I built my RV7 using the Van's resistive fuel level sending units, which are connected to a GRT Avionics EIS 4000. GRT has a set of formulas that you are supposed to use for calculating two parameters: scale factor and offset. I came up with values for those parameters, entered them into the EIS, and got bogus results. I then found an on-line calculator on the GRT site, used it, came up with totally different results (which I entered into the EIS), and again got bogus results.
If any of you have mated the GRT Avionics EIS 4000 to Van's fuel level sending units, please let me know what values you used for scale factor and offset (assuming they worked).
Thank you!
