I have a turbo underboost error when under really heavy load (towing uphill) and have taken a number of live data runs.

If I can get the data into a spreadsheet, I can make a multitude of diagnostic graphs to try and resolve the issue.

I would have expected the device to save the data as a simple CSV file, but I can't find any such files. I have found some files that look like they may contain the data, but the values appear to be encrypted

Has anyone done this
