The stock ECU is capable of controlling very high flowing injectors. I have 800cc injectors in my car right now. It calculates it's fueling based on an injector scalar value. For a Stock WRX it is 6442. But the way this # is embedded into the ECU is a little weird. I guess engineers STILL go to great lengths to save space in their programs. There's something about the way a 2 byte hexadecimal is coverted into decimal form. There are reverse type ones etc.....
