Power meter or Garmin issue?

I’m using Specialized double sided power cranks which are 4iiii.

I had a low battery in left crank, changed the battery and recalibrated using the 4iiii app. Calibration doesn’t work with my 530.

Now I’m getting strange power data.

Has anyone else had this issue?

  • I'm not sure I have an answer for you but those are some pretty weird results i.e. Balance 100%R and everything else Left.

    1. The new battery you put in might have been bad to start with.

    2. Remove and reinstall all software and connections for that PM.

    3. Check for 4iiii firmware updates.
