Hello,
Im testing the "OBD2 adapter" and with the "rpm_led_uart" sketch work ok.
I added other Pid as PID_ENGINE_LOAD, PID_INTAKE_MAP , that reads the data, but if i add some PID´s as ENGINE_TORQUE_DEMANDED, PID_FUEL_PRESSURE, don´t it read and the reading the other PID is slows.

Is it possible that "OBD2 adapter" can´t read all Pid's in all cars?

Thank you very much

That's mostly because your car is not responding to requests of those PIDs.

Hello, si it means that we cannot get those PIDs even if they are standard ? Is there a way to find it ? I need the torque
cheers
