Does anyone know of any good Air Fuel Ratio Gauges? Need to have the following:

60mm Diameter
Digital numeric display in AFR and Lambda values
Black face with red backlight

Thanks.

why not read the values direct off the motec? it will be more accurate then any guage!

a proper one or a narrow band toy?

Proper ones need a wideband sensor & controller like these:

2j1/9 wideband control unit : http://wbo2.com/2j/default.htm

Techedge LA1 display (it's 52mm + it's bezel) : http://wbo2.com/la1/default.htm

The tech edge gauges use the digital stream direct from the controller.

Perhaps you can drive the display off the motec alone? I don't know if it's possible.

This is what I intend to do. When tuning I read it off the laptop screen but I'd like to have AFR within easy view for when I don't have my laptop on.

That display looks nice, unfortunately 52mm won't fit in the 60mm hole without having to make up a plate or adaptor of some sort.

Actually, thinking about it and what Stace said about reading it straight from the ECU, it shouldn't be too hard to make up a simple 3 digit LED display to fit into a hollowed out gauge and then have that display the AFR - maybe even the Jaycar O2 display kit might do the trick....

just define lambda as a lookup into another aux output table, scale it onto any 0-5v/0-12v guage
