I had a dealer look at it on its first service and they implied that it just did what it was supposed to without setup. I am not sure that I believe that so keep an eye on the fuel filter anyway. If you get a sensible answer, please let me know.
As for the gauge calibration, that is only for the fuel tank level meter. The fuel used, l/mile, l/hr etc are all set up ready to go and do not rely on the gauge at all, as per your old engine. I tend to use the level as an indicator but brim the tank every once in a while and go on fuel used since last reset. I believe if a gauge and GPS are connected it will tell you a range in miles left in the tank. I really must get around to connecting this at some point.
