I have a ME 7.5 B6 A4, I used AugB logger to do some real time logging on the lambda read out and O2Voltagewideband , I compared the two column as shown in the pictures, the values in voltage  at 1.7Voltage while A/F reading is at 1.1?  according to the lamda vs voltage, 1.7V should be 0.78Lamda ?

Also  pvdkds_w  BoostPressureActual, is it reading in mbar? which mean I should convert it to 1 millibar =
0.0145037738 psi ? so if I am at 411mbar = 5psi ? since we are above sea level I added 5psi-14psi= -9psi then covert to mmHg??
but according to this website

in the middle of the page right under **Target Filling** {KFMIRL}
there is a chart shown:

10mbar = 1psi?

is that what the ECU is reading?

DO u know anything about uulsuv_w o2 wideband voltage read out?  can i use to the picture V_AFR for the calculation

Please take a look of the picture I attached. I am confuse because the value on lamsoni_w bounds between 0-5  what is that mean? is that written in voltage?

If I can make a suggestion here, It might be more understandable if your engine was fully warm  before doing any logging, unless of course you are looking at adjusting warm up fuel.

You are right,  the graph I pulled actually is lamsoni_w which shouldn't be 0-5 . 

the thing is I didn't need any definition to create a log data? I only needed the bin ?that's why I am so confused

What is AugB logger?

Please stop posting screenshots, and post the actual .csv.

Also consider using ECUxPlot to graph them properly.

You're confusing a bunch of separate issues.

ME7Logger has an algorithm to find where in RAM various variables are stored. It is most reliable when used on stock images, not because it depends on the maps in the binary being stock, but because other modifications (i.e. to the code) can confuse it.
