    A CAT ID only shows information that is already in an ECM. So it is no more or less accurate than your ECM.

    You can make corrections to adjust the mpg and get it close, so in a word, no. Ecm's aren't to be trusted either. The only way to really know mpg in any vehicle is to use a calculater and the tripodometer from what I've seen.
