Engine : 1.5L
Fuel cut off: 17
Anything else I should be tweaking?

Set the fill calibration back to 0%. When you raise it it lowers the MPG reading artificially. Ps0nq had good advice to leave it at factory settings. It won't always be exact but mine comes within 0.5mpg of what I calculate when I fill to full based on car's trip ODO.
