What steveo said. If the MSB of the 16-bit Word is 2 and the LSB of the 16-bit word is 200, then the complete value of the 16-bit word is 712. Plugging 712 into the MAF conversion equation from earlier, it comes out to 5.5625 gm/s at idle. At hot idle my '95 Corvette hovers around 7 gm/s, for comparison.
