Yah, I can go for the just enter/adjust the flow rate and the vss tics per mile too and just a reset on the tank. If the users can solder together an arduino, they can figure those parameters out and make adjustments accordingly by looking at the tank gallons before resetting, and maybe an online database to look up the values for common vehicles.

So we would have:

Screens:
Main Screens (using right button to switch screens, left button goes in
reverse order, select only works on resets and injector/speed adjust):
Inst MPG 0000.0
Curr MPG 0000.0

Inst MPG 0000.0
Tank MPG 0000.0

Inst MPG 0000.0
Curr Miles 00000

Inst MPG 0000.0
Curr Gallons 000

Inst MPG 0000.0
Current Reset

Inst MPG 0000.0
Tank Miles 00000

Inst MPG 0000.0
Tank Gallons 000

Inst MPG 0000.0
Tank Reset

Inst MPG 0000.0
Speed Adjust

Inst MPG 0000.0
Injector Adjust

So that is 10 items to scroll through on the main screen, with a scroll back button that is probably fine.

Speed Adjust screen (scroll buttons to adjust +-1 , maybe hold for +- 10 every .3 seconds?)
VSS Tics/Mile?
3200

Injector Adjust screen (scroll buttons to adjust +-.1 , maybe hold for +- 1.0 every .3 seconds?)
Max Gals/Hr?
20.1


I'm not sure if 1/10 a gallon/hour will be fine enough resolution. But we can go with it for now.
