Gauges & Dashboards
There are two types of LOAD specified in SAE J1979
One is CALCULATED LOAD VALUE and the other is ABSOLUTE LOAD VALUE.

amount of technology companies are willing to throw at your car’s dashboard is amazing (well, maybe not your car — after all, you’re still driving a ’76 Gremlin). Taking things up a notch, the folks at Fraunhofer have developed a dash that displays your location and the surrounding area in 3D, in real time. The system uses cameras to keep track of the location of your eyes, so the depth imaging effect can be achieved without using those funny glasses. In addition to the GPS, the dashboard only displays the information that is most relevant to the driver at any time — fuel gauge, tire pressure, route information or the title of the song can be displayed, depending on user preferences. It’s only a prototype at this point — be sure to check it out when you hit CeBIT in Hanover this March.
Several months ago I started to learn OBD-II programming and wrote a small utility to retrieve live data from my Scirocco’s OBD-II port. Since then I’ve improved my utility and made a graphic virtual dashboard on a tablet PC. Here is the video shot as a demo. The displayed data includes speed, RPM, engine load and throttle position. Of course a lot more data can be retrieved through OBD-II port and I planned to make several multiple screens showing different combinations of data to the virtual dashboard. Also I planned to add data logging and drag testing features.
FIELD OF THE INVENTION
The present invention relates to estimating mass air flow through a throttle of a vehicle, and more particularly to estimating mass air flow based on manifold absolute pressure.

Rev is an application for the iPhone and iPod Touch that monitors, displays, and records real-time vehicle data. By communicating directly with your vehicle’s ECU via its OBD-II port, Rev is the first iPhone and iPod touch application to give you complete access to everything you want to know about your vehicle.
