with one equation?
How are you imagine to control several indicators with one equation? then all the indicators should lit/go off at the same time?

If you want to get any indicator from your dashboard, you will need to have PIDs for your car's "Body electric"-"Dashboard" control unit. No, there are no standards for that kind of information - read forums for your car, search for custom PIDs there.

I meant plural. I drive a Honda and PIDs are top secret information for whatever reason.

Hi!

You can do this using DBC files and hybrid mode (which is automatic if you have a DBC file loaded and are using a CANBUS vehicle)

For example, there's a load of honda DBC files on the internet (basially search google for 'honda dbc') and then you can import the DBC files in using the PID management function in Torque - for example there's a load of dbc files here: https://github.com/commaai/opendbc

If you want to only pull information via DBC files (basically RAW CANBUS messages), then you can set the protocol (in the vehicle profile) to DBC only and then you basically get the data as fast as the adapter can stream it (we're talking in some cases of 300+ sensors/sec). Hybrid mode is adequate for most people though and gives you both DBC and normal OBD sensors at the same time (at a slower update rate)

Hey cool, thank you very much.
