Hi David,
 
Thanks for asking.  I have just finished a=20 contraption that will permit me  to "print" solder paste on a PC = board=20 designed around Surface Mount Components (read smaller than the eye can = see -=20 almost).

Two Different = Instruments
 
I decided to come up with two = versions. 
 
Simple/Inexpensive
 
One is a simply Fuel Flow and Air/Fuel ratio = (LED)=20 indicator in a package small enough to fit in the 2 1/4" instrument = hole. =20 But, that is all the information it will provide - Fuel Flow and = Air/Fuel=20 Ratio.  This will be the cheaper version.  This will have a 10 = segment=20 LED bargraph for the Air/Fuel Ratio and a 3.5 digit LCD readout for the = Fuel=20 Flow.

The full-up EFI System Monitor  will = provide on the=20 colored display the following:
 
1.  Fuel Flow (GPH)
2.  Fuel Used
3.  Fuel Remaining
4.  Time Remaining (at current burn=20 rate)
5.  RPM
6.  Power (Calculated based on fuel flow=20 rate)
7.  Switch Tank Alarm
8.  Low Fuel Alarm
9.  Air/Fuel Ratio Indicator
10.  Semi-Automatic Self Calibration of = system to=20 your injectors
11.  O2 Voltage and Adjustment=20 Capability
12.  Ec2 Interface - this will = include
      a.  Function = to obtain=20 the Fuel Map and Engine parameters from the EC2
      b.  = Capability to See=20 and Adjust the EC2 Fuel Map (only one bin at a time - no mass =    =20             =    =20             = change)
      c.  = Capability to See=20 and Adjust the ignition Timing
 
      These are the = only two EC2=20 functions that I intend to ever  provide.  The rest of the EC2 = modes=20 will require the normal EC2 program button adjustment = procedures.
 
      The fuel map will = be=20 displayed as a bar graph
      The Ignition = display will=20 show you the number of degrees and whether in=20 "Advance"or       "Retarded".  You = will be=20 able to adjust this parameter.
 
So far, I have the new OLED display working on = my=20 development board and the color capability really enhances the = information=20 display.  I have the new board for the new display, but need to get = my oven=20 before I can get one completed and working.

One of the items that you often don't think = about but=20 which takes almost as much effort and appreciable cost is  = control=20 panel/instrument case - cost more than you might think.
