Any new theories Matt? Pretty much out of ideas. New o2 sensor arrived today, but that isnt a solution. Wont have time to work on it the rest of this week, as I'm taking my S13 endurance racing all weekend. But Id like to have some things to try when I get back in town.

Good suggestion with open/close tables. Should be easy to implement http://www.nistune.com/mantis/view.php?id=178 Which hotkeys were you thinking of. I have a list of them (use F1 to show all current hot keys). Maybe I show this from HELP also? There are +/- and PAGE UP/DOWN for the increase and de...

As someone who has used many different tuning solutions, over quite a few years I have a few suggestions to help smooth the interface to make it more user friendly. Some may have been mentioned before, some not. Click open, click close tables. When a table in selected from the list of tables on the ...

I had a very similar issue with my Nissan Stagea Story goes, the 02 sensor was dead so I bought a generic sensor that was advertised to work with the RB25 Neo. Car ran OK for a week or so then started to do some strange things. Cold start and initial driving was fine. As soon as the engine came up ...

Is it possible that its dropping to overrun fuel cut mode at such small throttle input levels. As far as I can see the TPS is registering fine, and it reads closed throttle, when its closed, and the closed throttle warning goes out with the slightest throttle input while stationary. I know that ITBs...

I mixed up the tables. I adjusted the TP load cut. I dont think Ive touched Fuel Cut table. Ill have to do some comparing. If the Max load table is set high enough not to overrun, it shouldn't matter right? It looked really funny to me being at 255 for half the table. I only recently changed it afte...

I'll go pull some more logs in a bit. I've a hunch to test first. I tried pushing max load all the way to 255, it actually seemed to make it a bit worse, maybe because of the drop in resolution. I'm not sure. That system functions a bit different from the Subaru/Group N/Standalones I consider my for...

I was able to get the o2 sensor functioning this evening. Turns out someone had damaged the base of the sensor, and the signal wire was beginning to short to the heater circuit inside the base of the sensor. I was able to separate them for now, but it needs a new sensor in the long run. Fuel trims r...

Here is the newest revision of the file in the car now. Rescaled load limits and whatnot. Also started set up of the flex fuel/timing maps. Idles and cruises pretty much dead nuts on stoich when warm. Need to work over the fuel map now that Im happy with my K,TIM,Latency tables. WOT is a pretty soli...

It's an JDM import. No history really. I concluded that the emanage was there to compensate for the FMIC manual boost controler and downpipe. As far as I could tell, everything else was stock. I had No interaction with the car before Nistune install. The Emanage was disconnected, and Nistune board i...

Here is a copy of the retry rom based off the 54COF *** FP rom thats in the rom pack. matched the one that was preloaded to the board when I initially connected.

started over with a fresh rom tonight. made injector change and maf change. Tweaked latency, and TIM a bit, then pulled these logs. 1111_2017-06-26_2054_33.csv NIStune_2017-06-26_2051_32.csv wideband isnt currently linked to the laptop, but I may go through that trouble if I have to. Dont have anyon...

Ok, get ready for a long read. First some backround. I'm a professional mechanic with more than ten years of experience, and lots of time spent diagnosing issues. I've also been building and tuning Nissans and Subarus for many years. My experience with Nistune specifically is limited, but I'm well v...
