Or???

Or we can go completely spartan, no buttons, one screen, reprogram the device to change the injector flow rate and vss tics per mile, hit the reset button to reset the tank:

the screen would look like:
Code:
I000.00  C000.00
T0000.00m 00.00g
Upper left is instant MPG
Upper right is current MPG (resets after 15 minutes of inactivity)
Bottom row is Tank Miles and Tank Gallons.

No eeprom, no buttons, no menus, etc.

To calibrate, you jot down the mileage at a fillup and note the change in mileage and the gallons used at the next fillup, go into the program and tweak the vsspulsespermile and injectorflowrate up or down by the percentage that your actual mileage and or fuel use is off.
Then reload the program on the freeduino.


Ok, lets start there anyway.
