I have made a digital dash board for a pre-OBDII nissan car with a consult port. I created the software that reads from the car and displays the dash however I want. The dash runs on a raspberry pi 3 and shows live speed, RPM, and coolant temp right now. Later I want to add check engine codes and the ability to clear them. The raspberry pi reads directly from the car's ecu through a USB -> serial port -> consult port adapter and then displays the data on a touchscreen that is mounted over my dash.
Nice project. Is there any way to get fuel consumption from ECU? I want to calculate roughly how much fuel do I use from an instant to another and then paying for only that amount of fuel, as the car is shared. Which other parameters can be read from the OBD? Thank you.
