air/fuel mixture

what is a good way to know A/F mix?
i know it can be seen by the color of spark plugs, but i am driving on LPG and i think it makes spark plugs looking white..meaning lean...of course when i am boosting i switch back to gasoline...

is there a way to see a/f mix using vag com?

Not accurately without a wideband lambda as far as i know.

yeah..however i dont need some accurate readings..only the fact if it is rich or lean...
