It depends of the template you are using but i think the template and/or the mapping file are wrong.It already works. Only the rpm, the oil and water temperature and the tires show the values "9999" I do not know what it could be!
"Dash_universal" is intended for the two stock templates (2.8 and 3.4 delivered from simhub) if you used any other template (from the butonz pack for instance, make sure to copy the "ini" and hmistruct files into the nextiontemplate folder and to choose them from the settings.
