It's not necessary, but IMO it's worth checking that they are not far off. There are areas of the MAF scale where both DI and PI are in use. The ECU does not differentiate when applying trims so if the PI is giving a +2% error but the DI is giving -1% the STFT will fluctuate, as will the LTFT depending on how much of each is in use. Obviously this will have an impact on MAF scaling.

Thanks for the explanation of the smoothing, it's not explained as well in the useage tab. The fact that the MAF scale doesn't appear unless you click on the tab is misleading IMO, the scale should be there in all views. Maybe a button to open the scale in a separate window?
