Default Re: FSI distributor issue

The idle jet is by passed just as you commented but the engine with all systems operating properly will idle very well with the full retard position of 3 degrees after top dead center which is where it usually ends up when setting up timing using the Ford method.
When idling very slowly, 350-400 RPM after the idle air adjustment is properly adjusted moving the GAV can have a usually small but noticeable effect on the idle quality after the engine and carburetor are up to operating temperature.
It has also been my experience that the FSI electronic ignition system is highly overrated.
