Smartcraft Speedometer

[agreico]

My speedomter has been acting wierd lately. At times it registers speed, however other times it jumps to 70 MPH and holds there. When I start the engines, it jumps to 70 MPH??? Any ideas??

Mine started acting weird kind of like that right before the Pitot Sensor died. Have you gotten any Pitot sensor Smartcraft Alarms (Beeps)?
