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

 http://forums.vwvortex.com/showthread.php?5935270-UnOfficial-Eurodyne-Maestro-Tuning-Handbook&p=80423480&viewfull=1#post80423480

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?

411mBar is vacuum (ambient at sea level is approx 1013mBar)

No, just use lamsoni_w.

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.

Something is wrong with your definition.

lamsoni_w is actual lambda.

uulsuv_w is O2 sensor voltage and will be 0-5v.

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

Yes. ME7L can make a definition file for you based only on a bin... but it must be *stock* for best results. Some modified bins can confuse it.

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

Also consider using ECUxPlot to graph them properly.

Roger that!

my question is how can I verify the value for the lambda is correct if I am using a " stock map " I never downloaded a stock map for my car , I just loaded a stock map from a member posted on here, however pretty much i have to re-work most of the map to get my car run 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.
