Hi,

I’m using OBDLink SX with Audi A4 B6. When using RealDash I only have a limited ammount of data available for input on the dash.

For example:  
The car’s ECU outputs brake oil pressure.  
In RealDash I only have “Brake pedal position” option available.

How can I find all the other ECU datafeeds with OBDLink SX ?

Three (quite difficult) steps:

1. Find your vehicle specific PID values along required ATSH headers.
2. Make a custom OBD2 connection XML file that includes commands specific to your vehicle. See docs here: [RealDash-extras/OBD2 at master · janimm/RealDash-extras (github.com)](https://github.com/janimm/RealDash-extras/tree/master/OBD2)
3. Import your custom XML file into RealDash OBD2 connection settings.
