Great video.
You can use Dropbox or Onedrive to load your data file and then post the link. But I'm now a little confused. Where did the csv file originally come from? After rereading your post I now realise that the csv wasn't generated by the Gopro and only captures rpm; not speed. What I think
we need is the data file from the Gopro and you export that file as a csv. What you have to ensure is that your speedometer is referencing the right data file and field. Also you may need to do a conversion to get the expected speed. Does that make sense? Personally I don't use a Gopro but the principal should be basically the same for all action cameras.
