the only way it can loose the calibration is through a bad programming error

one set of values i have is
fuel resistance 60 65 100 120 140 160 175 195 210 235
fuel litres X 2 150 132 122 112 102 96 86 74 50 20

what are you using to program it?

The fuel Guage sender is a simple variable resistor in VY its hard wired to the dash
