IGN on idle jumping around normal?

[0piston]

Hi quick question before I add a datalog. during idle on my display I see my timing IGN jump around from 17-26 although in my "low speed ignition values all around idle are set to 20' degrees. anything i can quickly check that could be affecting this?

my "ignition compensation air temp (low load)" table under "temp compensation" are all set to 0, so I don't know why.

thanks.

Ignition timing will vary at idle, this is part of how it ocntrols the idle speed.
