O2 and FT

[pouliotk2441]

Hey guys, I’m not sure if this is the correct spot but it seemed the most fitting. Have a ‘12 C7 A6, 3.0t with a HEX cable/UDS so I’m using advanced measuring. All the videos and posts I find are just using measuring blocks and with all the options for the things I need to log, it’s getting a little frustrating. I need to log both front and rear O2 voltages and short term/long term fuel trims… I’ve tried multiple different options for each and none of the values make sense so I’m looking to find exactly what I need to select to log all four O2 voltages and the LTFT/STFT by going through basic settings-> advanced measuring-> etc

Disregard basic settings.. was just walking around the house and realized I wrote that. Advanced measuring blocks***

Well then those are for pre-UDS ECUs.

I need to log both front and rear O2 voltages and short term/long term fuel trims…

Type oxygen sensor or Lambda probe into the search/filter box in Advanced Measuring Values selection dialog and you will find the sensor data you're looking for. Unfortunately, the terminology they used for these things isn't terribly consistent.

Type mixture and you will find both short term and long term adaptation values (aka trims) for both banks.

For example, this is what I’m getting. That was just a steady cruise. But also getting “undefined” on datazap for the only other front o2 sensor readings
