Shortly after I got the Pro-Flo
fuel injection setup on the car I could see that I needed, and wanted,
a better means of observing the status of how the engine was running closed
loop. The supplied controller had a bi-color LED that you could get
a general idea if the engine was lean or rich. This controller is
a neat and handy device but it is a little inconvenient to observe while
you are driving. What I did was build a LED dot/bar graph that I
mounted in the dropped steering wheel support. These 7 LED are easily
seen without taking your eyes far from the road. I added a little
extra circuitry to dim the LEDs at night when the headlights are turned
on.
