Fuel injector Constant

[Ward]

This is the math from several of my type $32 calib's for the Y car.

Snce you didn't spec the calib's, they may in fact have different injectors,
in any case other elements in the calibration could accomidate the relitivly
small differances you report.

GM did replace early Y car injectors due to high failure rates, (leakage).


LC3D6:  FDB 441     ;  Prod of Inj Flow rate
                    ;  0.3445 Sec/Grm
                    ;  Num = (sec/grm * 256) * 5
                    ;  DOUBLE FIRE

LC3D8:  FDB 882     ;  Prod of Inj Flow rate
                    ;  0.3445 Sec/Grm
                    ;  Num = (sec/grm * 256) * 10
                    ;  SINGLE FIRE
                    ; 0.344/sec/g, 2.902 g/sec * 3.6 =                     ;
10.448 kg/hr, (23#)
