Maximum fuelinjector capacity?

Does anybody know the max. cc/min. @ psi/bar for the standard injectors?
The reason for this is that i need to know this first because i have to make a map for a aftermarket ECU with 2 (lambda) O2 sensors.

aftermarket ECU with 2 (lambda) O2 sensors.

Meaning an aftermarket ECU w input for two sensors?

What brand ECU are you trying to fit?

Yes, with two O2 sensors one for each cilinder.
If I know the max. cc/min @ psi/bar its possible to calculate fuel injection pulse time needed for air/fuel ratio @ rpm.
The ECU is Australian brand - the thing is that they don't have experience with Ducati's and O2 sensors.
If I can make a map with approximate settings the sensors wil do the rest when driving your bike.
You get a bike that runs smooth and good from a cold to hot engine and always running with the almost perfect air/fuel mixture.
The O2 sensors are pre-heated wide band types. Bosch LS03.

And the brand is?

If you want to sell the FIM Memory Board & flshchip I`ll buy it:

DOn't know if this helps, but according to cagiva905, the flow of the Weber IW-031 injector is 270 cc/min at 3bar. I assume that is static full flow rating, at 80% max duty, and it coincides about right for hp rating of the 907ie from formulas I have seen. (see Marren injectors website and RC injectors website) I wonder if you could bump that flow rating up a little with a different injector and gain any power?

Good luck, keep us posted.
