Hi Kelly
Here are the current EFI Monitor Functions
Menu Screen to permit selecting:
1. Fuel
Status 2. Fuel Adjustment (adding or
otherwise adjusting fuel)
3.
Calibration 4
Operation
Pressing button 1 (Fuel Status) provides
current fuel factor info on 5 items:
1. Fuel Remaining
2. Fuel Loaded (if you
have just loaded fuel)
3. Low Fuel
Alarm 4. Notification
Alarm (Switch
tanks) 5. Fuel_Total
(Fuel Remaining + Fuel Loaded)
if you want to change any of those fuel factors
button 2 (Fuel Adjustment) permits any of those fuel factor
values to be changed
If it appears the fuel remaining the system has
calculated is sufficiently different and you have confidence
the fuel remainder is incorrect, then you can have the system perform a
calibration. If compares the fuel loaded with what
it calculated should be the fuel remaining. Any
difference (error) in its calculated fuel remaining and your input is used to
adjust a constant in the program which should give a closer agreement between
the fuel remaining the system has and the one you know to be
correct. A running average is used (current 8 samples, but I am going to
reduce it to 4).
Also the calibration section permits you to adjust the O2
sensor constant so that the indicator can be adjust for aging of the 02
sensor.
Once you are finished adjusting any fuel factors or
calibrating then you can go into operation Button 4
Note: The system stores fuel remaining and any changes you
may have made to alarm/notification values in EEPROM so when you start up again
- it loads everything back into the program as you left them.
There are 5 operational screens.
Screen1
Screen2
Screen3
Screen4
Screen4a Screen
5
Fuel Flow Time
Remaining RPM
A/F Indicator
O2 Voltage Fuel
Status (5 fuel factors mentioned above)
Fuel Used Fuel
Remaining
Power Fuel Flow
Rpm
I intend to normally fly using screen 4
as it has A/F indicator, Fuel Flow and RPM. Screen1 and Screen2 would
follow with screen 3 and screen 4a probably the least used. But, hey the
info was available and easy to calculate so why not show it.
It is fairly easy to change this set up of
displays
You can actually go from system turn-on to
operation with two pushes of a button, if you do not want to change or
check anything.
The Notification Alarm is meant to remind
you to switch fuel tanks (or some other fuel management thing). It sets
off a flashing red LED to get you attention with a message on the LCD "SWITCH
TANKS". It is set based on Fuel Used . This
alarm can be turned off.
The Low Fuel alarm is just that - current
when it goes on - it stays ON, the only way to disable it is to shut off the
system and leave if off. Its mean to remind you that you are down to X
gallons and to find a pea patch quickly. This alarm is based on
Fuel Remaining
That's about it.

A few of you folks have seen my prototype
EFI Monitor in its various unfinished stages from software running on
a development board to my bare designed board. You may now
collect any bets you may have made {:>). Here are a few photos of
the completed system. Cosmetics could stand a bit of improvement, but
that will wait until later (much later). It is now (finally) ready to
be installed in the aircraft (Fits in standard 2 1/4" hole).
