Would it be possible to add cal slot position as a user defined gauge, the Link ecu can end this info over CAN if there’s a rotary switch fitted or can keypad with stepped button inputs.
If its on CAN, it can be added. You need to define this switch data in CAN XML file in order for RealDash to understand it.
See RealDash CAN XML specs here:

Ok thanks and got that working fine.
So next question 
Is it possible to get the software to convert that numerical value into a text message.
IE position 1=Low boost
Position 2=medium boost
Position 3=high boost
?
Yes, use the ‘enum’ attribute in the XML. See specs here:

Awesome,
