Default Fluctuation in PSI readout on Dynon EMS

Below is a link to a short video.

It shows the constant fluctuation that I get when in the cruise (on either tank) from the pressure reading (in pounds per square inch PSI). The engine is a 184HP Superior IO-360 with fixed prop.

I would be interested in what comments you may have on a) is this normal? b) if not what is likely to be the cause of this fluctuation? c) is it serious? d) any thoughts on rectifying it?, etc.

Thank you in advance for any comments and feedback

Try turning off your strobes or anything else that is intermittent. My Dynon Skyview does a similar thing. CHT's and oil temps vary in sync with the strobes or landing light on in pulse mode.

I haven't yet been able to fix it.

Default Sending unit

Tim, my Dynon did the same thing but it got worse...from 10 lbs to 30, so I ordered a sending unit from dynon ...problem solved. BTW, my airplane's 9 years old with around 600 hours on the engine.

Best,
