Hi Kelly
 
Here are the current EFI Monitor = Functions
 
Menu Screen to permit selecting:
 
    1.  Fuel=20 Status    2. Fuel Adjustment = (adding or=20 otherwise adjusting fuel)
   
    3. =20 Calibration    4=20 Operation
 
Pressing button 1 (Fuel Status) = provides=20 current fuel factor info on 5 items:
 
   1. Fuel = Remaining=20         2. Fuel Loaded = (if you=20 have just loaded fuel)
  
    3. Low Fuel=20 Alarm        4. = Notification=20 Alarm (Switch=20 tanks)         &nbs= p;   5.   Fuel_Total=20 (Fuel Remaining + Fuel Loaded)
 
if you want to change any of those fuel = factors=20 button 2 (Fuel Adjustment) permits any of those fuel factor=20 values to be changed
 
If it appears the fuel remaining the system = has=20 calculated is sufficiently different and you have = confidence=20 the fuel remainder is incorrect, then you can have the system perform a=20 calibration.  If compares the fuel loaded with = what=20 it calculated should be the fuel remaining.  Any=20 difference (error) in its calculated fuel remaining and your input is = used to=20 adjust a constant in the program which should give a closer agreement = between=20 the fuel remaining the system has and the one you know = to be=20 correct.  A running average is used (current 8 samples, but I am = going to=20 reduce it to 4).
 
Also the calibration section permits you to = adjust the O2=20 sensor constant so that the indicator can be adjust for aging of the 02=20 sensor.
 
Once you are finished adjusting any fuel factors = or=20 calibrating then you can go into operation Button 4
 
Note: The system stores fuel remaining and any = changes you=20 may have made to alarm/notification values in EEPROM so when you start = up again=20 - it loads everything back into the program as you left = them.
 
There are 5 operational screens.
Screen1   =20     Screen2 =       =20             =20 Screen3   =20 Screen4          =20         = Screen4a    Screen=20 5
Fuel Flow     Time=20 Remaining        RPM   =20         A/F Indicator   =20      O2 Voltage        = Fuel=20 Status (5 fuel factors mentioned above)
Fuel Used    Fuel=20 Remaining        =20 Power        Fuel Flow  =20 Rpm
 
I intend to normally fly using screen = 4=20 as it has A/F indicator, Fuel Flow and RPM.  Screen1 and Screen2 = would=20 follow with screen 3 and screen 4a probably the least used.  But, = hey the=20 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=20 operation with two pushes of a button,  if you do not want to = change or=20 check anything.
 
The Notification Alarm is meant = to remind=20 you to switch fuel tanks (or some other fuel management thing).  It = sets=20 off a flashing red LED to get you attention with a message on the LCD = "SWITCH=20 TANKS".  It is set based on Fuel Used = . This=20 alarm can be turned off.
 
The Low Fuel alarm is just that = - current=20 when it goes on - it stays ON, the only way to disable it is to shut off = the=20 system and leave if off.  Its mean to remind you that you are down = to X=20 gallons and to find a pea patch quickly.  This alarm is based on=20 Fuel Remaining
 
That's about it.
