While it can be accurate for external factors like aero drag, it cannot give results for things that affect the quality of combustion, like lean burn and acetone. Because it is an air meter, it can't tell you that you traveled the same distance using less fuel. If you used the same amount of air during that trip, it will report no difference.
What if you divide the MAF value by lambda (assuming you have an accurate lambda value)?
