Mr. Matt take your time and thank you for all the time you have put in helping me troubleshoot this.

Tonight I went through most of the Expert Parameters and set them to 0 or 255 to see if I can find one that changes the behavior with out any luck. I also corrected the "Neutral Position" sensor via hardware such that the flag is never on thinking this might fix the lean issue and that had...

You need to post your tune as well (.bin file from nistune) such that we can see all your parameters at work instead of analyzing the Excel spreadsheet.

Adjusted latency to 850uS and offset fuel via TIM, no luck, still lean for 1 second and stalling at decel

Turned off O2 Sensing, still lean for 1 second.

Not sure what else to try. Any Ideas?

Version 1.2.83 Remove address file commenting Update internals for WORD processing (replaces BYTE) Add extra map definitions Fix updates from 1.2.82 (variable grid size, table interpolation, AFR/PW display) Add EGR offset to 32K ROM files Next beta version update Mr Matt, I get all 0s in all Cells ...

No success on the new "EGR" Map, still lean for 1 sec then injector time spikes to where it is supposed to be. I used the MT Image and copied the Fuel Map, Timing Map, and a few other TP related parameters keeping everything the same, and the issue still persists. I attached a new log and ...

Very exciting! Thank you for looking into this. Ill get to it tonight I too think it's related to the Auto ECU code or some throttle enrich table we are not seeing. If this is true then the 20 year myth that you can use an Auto ECU with a manual transmission will go out the window as there were some...

I'm running Subaru STI yellow injectors which are about 500cc but have a latency of 1050us (source: Subaru forums) which seems a bit high considering nissan 500cc injectors are about 700uS. I'll try lowering the latency down to 800us and lean it out Via TIM to see if that has any effect on this lean...

Hi Matt, I would like your help again in identifying the parameter that is causing my lean partial throttle for a 0.5 - 1 second after applying throttle (ex. shifting gears) Capture.PNG . I can see the AFRs go lean as I step on the throttle, feel the power go away, and then comeback when the "E...

Using Nistune 1.2.82 and a PLX AFR and Boost module in a chain, I had 0 connectivity issues over a 2 hour period, in both tuner and streaming mode.

Using 1.2.82 and loading in a S13 KA24DE FP Map, the "Estimated AFR" function seems to be translating incorrectly.

See attached screen capture.

I keep getting an update error going from 1.2.80 to 1.2.81 via auto feature. I have attached the crashrpt and crashdump.


Any help would be great

You can also pipe the 10bin serial stream into python via COM-X, parse it into a Nistune Supported Wideband stream, and pipe out via another COM-Y. Then configure Nistune to use a sported Wideband and select COM-Y as the communications port. See http://forum.nistune.com/viewtopic.php?f=31&t=3549...

It seems as though my connection is more stable than the other user, but still disconnects about 2 min into streaming while driving the car. Ill have to capture some logs and so some troubleshooting whether the issue gets better with Daisy Chain vs Single stream modules. Ill report as soon as my car...

Finally got around to starting the car and tuning. I started with a KA24DE base tune, resized injectors + latency for Subaru yellows (535cc 1050uS latency) by selecting "TIM" + "Crank enrichment" option in the "injector resize" window. The car started right up. Took it ...
