Vspd is that vehicle speed? Because if it is, mine flashes 0, 52, 79, 0, 63, 94, 0, ect... and the graph shows it maxing out and bottoming out in succession. It does this with the sensor disconnected too and when the car is running, not in acc or on position. Also my turn fuse and wiper fuse blow instantly. Anybody have the Vspd issue? I figure I have a open ground somewhere on the fuse issue. Related maybe?
