Injector duty cycle won't matter what injectors you have, it should be accurate. I believe it's based on what percentage of the time they're on, not a factor of how much they're actually flowing.

If you're just using an AFC or something like that, you can't really adjust the closed loop A/F ratio, the ECU will shoot for 14.7 automatically and adjust fuel trims to reach that.

Edit: looks like Shane beat me to it.
