If you have a Bluetooth OBD-II adapter and an Android device, you can get Torque Pro and get this addon for it that can read some Hyundai-specific data. It's not everything, but it will give you things like the transmission fluid temperature, transmission input shaft speed, some VVT information, etc. if it supports that on your car:

This addon for Torque will add the PIDs for Hyundai.
I don't know the specific PID, but it can be read with Torque Pro + Advance EX for Hyundai.
