Thank you for your reply.
Glad to hear it's normal. Then my wiring is propably ok.
I was thinking that the variation on the readings is caused by the closed loop operation of the efi. The mixture is constantly changing between lean and rich, as the oxygen sensor gives feedback signal.
That user-configurable update rate would be nice.
I mean it would great if it could collect the data for few seconds and calculate the average from that data. Not just update the display at lower rate.
