What your screen shot shows is a recording of 3 pieces of data. What you're seeing is a header at the top of the file (rows 1-4) that give some details about the log, and then the data starts at row 6 and each subsequent row is one recording of the sensor data from the OBD2 system. Even though the file is a .CSV (Comma Separated Values), your file is separated by semi-colons. Excel has a feature to automatically split out data like this into individual columns (not sure if the mobile Excel app can do that though). The graphs that you'd posted before seemed to show 5 or 6 variables being graphed, but your CSV file seems to only show 3 (perhaps you didn't have all of them checked for logging as I described earlier). As you scroll through the file is it always just 3 values separated by semi-colons or do the other values start to show up later in the file? Odd that they aren't time-stamped either, I'd expect a data log to have each measurement with a time stamp on it.
I"m not convinced TuneECU is the best tool to be doing this troubleshooting with. It's a programming tool. Even though it has the feature for data logging, it doesn't appear to be very well implemented. There are other android apps that can read your OBD2 data that may be better suited to collecting data like this (Torque is one that's highly regarded, although I don't have any direct experience with using it for this purpose).
You can probably attach the CSV file to this thread so we can take a look at it.
