Yes, I noticed that too. Don't know why it stores outputs those low numbers.
I'm using the Ecotrons ALM board where default is 1.667V for Lambda = 1.
I actually hooked up an old analog meter and marked the 1.667V point and lean to the left, rich to the right.
So it's just the way it's stored in the EM3.
On the EM3 display that point displays about as one bar below center (appears lean). I need to adjust the EM3 software a bit.

Finn,
If you are using a wideband O2 it looks very lean.

I'm using it. But using the vDrive3. Had to modify the EM3 software to
get it to work. However, I may have a partly defective vDrive3.
Sometimes it's not detected on startup, sometimes it is.
In addition to modifying it to use all eight 2 volt and all eight 5 volt
channels I also modified the EM3 software to write a header (or label)
row the first time a new file is opened. I also change the
comma-delimiter to a Tab character (x09h). That means I can right-click
on a file and chose "Open with" and open with Excel 97 and all columns
are neatly there.
Graphs are easy to make in Excel 97.
Attached from one of the better engine runs.
I didn't continue working to make?? the EM3 software for the vDrive3 more
reliable. Instead I ordered an Arduino data logging "shield". I intend
to modify the EM3 software so that if no vDrive is detected, it simply
outputs the data continuously. The Arduino program I have in mind will
combine and store the data from the EM3, Dynon D-100 and GPS. Yes that's
a lots of columns in a spreadsheet, but I can easily write an Excel
macro to rearrange columns and generate graphs.
