Obd fusion app

Does anyone use this on the iPhone platform? I have a question on the data input when putting in vehical information. As far as volumetric efficiency and Brake specific fuel consumption....?


Has anyone accurately logged this in? Where are the nerds lol... not too book smart here.

Don't know the specifics for the engine but volumetric efficiency should be about 102% unless that's supposed to be an instantaneous value. Brake specific fuel consumption could be .45 but is probably closer to .55 lb fuel per hp.

Those items are only used to guess-a-mate your fuel economy, so don't worry about being exact.

Since the BFSC and VE very depending engine load and RPM, a single value is almost meaningless.

Enjoy the app, it is great!
