"Because my unit solves an actual conversion equation instead of referencing a lookup table, it's not subject to error from interpolation. It was tested on a superflow flowbench to be incredibly accurate all the way up to the maximum flow rating of about 850 CFM. (much more so than a single MAF alone, especially at high flow) The SAFC is a lookup table based device. I have one in my hands for testing and will share the results as they become available."
