So that's from the document ... I think it does not make it clear at all what actually is going on.


If I understand you correctly a 'filtered value' of lets say '30' at TP 50 will not give the same mixture as '30' at TP 100.

Thank you, that's helpful. I think I know all the PDFs on there but to my knowledge none outlines the problem in bold writing. I just did a log Estimated vs actual AFR values.. My K is spot on, but as you said on higher loads the actual mixture deviates. What would you suggest to do to bring TP > 52...

OK, thanks .. I knew it was somewhere on this forum but didn't find it.

So is there still a point in setting the fuel map to a predefined value and adjust K to match these estimated AF ratios?
Also the autotuner must have some merit? (I've not used it yet)

I was wondering how the estimated AFR values are guestimated? If I understand it correctly you don't have any airmass values from the MAF sensors .. it's % vs voltage you have(?) Also there is no direct value for injector capacity (?) I might be totally wrong with my assumptions, would be interestin...

Thanks Matt.

I guess (as you say) just use line 19 (half blow)
Or just bridge 19+6 internally ...

Do you recall what value that SMD resistor has which was removed on Z32 ECU?
Is it important? Must be low ohm?

I was wondering if I could use Pin 6 of the Z32 ECU to switch a relay based on coolant temperature. Pin 19 is used for half blow fan speed, pin 6 for full blow. However Pin 19 (On Z32) is cut during installation since it collided with the RB25 Power steering signal. What's left is Pin6 as an output....

OK ... thanks!

Hi Matt,

Yes, but CTRL UP/DOWN flattens the map again ...

Can't you incorporate a key combination to directly decrease / adjust the offset manually ?
(as a hot fix option)

1.2.93 / W10

When zooming into a map (resize via CTRL-cursor) the map inconveniently leaves the window and is not fully viewable.
It seem the offset to its parent window is wrong ...

I remember this as a bug from many releases ago
Is there a way to move the map graph further down?

I'm just hooking in here, so are you able to log boost and afr in NT?

Thanks

So it's cold/warm crank enrich ..
Thanks!

Which of the enrichment tables is basically the 'choke' function? By that I mean the table that adds fuel till the engine has reached it's operating temperature. From the looks it might be 'Enrich (Cold crank)' or 'Enrich (Warm crank)' However the name would imply that it is only used for cranking? ...

Alternatively you could load the logfile (.csv) into Excel

With the latest version I noticed you made some sensible colour coding in the 'Copy' parameters windows.
(maybe it was there longer, but I just noticed)
Good job!

An island in Japan? Nice!

Anyhow .. are your injectors the yellow Nismo ones?
