Does anyone have the scalings or know how to setup the fuel map to read Lambda in ECU Flash? I have gotten it to somewhat work but I need to display the full number like .78 It just shows .7 and only allows me to move it from .7 to .8 or .9 ect. I need to be able to move the values more precisely.

Thanks in advance

Try this:

<scaling name="Lambda" units="Lambda Factor" toexpr="128/x" frexpr="128/x" format="%.2f" min="0.6" max="1.15" inc="0.0078125" storagetype="uint8" endian="big"/>

It is setup to color the maps between 9.0:1 and 17.0:1 AFR (0.6 and 1.15 Lambda)

edited the frexpr error, my bad.

Format: %.2f
Unit: Lambda Factor
ROM to display: 1.0*128/x
Display to ROM: 1.0*128/x
Data type: Unit 8
Display to endian: Big
Display min: 0.6
