$8F INJ flow rate per single fire

I have installed 39# injectors and using $8F. I changed the INJ flow rate #/hr, but do I need to change the "INJ flow rate per single fire". its located at 65E hex

I adjusted the bpc vs egr as well and the car is driving good. I just want to make sure the ECM has all the correct settings. thanks

In most cases the single and double should show the same number (to match the actual injector flow rate).

Sorry, yes, you should adjust the injector constant to match the injector size that you installed. The fuel trim (BLM) will tell you, ultimately, what it should be set to. If it's rich across the board, increase the injector constant. If it's rich in certain ranges only, adjust the fuel tables in those ranges.
