Everytime I change gears, AFR turns lean

Dear Matt and other experienced users of Nistune. During my tuning for my BCNR33 with R32 ECU, I always notice a strange thing. The existing map is fine but I find that whenever I change gear, no matter shifting up or down, the AFR will always get lean for 1-2 second during the change (say from from...

Re: How to convert wideband 0-5V analog signal to 0-1V ?

Dear Louis, I'm from HK too and use the Nistune to tune my GTR33 my for some years. If you want to use the wideband to replace the narrowband O2 signal like I did. You have to use a wideband system that equipped with narrowband simulation output like Innovate, Zeitronix, etc. I use Zeitronix and its...

Re: Questions about GTR32 Type II Board on GTR33

So, if I use R32 ECU for a BCNR33 with R33 narrow-band sensors in, the close loop control will work properly if I ground the pin 115? I'm using wideband simulation now but keen to know it. Aren't the 02 signals from R32 and R33 O2 sensors basically different. I've heard that one is voltage signal an...

Re: Knock count firmware

Any progress on the release of Knock detection function for RB26? I'm using the R32 ECU on my R33. Constantly there is no knock count shown whatever my timing is. Focus at the moment is on other software features so knock detection has been put on hold whilst sorting out the latest stable release. ...

Re: Knock count firmware

Dear Matt, Any progress on the release of Knock detection function for RB26? I'm using the R32 ECU on my R33. Constantly there is no knock count shown whatever my timing is. By the way, if I install an aftermarket knock control module like the Gizzmo or Phormula, is it possible for the Nistune to ac...

Re: Knock count firmware

Dear Matt, any update on the knock control for BNR32 ECU? I'm using it on my BCNR33 but it seems that the knock count based on the signal on stock knock sensors was just not working! I notice that I all along get 0 knock count no matter how I adjust the timimg!

Thanks and Merry X'mas

Fuel enrichment during Accel. & knock detection for RB26

1) How can I do instant fuel enrichment for sudden acceleration after down-shifting?? Or should I simply play with the master fuel map and make the necessary enrichment according to the load/rpm?? 2) Would also like to know what knock detection device/set-up is good for rb26 (BCNR33) tunning. I'm us...

Let's share your experiences to map a GTR RB26DETT!

I got a Tomei System 2 mapping for RB26DETT (BNR32) for: - Stock to 8.3 compression ratio; - Tomei Poncam Type B 260 IN/EX 9.15 lift - Nismo 555cc injector; - Nismo Uprated Fuel Pump - GTSS/34N1 Turbos It should be a good base map to start from! The low-rpm and upper-rpm're OK but I find that it's t...

thanks. i'll have a look at it. strange problem Matt, it works fine now...

Strange but no big deal!!! Sor...

Some Problems in the Latest Update....

Dear Matt, I updated to the latest version 0.9.13.12b recently and found that it's imposible to adjust the injector multipler, latency, O2 feedback temp etc. while the Wideband display is running now. If I close the wideband display, everything's fine! It used to permit the above operations in the p...

Questions about GTR32 Type II Board on GTR33

Dear Matt, I'm using the type 2 board of GTR R32 on my GTR33. Now running on Tomei System 2 timing map to pay safe and made fuel adjustment with a Zeitronic wideband unit. It gives a safe and average run so far and more fine-tunning will be needed. I have the following questions: 1) I notice that wh...

But as I read in the tuning guide, the flag can be used to turn off the close-loop 02 feedback, right??? How can it be done??
