I am using Expedition (v. 11.0.14) to send calibrated BSP to mast displays. The system is based on NMEA2000, connected through an Actisense to the PC. Masthead displays are Garmins, the rest of hardware is B&G. Numbers are sent through one of the custom channels. BSP is ticked in the dialog box "Expedition calibrations" and the matrix filled in with reasonable numbers. The manual says Exp will add these numbers to the uncalibrated BSP. This it did last year, but this year the numbers on the mast displays are silly, showing 18 knots when the boat is doing 6. I literally have done nothing but update Exp.

What am I doing wrong?
