Just need some help to see if my understanding of the IFR table and how to scale for new injectors is correct.

Fuel Injectors:
'00 Stock Fuel Inectors - 26.6 lb/hr @ 400 kPa
Delphi 32 lb/hr injectors - 31.6 lb/hr @ 300 kPa = 36.5 lb/hr @ 400 kPa
400 kPa difference (delphi over stock) = 137.22%

IFR table:
Look up table for the PCM to determine the injector flow rate (grams per second) at a given MAP (kPa).

Scaling:
To properly scale the IFR table, I need to multily the stock numbers by 1.3722

Is my understanding correct?

horist

31.6 @ 3 bar, 400kpa/300kpa = 1.33^.5 = 1.155 so 31.6@3bar is 36.49@4 bar
stock injectors are 26.6, 36.49/26.6 = 1.372

yup your numbers checkout, scale your stock table by 137.2%
