I'm sorry if this is painfully obvious, but I have looked through the "timing section" of the source code on $60 and through the maps in TunerCat. I have also searched here.

I can basically see that fuel/VE under boost and at higher RPM is handled with a multiplier. How is timing handled above 4800RPM? The main spark advance map seems to stop there, and I can see the boost spark advance correction vs. MAT vs. Boost table takes some timing out at higher KPA's.. but what is that being subtracted from? Etc.

Is there something I'm missing here?

Thanks!

 

It slopes in additonal timing.
Starting at RPMXHI, it will add ADVSLHI in degrees per 1,000 rpm.

RPMXHI: FCB 255 ;F1 Table Extension Hi RPM Breakpoint
ADVSLHI: FCB 0 ;Hi RPM Advance Slope

Obviously, it's disabled in the settings shown.

 

Ok. So, for instance, if that feature is disabled and the main spark map is set for 15° at 170kpa and 4800rpm... does that also mean that it will give 15° at 170kpa at 6000rpm, for example?

And if that is true, if at 70kpa boost the "Boost spark advance correction vs. MAT vs. Boost" map shows -5° for example.. can I expect 10° of timing at that boost level? (Of course, if I set it to slope in timing above 4800RPM, this would no longer be true.)

And finally, are these numbers taking base timing into account, or are they in addition to base timing? I assume that they are including base timing, but I just wanted to check.

Thanks again.

 

Also, is there a reason that, when I look at the bin file I have from the $60 source code in Tunercat, the "spark reference angle" is set to 70°, and the "maximum spark retard relative to reference" is -74.88°?

In the code I see:

MAXADV2: FCB 0, 85 ;Max Advance Relative to Reference

and

MAXRTD2: FCB 255, 43 ;Max Retard Relative to Reference

Does that "0" after "FCB" mean that the max advance relative to reference is not enabled? And does the "43" after "FCB 255" on max retard mean that 43° is the actual max amount? Or do those numbers have nothing to do with what I'm talking about...

Just want to make sure I'm not making any mistakes.

 

You need to reread the opening statements.

Before running the 60 code, you need to verify that it matches what it is you've run. ie, in every entry, and use the entries that you have been using.

At this stage, I'd suggest you stick with the stock 58 code until you get more familiar with what you're doing. Not meaning to *slam* you, just that it seems you've missed the point of the opening statements.

 

No offense taken. I'll look over it again and again until it makes sense. I don't see any reason why I can't make the stock 58 code work for me, my main concern at this point was to get an idea how timing was affected after the end of the main spark map.
