I fiddled with my FQ based setup and I must say.. not all that bad.
As you can adjust the FQ with a pot meter at the back it tried centering aound each plate.
50-100-200 cfm.
I got the decent results using the 100 and 200 cfm plate and setting it slightly high for the 100 and slightly low for the 200 (which is only getting 16,5 ' depression and is then corrected).
When you start with the 50 CFM plate the numbers are very low. Using the 100 or 200 it is a lot better over a wide range just the low range (50CFM) flow reading are still too high (53.5 CFM) but I can live with that.
100 reads as 100.6 and 200 as 199.6.
The orifice in a pipe that comes with a FQ now reads 83,2 (it should read 80.9, but with the depression connected to the 2D takeoff in the pipe it reads 80.0).
I will ask Audie tech if they are willing to add a calibration section to the software/hardware.
