injector ecu flashing?

hey guys,

so i am looking for some direct injectors to my OEM block. my original DI are in my built block now and i'll be grabbing a used set on ebay. But i can only find ones that are marked with a different number than my original ones, which is 2.

i read on fb that you need to reflash the injector ecu when you change your DI numbers. But nothing on how to do this. Is this something only the dealer can do?

OR will this even matter as long as I have the same numbers match on the direct injectors?

there is no need to alter the DI injector ecu they are all same

all you need is a set of four DI injectors with same numbers on them

they can all be 1,2,3 but you need a set of say all 1 or all 2 or all 3

just dont mix numbers in a set and your good to go
