XML Formatting confusion

[New2Scoobs]

Epifan, could you (or anyone else that knows) post a few real life examples of how to correctly format statements in XML files.
I don't have a clue how (or when) to use the BigEndian feature.

Also, when you release updates with new & improved features that require us to modify of our XML files could you please also provide some real life samples of an XML file utilising the new feature(s)

We are not all programers you know!

Thanks

For Subaru ECUs you should pretty much always be using big endian.

OK, so that answers WHEN to use BigEndian - Now all I need to know is HOW to use BigEndian in my XML lines

I'm not sure exactly what you have, but any time you're using [byte0] and [byte1], reverse them. I'm not sure how much you know, but big and little endian tells the application what order to read the bytes in.

Add <default_reverse_bytes value="True"/> tag in <config> tag to change ecuEdit for work with big-endian numeric representation

OK that makes sense now. But after adding the above tag my RPM row and Engine load column data is now incorrect. Instead of RPM data going from 800,1200,1600 etc it is now listed as 204800, 307200, 409600.
Below are a couple of lines from my XML file - what needs to change to get the RPM & Engine load data correct?

<map name="Low Det Fuel Map" type="3">
<rows count="18" offset="#292b5" power="2" format="%.0f" func_2val="[value]*50" func_val2="[value]/50" desc="RPM"/>
<cols count="16" offset="#292d9" power="2" format="%.4f" func_2val="[value]/8192" func_val2="[value]*8192" desc="Load (Air/Cylinder charge)"/>
<data offset="#292fc" power="1" format="%.2f" func_2val="14.7/(1 + ([value] / 128))" func_val2="(14.7*128)/[value]-128" color_dir="1" inc_dir="0" desc="Air/Fuel Ratio"/>
</map>

func_2val="[value]/256*50"

that should do the trick

[x99percent]

func_2val="[value]/256*50"

that should do the trick

...and what about the load?

[value]/8192 no longer works with <default_reverse_bytes value="True"/>

it should work! something else maybe is out of order???

In the functions toRPM=[value]/5.12
I use only multipliers
toRPM=[value]*0.195312500000000

same logic for load [value]/8192 should work but in any case try this
toLoad=[value]*0.000122070312500

If I turn off reverse bytes for that axis only (reverse_bytes="False"), then [value]/8192 works perfectly.

it's not right! [value]/8192 is correct formula. Imho, you must shift offset to Load sequence by 1 byte.
