The ignition timing is a function of the ECU, and will vary wildly depending upon fuel and driving style.

What did you use to check it?

As said, the ECU controls all this, so i wouldn't worry about it, it's only idle after all. Try a reset of the ECU if your concerned, see if it alters.

Only way to alter it is with a piggyback ECU.

its something like a small PDA stuff, call OBDII automotive diagnostic or something like that which can check the ignition timing, airflow, and many other stuff.

Or a standalone like Power FC  s;) ;) s;)
(I'm sure you knew that, but just in case everyone doesn't)

No, that's only an AirFlow Converter...you can alter the MAF signal, which causes the ECU to dump in more/less fuel.
