2008 Hyundai Accent\Verna CRDi (turbo diesel) OBD CAN bus data display on 20x4 LCD using Arduino Mega 2560 & Freematics OBD UART adapter.



Displayed parameters are:

Left side
Engine rpm
Fuel Rail Pressure in kpsi
Boost in psi
Voltage at ECU

Right side
Intake Air temperature in celsius
Coolant water temperature in celsius
Load in %
Commanded EGR in %

A modified version of test_obd_uart code to 'switch on' led based on rpm.

RPM based dual stage LED shift light. The LED shift light is programmed to 'blink' between 2800-3800rpm, more than 3800rpm it remains 'on' -

Nice, I also use to own a Hyundai Accent. I have now upgraded to the Hyundai Creta> It is a compact SUV car from Hyundai.
