Error to Add New PID to OBD-II Uart Adapter
Posted: Sat Sep 24, 2016 4:57 pm
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!!
