A bunch of load calculation related maps
Hi Peeps,

Been sitting on these for a while, they basically control how load is calculated, they are a bit of a work in progress, so the names might change as we work them out properly:

53040010:
Code:
<table name="ECT Compensation for Load" category="Load" address="55004" type="2D" scaling="Percent128">
	<table name="Coolant Temp" type="Y Axis" address="61016" elements="8" scaling="Temp"/>

</table>

<table name="Baro Compensation for Load" category="Load" address="60d62" type="2D" scaling="Percent128">

Rich has been testing the Ramp stuff - with some success:

If you want to stop the sawtooth affect of load @ WOT, change the "Load multiplier end when TPS decreased by % (hysteresis)" map from 0.4% to something higher.

Goog luck

Regards
David

Thanks T.


I was missing Baro16 in my 53040010 def (on my computer), but I realized that it's on my site.

Code:
  <scaling name="Baro16" units="bar" toexpr="x/200" frexpr="x*200" format="%.3f" min="0" max="1.1" inc="0.001" storagetype="uint16" endian="big"/>

I've been setting the "Load Multiplier when TSP Increase by %" and it's sister "decreasing" one to 1.2% for a long time now.

Again, thanks Tephra. (He sent me that map a long time ago.)

Brilliant, thanks for this, tephra.

Golden, I've defined "Load Ramp Rate #1 (Load > 75)" on your online DB, and have populated it for the most popular Ralliart ROMs.

I've prioritised this because of the recent discovery that the RA dixie-cup turbo spools way faster than the Load Ramp Rate can accommodate. Not good. The fix, though, is awesome. No more spool-up knock.

U guys speak Latin....I'm just trying to learn. On top of that, I'm on a different program too! I need to switch from Cobb ATR.

Richard, I got my car back so I'm gonna need ur expertise again when the time comes. Right now, I'm just redoing my fuel map so I don't get the damn code "lean mixture" again. My boost is almost set though.

You realize that I always do 5557 first, right?

Have read Richard's post and started tweaking Load Ramp Rate #1 with some positive results.

David, would you be able provide more information on the Load Ramp Rate #2 to #4? Under what condition are they used?

The two most important ones should already be up on goldenevo.com. Those are:

Load multiplier end when TPS decreased by % (hysteresis)
Load Ramp Rate #1

sstevojr, here is what I have managed to define for the 55570005 ROM. Not sure if you are using this, else just let me know which ROM ID you are on.

Code:
<scaling name="ReverseInterpolated_Percent255_1byte" units="%" toexpr="100*(1-(x/255))" frexpr="255*(1-(x/100))" format="%.0f" min="0" max="100" inc="1" storagetype="uint8" endian="big"/>
<scaling name="MIVEC Overlap" units="Degrees" toexpr="(x-32768)*0.01953125" frexpr="(x/0.01953125)+32768" format="%.1f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>

<table name="Load RampUP Rate" address="5D48D" category="Load" type="3D" swapxy="true" scaling="ReverseInterpolated_Percent255_1byte">
	<table name="MIVEC Overlap" address="625F4" type="X Axis" elements="8" scaling="MIVEC Overlap"/>
	<table name="RPM" address="625D8" type="Y Axis" elements="11" scaling="RPM"/>
</table>

<table name="Load RampDOWN Rate" address="5D4ED" category="Load" type="3D" swapxy="true" scaling="ReverseInterpolated_Percent255_1byte">
	<table name="MIVEC Overlap" address="625F4" type="X Axis" elements="8" scaling="MIVEC Overlap"/>
	<table name="RPM" address="625D8" type="Y Axis" elements="11" scaling="RPM"/>
</table>
Still trying to make sense of how these 2 tables works. Please share your findings.
