Hyundai Elantra CN7 OBD2 PIDs

This is a list of OBD2 PIDs supported by a Hyundai Elantra CN7 MY2023 with the 1.6 MPI Smartstream engine sold in Europe.

The vehicle has been built in the Ulsan factory in South Korea so I'm assuming that these should also work for the 1.6 MPI and 1.6 LPI engine variants sold over there.

These have been tested using the following setup:

Standard PIDs (Service 01)

Please refer to https://en.wikipedia.org/wiki/OBD-II_PIDs for more details on these and the equations used for each one.

Custom PIDs

These PIDs are setup to be used via the Torque Pro app and therefore some of the formulas are based on the Torque Wiki.

Torque Pro Dashboards

This repo also includes two Torque Pro dashboard setups based on the above list of PIDs that could be easily imported into the app:

v1

v2

Please note that the contents of the theme folder also need to be amended for each dashboard to work.
