Nistune Forums

I am currently running a GT2871 turbo , Injector Dynamics 1000cc injectors, Z32 AFM and e85. It makes 472WHP and 640WNM @ about 2 bar boost. Looking to upgrade to the GTX version of the turbo wich will flow ~80 more HP. I also think i will go for the Bosch 1700cc injectors, a little worried about ho...

That sounds nice! I am currently running e85 only but would like the flexifuel option mainly because it would be a fun feature to play with. Also I have a couple of friends who really want the flexifuel option. Another thing that is not a necessity but would be nice is the ability to see an estimate...

Great news!
I have the S14a ECU.
Any ETA on when this boost feature will be implemented?
Thanks!

I have a concern here, about if i choose to use the flexifuel feature.
Will i be able to let it control boost?
There is no way i can go full gasoline and still be running 2 bar of boost.

I have run ID2200cc injectors on a SR with Vi-pec, that setup also behaved like a stock injector. No problem at idle or cruise. It`s an R34 GTR with a R32 Nistune ECU i am interested in running this setup with. The reason i am looking at the Bosch 1700cc is that they are the most bang for buck injec...

Hi, i am planning on some new injectors in a GTR wich i want to run Nistune in. I am concerned about how well the stock/Nistune ECU would run these pretty big injectors. Does anyone have any input or experience on this? Several ECU`s struggle with rich idle because they don`t handle the low pulsewid...

I read that the TPS would only show 50% on the MFD.

Could someone confirm that the MFD will work as normal with the R32 ECU?

Are there any solution to the MFD problem?
Do i need dual o2 inputs? i will be running a wideband anyways.

I have searched but did not find anything.

Nistune seems to be the best option for the R34 but the MFD issue is bothering me.

If i understand this correctly i can send my Nistune ECU to Australia to get it flashed with the new firmware so i can get these new features?

I can just import my fuel and timing tables without any hassle afterwards?

This was solved, the problem was that the speelimiter kicked in.
After adjusting the speedometer the car worked perfectly.

I disconnect the speedsensor and it worked, I then installed the Dakota Digital speedometer converter device and adjusted it correctly. Still working perfect. A little odd that the limit is set to 201kmh but does not engage before well past 250kmh. Thanks for your help so far! Should I recall the sc...

125mph = 201 km/h.
speedo shows 260+ in third without any problems.
I will do some more testing tomorrow, thank you for your input so far!

I just remembered that the speedometer reads about double speed because of the z32 gearbox and sensor.
Need to install the speedometer signal converter.
Do the ECU use the speed for anything?

Only clutch and internals are different from last year, everything else is as it was.

Thanks for explaining!

I`m running E85, should have said that earlier.

So i have to re-tune/adjust the map if i change the scalers?

What is the function of these scalers and TP cut?
I am new to this and to Nistune.

Any theories of why this is an issue now, and not last year running the same setup?

Thanks!

Of course, i`m sorry.

I have tried messing around with tp cut / limit, no changes.
Maybe i should try to adjust the TPS?
