Using the 5V ref from the Dash 2 and a 100 ohm resistor I get 0.15V for full and 1.15V for empty. It's pretty much linear in between these values
I enter the data into the table to create an equation for the sensor and upload that to the Dash

The dash then reads 60 for empty and 120 for full.
I've done the same for the single wire sensor option and get the same result.
It's as if the reading is 2x30 (tank capacity) off where it should be for empty and 3x30 off for full. Is it a maths problem?
Any help greatly appreciated
