Great video, really helpful.
I'm just not sure how you come up with 9.0 for Req_Fuel... I have similar injectors, they are 440CC Ford although they are low impedance... when I enter my engine characteristics of 2800CC, 6 cylinders, 440CC injectors, and 14.7 stochiometric, It gives me 7.1?
I am using MS3, maybe it is a different formula?
