Note 4 - Speed
The PWC speed sensor is wired directly to the dashboard. To acquire this
information, a separate wire is required from the factory harness to M400
Marine ECU pin Dig1 (B8). The supplied Base Map includes a speed
calibration which can be enabled if this sensor is wired.
For more accurate speed measurements, MoTeC recommends the use of a
GPS system.
MoTeC's 5 Hz GPS-G1 (#41300) can be wired directly into the EC
receive port.
