Fluctuating between what? If you dont have a scope, how about a signal generator? Does the speedo work in acctuators? Do you have a speed reading in live data in ecu or BSI or instruments? Where have I left my glasses today?

You say no speedo on dash ? is that in live data or using actuators? You need some proper kit I think!
