Nistune Forums

I remember the number of windows in the settings was 10. I changed it to maybe 12, no change. I changed it back to 10, but it was still not working.

For the O2 problem, I will take a screenshot, if I get to see the same problem again.

I reinstalled NIStune and now I am able to open again ignition and fuel maps the same time.

Any ideas for this to happen?

I tried to search and google, but I didn't manage to get any hits, maybe with poor search string or just not discussed. Yesterday, (I remember getting the same problem before also), while doing some tuning I ended up loosing possibility to have fuel and ignition map open at the same time. If I have ...

This ended up being a grounding issue. Ground connection to intake from battery was cleaned, after that, the signal inside ecu was correct. Wideband unit was located behind radio and grounding made from there, so there was some ground potential difference between the wideband unit and ECU. Signal wo...

Really late update on this one:
I don't know what caused this issue. Issue was solved by changing to another ecu, maybe it was for RB20.

Today I had a tuning session for a S13 with modifications. I have made chip for the same car few years ago. Latest changes for the car was RB MAF to Z32 MAF and that was the reason for new tune and there was also now NIStune equipped ECU available for the car to use. Everything was fine when the O2 ...

I already sent mail to Teemu about it, waiting for a reply on that one. I will reply here if the problem gets solved.

Really interesting behavior, as 60 degrees of engine temperature is a complete show stopper on idle, but while driving, it works without problems.

This same ECU has now reached to the next owner and the problem occurs also with this one. Engine and ecu shutdown when reaching 60 degrees of temperature at idle. I suppose this car is having RB25DET Spec2 engine with spec1 wiring. At least it doesn't have PTU and TPS has two connectors but the wir...

It was Infinity J30 ECU.

I was working on a RB25DET with type 3 board in it. Car was running good on idle while engine was cold. After the engine reached 60 degrees temperature it shut down like it was turned from key. After that it was not possible to start the car without using throttle. Then it would idle for various amo...
