I have a KA24DE running a Holset turbo, I am running a z32 MAF, blow-through and at about 6 psi of boost I am reading a reference signal form the MAF of 4.125 voltage. Why is the voltage so high? How should I go about adjusting the Voltage quantifier? I am running this in a s13.

That's probably normal I pull almost 4.1v at 8psi on my 9:5.1 SR20DE with T28 and TOMEI cams on my Z32 MAF

Ah ok thank, well thats good to know!

Also found out that the MAF obtains it values exponentially, so that explains the huge value jumps and then starts to gradually increase.

It is more than likely a copy Maf. A genuine one wont do that, we run most our Z32 blow though and there is no way it should be reading that high a only 6psi.

Mines is OEM Nissan original Z32 orange label MAF and those are my readings that coincide with his since im on a smaller turbo makes sense, and my car runs perfectly fine with zero indication of a MAF problem, the OP got it right I believe.
