If you can get airflow (mass) from the OBD2 port, you should be able to do a simple instant fuel economy calculation based the stoichiometric air fuel ratio of 14.7 to 1. Factor in your speed, and you're good to go.

The SuperMID works by using a (user-programmed) volume for the fuel injector. It counts fuel injector pulses per distance traveled and bases the calculations on that.
