Default why are rdx injectors still refered to as 410cc?

where is that number coming from?

according to this page they are nowhere near 410cc at stock(55psi) pressure more like 500cc

but most people keep setting the injector size to 410cc

Most injectors are rated at 43.5 psi, not 55.

check the 43.5 psi its still not 410cc
its close to 440cc

the stock pressure for rdx is 55psi not 43.5

you will find variances between many advertised injector rates vs actual flow.

are all the following linear?
flow from increasing fuel pressure
injector size in Neptune settings from smaller to bigger injectors
and overall trim

if I increase pressure and increase injector size to what its flowed at in the above chart(500cc at 55psi) and decrease overall fuel trim to match the idle afr will the injector still flow same everywhere else?

you understand what the difference is between stock Honda injectors and rdx injectors?

what youre saying is. similar to b16 b18 b20 whats the difference...

I'm just saying, your argument is retarded.

The flow volume is skewed on ALL injectors.

tard

im asking why do we even need the flow number if it doesn't matter in the tuning sorftware since a lot of people use different settings for injector size which are not even close to what they are rated at.

or does the injector size setting affect sometning in a different way than overall fuel trim

Why do people call all 6th gen Civics EKs when they aren't? Sounds like the same thing here.

Most of the newer software uses the what injectors they are and what pressure your running to set the correct deadtimes or battery offsets or whatever they call them in there programs.

so the injector size is linear increase/decrease just like final multiplier?
