    Just installed the RC Calibrator in my 21'. Has anyone else had an issue with the Miles to empty being wildly inaccurate? Just topped off the gas tank and it says 605 miles to empty. I drove it for about 45 minutes this morning and it doesn't seem to be getting any more accurate...Speedo is now dead on with GPS though after a slight tweak to the settings.

    Did you unhook battery prior to install? If so, then it should eventually recalibrate

    Drive it for a bit. It’ll square up after a tank or so. It likely got confused.
