OBD2 is a generic protocol. Not all sensors will report correctly. You should see the values I get in my Fiat! Load is basically a random number generator so I've taken to accelerating via ignition advance - even then -50 us about the sweet spot!

People put way too much stock into OBD2 consumption figures, particularly in city use. You really can't expect much better than +/-5%. That's the limitation of measuring air rather than fuel.
