Data,1,obdii_data,timestamp,966956312,s,timestamp_ms,0,,pid,17,,raw_data,16,%,,,,,,,,,,,,,,,,,,,,,, => Not OK (Example for Throttle position at 16%).

Can you help me ? please.

Maybe someone can give me a .fit file with OBDII ?

I have no experience of obdii but your fit file seems to lack the some basic garmin ID messages:

File_ID

File_Creator

These normally precede the record

Perhaps there also should be an event of some sorts.

I´ll give you a fit-file with OBD II data, later.
Must have several around on my other PC. Otherwise I´ll just create one for you.

Created a file from my motorbike. If you need any further info or data, let me know!

Good luck

Thanks for the fit file which seem to contain mostly accelerometer and gyroscope data with some obdii time intervals - never seen one of those before but I see it needs to be linked to a video file which is done automatically by the Virb Editor.

I have no idea why this should cause the problem you've mentioned. Sorry :(

thank you a lot, i will study this.

There should be around 5-7 OBD II Messages per second. As you can see: RPM, Temperature, Throttle, Airflowrate and Engineload (which I faked for Gear). Also Speed, which is just zero, because my motorbike does not submit that.

Have you converted it with the SDK java tool? I made bad experience with the C# solution, which somehow did not cover any OBD message. But it was some time ago...

I used my own vb program to analyse the content of a fit file and at times check the units of unknown fields with the sdk tool.
