Retrospective OBD overlay

Kosborn

Hi, new to this and trying to merge data between RaceBox mini, GoPro, OBDMX+ through this. Hand a track day yesterday so used this for the first time but can’t find any of the data from the OBD. Did I need to select what I want to monitor at the time of use or is there a file stored so I can retrospectively add an overlay?
Thanks

You should see the OBD-II channels in graph settings etc. Use the "devices" screen that displays all the channels being recorded for trouble shooting. It's the green/red button at the bottom left of the Live recording screen. Also you should select the fast/slow channels according to this logic: https://racechrono.com/article/faq/what-is-the-difference-between-fast-and-slow-channels
