Do you have any idea how to scale for a larger MAF?
It was like 10 years ago I worked with 4.4 so I honestly don't remember, but something tells me that I never figured out a way to rescale any flow vs voltage. Instead (if I remember correctly) I rescaled flow vs load using the datasheet of both MAF-sensors to figure out how flow, load (and voltage) corrsponded between stock MAF sensor and the larger one I was trying to fit.
