurate as possible. shouldnt be too hard, just an email to the manufacturer shou;ld easily be able to send you the table.

it is prety much the same thing for map/boost. u would need something that could send an output 0-5v sensor. i believe that some electronic boost controllers do this like the AVC-r and whatnot. same thing goes for the look-up table. just email the manufacturer for the look-up table, and input the information so that nistune will be able to turn the 0-5v reading into boost numbers to show up on ur maps.

might sound a little confusing and it kind of is but it starts to make sense after a while. i got all this of the nistune forum. u dont need to be a mamber or anything to search and read previous threads.

just thought id throw this out there for the people who were discouraged about not having a map/boost sensor

[Buddyworm]

The problem with Nistune and using a MAP sensor is that nistune is essentially real-time rom tuning, which means it uses the stock ECU firmware so running a map sensor would involve changing the ECU firmware. I believe there's a dude on hybridKA or something that's got a MAP sensor working on a KAE ecu. Apparently the KAE and CA ecus are similar so conceivably we could have the option of running MAPs with nistune in the future.

The DLP converter posted above really only works for datalogging peripheral devices in the nistune software. It doesn't actually hook up to the ECU.

[dc1984]

the datalogging is realy all i said it was good for which i think would be a good additional asset to tuning your car(even though i have never tuned a car myself, just a thought!). although i have read a thread or two in the nistune forums about somepeople experiminting with using nistune for boost control.they were talking about using silenoids and air restricters, sounded pretty confusing to me but it is out there. and i know that nistune is constantly upgrading their product and making it a better tuning device. its unbelievable how active they are in there forums and there responsivness to questions and problems. as far as i know, the best customer service hands down.

but even though its not directly used for controlling the boost or anything, just get a good boost controller fro that. would that not do the job that needs to be done?

[dc1984]

talk about people rigging up launch controls and matt saying he wants to do it in the future:

http://forum.nistune.com/viewt...ntrol

a thread on using ecu for boost control, again verry confusing for me:

http://forum.nistune.com/viewt...ntrol

another thread talking about boost control:

http://forum.nistune.com/viewt...ntrol

bottom line is that nizune is the shiznit. it has come a long way in the 3 years it has been developed, and still has many ways to improve in the future. and it only costs a fraction as to some of the other standalone ecu's out there. matt is god

[21FOX21]

The a few single cam ka guys have map sensors working good because they also have air temp sensors already but the people that I have talked to that had map sensors running on CAs say that it runs s***ty because there is nothin giving the intake air temp. That is why I am still using a maf for now.

[sjbsuperman1425]

i've been reading their PDF. files on their website and i pretty well understand all the different maps and what not. the only thing im confused about are the map cell and "X" axis values. like i know the left side is for RPM, but are the numbers that you are plugging in just to raise or lower of what it currently is?

im looking into getting NIStune when i eventually upgrade the MAF and injectors later on, since its a bit more cash than a SAFC, way better, and its basically a standalone.

[Buddyworm]

The cell values themselves can represent a variety of things depending on what map you're looking at. They always pertain to the ECU function they control. For instance, on the timing map the cell values represent degrees before TDC. Or on the TTP Max/Min tables they represent maximum pulsewidths for various engine load states.

The x-axis values, once again, depend on the different functions of the maps. On both fuel and timing maps it represents the TP scale or engine load scale. The ECU uses the signal from the MAF along with several other variables (like K-Value and the VQ table) to calculate the appropriate TP. Another example is the Temperature Conversion table where the x-axis is a scale of voltages correlated to the coolant temperature sensor.

[sjbsuperman1425]

ok so.

Fuel Map:Y-Axis - TP (theoretical pulswidth IIRC?)X-Axis - RPMIndividual Cells - represent??

example (page 13 in NIStune mapping guide):the rpm is at 2400. the TP value is 8, and the cell for the cross axis is 10. im curious to what the 10 represents. i know that when the cell value is changed the injector pulsewidth should change. Is this basically the same concept as the E-Manage and the SAFC like you are giving and taking points, while monitoring injector pulsewidth and a/f ratios?

side question: since during fuel map adjusting, it says to disable the O2 sensor, it only means from the ECU from reading it, and that you still monitor the A/F ratios with this correct? Thanks a bunch.

[Buddyworm]

In Nistune the cell value literally represents "how much of _____". Like in a timing map the value in the cell represents exactly the number of degrees the sparkplug should be fired Before TDC, "fire the sparkplugs at X* BTDC". It's a little more complex with fuel but the numbers in the cells also directly influence how long the injectors are held open, "hold injectors open for X nanoseconds."

And yes, they do mean prevent the ECU from reading the O2 sensor. This is to keep the ECU out of closed loop while tuning because it basically ignores the maps when it's in closed loop.

However, the sensor they are referring to is the standard narrowband sensor which isn't very good for tuning purposes. You should use a wideband for tuning your maps but it doesn't actually feed into the ECU.

[sjbsuperman1425]

ok i think im starting to understand this better. i'll re-read the PDF. files tomorrow and see how it goes. Thanks Buddyworm

[Buddyworm]

Werd. Always happy to spread the tuning love around.
