There are two stored parameters before the "# of cylinders" parameter.

The first is "P(Fuel)" and it can be in either psig *1000 or in Pa. The second is "P(Ref)" and it can also be in either psig *1000 or in Pa.

In the code I have attached at the beginning of this thread, I have both of those values set to 43500 psig * 1000, so that square root portion will evaluate to 1.

P(ref) should remain at 43500 psig * 1000, because that is the pressure that fuel injectors are normally flow-tested at, to get their flow ratings.

P(Fuel) is the fuel pressure of your vehicle, and should be set accordingly.
