RPM fluctuating on the app

[Ptbug123]

In the mobile app the tach tool (needle) is showing a rpm fluctuation. It only shows on the needle it does not show on the rpm readout. Mostly for this forum I wonder if there is a known issue with the app showing the needle bouncing. I tried to upload a video but the forum wont allow the video upload. If there is a file format that is allowed can someone advise?

What are you using this with?

Super new here but it is a Kpro. The car is a Honda element with a boosted K24.

Datalog using Kmanager and send a datalog showing what is it doing.
