sounds like the aldl datastream definition you're using is incorrect. which are you using?

There should be one included when installing TunerPro RT. Does taht one work correctly? If not, check the TPS item in the definition and make sure its defined correctly.

what should it be its divide(factor/x)+offset
factor 51.0

To display voltage, it should be set to multiply and the factor should be 0.019608.
