    If have run hundreds of hours with both pumps and hundreds with just one. In all cases the actual burn is more than that reported by the Rotax ECU. Fuel quantity gauges in GA airplanes are notoriously inaccurate. Fuel burned totalizers based on fuel flow can and should be far more accurate. If Rotax is unable or unwilling to correct the issue themselves, they should at least drop their prohibition on avionics companies allowing end users to make adjustments/corrections. Pilots with carbureted Rotax engines can make FF adjustments/corrections via K-factor. Why not allow pilots with iS engines the same ability?
