Nistune Forums

Alrighty, ive been messing around with Nistune for a good week now and finally got a hang of things. I have a couple of questions though.

Alrighty, Im putting in a New turbo (Holset HX35W) and thus are having to create a new downpipe from scratch, its going to need 2 bungs and 1 hole. The hole is for my EGT Gauge, and the 2 bungs are for the stock o2 sensor and the AEM UEGO Wideband o2 sensor. Is there ANY possible way to use only the wideband o2 sensor for both o2 feedback and my AEM Gauge?


Next, Im thinking about tuning from scratch all over again, I finally understand (I think) that the ADR File is used on nistune so that nistune can access this to know what to do?
I then understand that the ".BIN" file is the actual "image" that the ECU uses access fuel maps etc...

Now heres my confusion?
I need a bone stock BIN file of a bone stock 87 Turbo Z31, but I cant seem to find one anywhere?

I want the stock BIN so I can start fresh from scratch and modify from there. How would one go by doing this?






Also why does the ECU pull timing to 10 degrees of advance on cold start, this allows me to NOT be able to drive the vehicle until warmed up, and its VERY annoying to say the least... i thought it was a flaw in my "tune" but came to find out that everyone in "test results" forum has the SAME problem but NO ONE seemed to fix it or say anything about it!
its like they all disappeared?

If your AEM UEGO supports a narrow band output then you plug this into your ECU instead

NIStune will read the wideband O2 sensor reading from the UEGO output for display in the wideband window

I'll put up some BIN files tonight in the releases area so you can have a look at those

Those were old posts that Jason and Bryant (Stinky) from Z31 forum made. You could ask them on z31performance.com if they had any work arounds for the timing drop

Awesome.

Ok next question.

Whenever someone posts a .csv (playback file), and lets say for example I put MY csv file for download, and someone else opens it and watches it.
Well whenever the video is being played in nistune, it shows THEIR tune being played back with MY csv file, which obviously isnt going to do any good.

So how can people post there "playback" files and expect people to watch them without posting there BIN file as well?



One more:
Why does fuel temp go backwards?
Example: Start the car, fuel temp "98", then as it warms up the value goes LOWER, i dont understand?

With the maptracing, even if the tuned maps are different but the scales are the same, the cursor will still follow around the same areas if the same address file is used

But if you used a HCR32 log file on a Z31 address file then this wouldn't make sense becuase the map tracing locations would be different... but other raw consult data recorded (batt, temp, AFM etc) would always be the same regardless of ECU type so you can still view that information the same

Dont know about the fuel temp. Perhaps one of the other Z31 guys know about this. We dont have it on CR31 so its difficult for me to know

the fuel temp gauge on my 84 z31 ecu does the same thing. i believe its in the "to do" list for matt.

Can you guys post a standard logger file (not debug log) with the temperature included from start of run (cold) to warm

I would like to compare this against coolant temperature
