When I built the Duty Cycle Fuel Flow meter, I also added a LED light bar to give me a air/fuel ratio indication from an installed narrow band O2 sensor.  So the LCD display and LED bar were all designed to fit within a 2 1/4” dia format.  Here is a shot of the PCB board I used.  The LDC display and LED bar were mounted on the front (opposite) side of the board shown

Thanks Andrew, but the sly sods want 2 flow meters as well for the low price of  $1200 All up plus fittings, say $1500.  Neil.

Mgl say they are now open source, so completely configurable if your so inclined. or just use as is. worked for me.

Neil, lots of options out there, both Tracy's & Ed's engine monitors will do what you want. MGL Vega single FF-4 would be a good option also.

Gents,  Is anyone aware of a fuel consumption  gauge that will give fuel consumption in real time?  I can get one that has two flow meters but that makes installation complicated and not really cost effective.  I am looking for something that works off the injectors.  As usual it has to be "tweaked" with actual fuel usage.  Did not Tracy have such a system?  Neil.
