A MAF curve can't perfectly smooth by definition as it's made up of straight lines
However I'm not sure that having a not smooth curve is ideal, there are compensations to deal with the issues that cause "errors". There are many people who have "smooth" MAF curves that work fine, and don't forget that the MAF isn't just for fueling targets, it's used for most of the calculations in the ECU. I would suggest that this is where it being a nicer curve is beneficial. I'm sure (read know) you can hack a MAF scale up to get it to fuel right, but is this correct, or just quicker? I'd assume there's a reason the OE calibration is as it is.
Don't take what @
phrosty said personally as it's a valid point. Trusting your engine to a complete randomer on a forum is generally a bad idea.
