Automated Engine Analysis?

I would just import it into Excel or Libre Office. I would then use the charting tools and conditional formatting to highlight data of interest. You can probably get the log data in CSV format from the G3X.

Once you are fmailiar with the format of the data, you can add some limits to your spreadsheet and then use that to conditionally highlight data that is out of range. You could also record a macro to automatically import your data add the limits and draw the graphs.

After a bit of Googling it would appear that someone has kindly done this for you here https://rv-14a.blogspot.com/2020/05/avionics-new-grt-flight-data-analysis.html

Well, I can view the graphs on Garmin's logbook page and see if things are out of range.  The spreadsheet would be more automatic for that, but I'm looking for more intelligence than range checking.  I'm looking for strange oscillations and comparisons to historical data.  Like what Savvy Analysis does.

Hey Craig, I emailed Savvy and they confirmed they offer their analysis services for Rotax 9 series, too.
