NO GAUGE THAT USES THE STANDARD SENSOR IS WORTH A WANK


A narrow band gauge shows RICH on anything below about 14.3, which is FAR more than lean enough to melt your cossie engine.


So if you want a piece of shite guage that tell you "FULLY RICH" when you are dangerously lean then carry on, if you want something useful, buy a wideband.
