Re: S14 SR20DET 69F00 issues

What is the timestamp of the lean spike? I don't see it showing 15:1 AFR in this log

Re: CA18DET deceleration issues

Fuel cut / recovery is between 1200rpm and 1100rpm at 80 degC. Not sure where you read at 900rpm?

Re: stock BNR32 GTR hitting max load?

You can post the log here. It seems that's the way Nissan intended it from the ECU side of things. We use the standard maps from their ECUs in our boards With the boost sensor, you will not get one with 12V power. You can either use the 5V power and ground from the ECU (goes to the TPS switch) and r...

Re: Loading Old Bin into New version of Nistune

Because K constant is too low. What I mentioned below is that it should be value of 212. However you have it 119 (half this). Maybe you resized the injectors twice? After starting, and after crank enrich decays, it then leans out. Put K constant to 212, Throttle enrich map to factory values (File > ...

Re: Scaling issues on high res laptops ?

Code with font scaling was not disabled, but any tables with more than 3 digits would not use the font scaling, since too many digits would cause trunctuation of the display (eg 2000rpm might show 200 when enlarged) I've done some code updates today to adjust the fonts row by row. This means that th...

Re: stock BNR32 GTR hitting max load?

ECU is limiting the fueling from load calculation from 3200rpm above load 88 it would seem, to then make it only add more fuel solely from the fuel map rather from any extra boost (if any)

Which is interesting, since load capping at 88 also matches the load max in the fuel map at same value

Re: stock BNR32 GTR hitting max load?

This is the sensor you want. Now made by NXP (used to be Motorola/Freescale)

MPX4250GP NXP SEMICONDUCTORS $14.67AUD
EAR99 Pressure Sensor 0.2V to 4.9V 0kPa to 250kPa Gage A

I got mine from Arrow electronics Australia, but should be available elsewhere (Digikey, Mouser, Element18 etc)

Re: Scaling issues on high res laptops ?

Windows auto resizing fonts only works with menus and dialog boxes, but not any grid or graphics. The main maps will font scale with increased window size, but the tables at the moment are not enabled. I'm not sure why it was disabled. I'll have to check over the code again and see what is going on ...

Also don't adjust throttle enrich (VE) maps unless you have acceleration enrichment issues in one particular area of the map

Re: Loading Old Bin into New version of Nistune

Would like to compare against the one you downloaded (and then tweaked and then didnt work) I've copmared this against factory 70F00 S14 KA24DE but nothing jumping out From 275CC to 333CC then K would go from 257 to 212. Is that what you are using? If you increase K higher, does it then start workin...

Re: stock BNR32 GTR hitting max load?

Yes log file would be great. Even if you are hitting the end of the fuel map, what about the timing map? What TP max are you seeing (log would show this)

The fuel map scales are normally shorter than ignition scales and it will just use the last column values, which should be okay
