I have a GRT EIS 4000 and a red cube fuel flow meter. The version K instructions say to set the calibration at 200 and then adjust as you measure actual fuel consumption. The instructions with the red cube say to set it at 83 and adjust according to your fuel consumption. At 200, it is definitely reading way higher than the actual fuel flow. At 83, it seems to be substantially lower than I would expect it to be.
What calibration settings have others found?
