Hi,
We did a test of following easy script on car that runs on petrol and CNG. It is original bi-fuel car produced by the car company ( CNG is not added afterwards).
`import obd obd.logger.setLevel(obd.logging.DEBUG)
ports = obd.scan_serial() print(ports)
connection = obd.OBD()
print("starting dual fuel")
c = obd.commands.FUEL_TYPE feedbackString = connection.query(c) print(feedbackString[0].data) `
