Change "Custom" Screen?
 

I think I have it figured out, but I want to check in case I missed something. I want to adjust the "Custom" screen to display like this:

Do do so, I change


to be
Is that correct? Are the stats called "Current" for "current trip"?

This might do it:

void doDisplayCustom(){displayTripCombo('M','G',instant mpg(),'M',tank.mpg(),'G','H',instantgph(),'G',tank .gallons());}

The order of the values is Upper Left, Upper Right, Lower Left, Lower Right. There's only room on the display for a single letter label for the two right hand values.

I assume here that you want the instant information on the left and the tank information on the right. So, the 2 right hand values will be reset by pressing the left & middle buttons simultaneously. If you want the current trip instead of the tank, substitute current.mpg() and current.gallons().

FYI, tank.idleGallons() will give you the number of gallons burned at zero mph for the tank. You might want tank.gallons()

Instant I'd like on top, and Gallons on bottom. I didn't see tank.gallons when I was glancing over it at work - thanks for that. My 'guino display went blank on me on the way home today, so bust on the new tank of gas. I shut the car door, and an arrow "blipped" on the display in the left char on the top row, and then the display went blank. backlight still went up/down, but that's all I could do. So now that calibration is moot for this tank of gas, I unplugged it and will re-flash the code.
