Reply after some time but maybe tell something more
Yes FKVA is 1,0625 not 1 because KVB is 371,72 not 386 but really injectors are mor like 394
and for 1,0625 x 371,72 we have ~`395
And for me if I take 395 as size when go from 3 bar to 4 bar fpr my KRKTE is 0,2% wrong so for me thats why constant are 1,0625 not 1
