Yet another color map for EcuFlash

Perhaps another color map for EcuFlash might be interesting? I wrote a little SageMath python script to generate a ScoobyRom-like color map file.

Note: Although generated color map matches ScoobyRom’s precisely, EcuFlash applies colors based on “min” and “max” specified in XML definitions.

Excerpt from EcuFlash definition file: 32BITDIESELBASE.xml

<scaling name="ChargeAirPressure" units="kPa" toexpr="x" frexpr="x" format="%.0f" min="0" max="255" inc="1" storagetype="uint8" endian="big"/>

Whereas ScoobyRom scales colors ranging from a map’s actually used mininum and maximum. For example, if you would change min="0" to min="100" in above scaling definition, low value colors would appear bluish like in ScoobyRom, effectively making map graphics cover more/most of available color range.


1) Download file scoobyrom-map.odt

2) Rename downloaded file to, since normal file extension is not allowed on

3) Move file into EcuFlash’s color maps folder, i.e.

C:\Program Files (x86)\OpenECU\EcuFlash\colormaps\

4) Launch or restart EcuFlash.

5) Via EcuFlash menu: File → Options → Appearance → Default Color Map
Select “”
(Btw., default color map directory can also be defined in Options)

Color Map File Format

Color map format is plain text ASCII file, usually 256 lines as in this case, specifying RGB values which will be applied to maps, from low to high:

153 153 255
153 154 255
153 156 255
152 157 255
255 110 103
255 107 102
255 105 102
255 102 102
