[QUOTE=MetroMPG;88057] ... trying to calibrate the SG to your actual tank results... QUOTE]
I am getting these wierd fillup compensation.
The SG read 35.5 Litres used, whereas tank fillup was 43.4, and I upward adjust the fillup compensation at every tankup. And over the last 7-10 fillups the compensation has risen to 173%. It is going to rise even more at the next fill, I am sure.
What I am surprised at, is the consistent under-reporting of fuel consumption.
