Oil Contaminant Separator (OCS) Orientation: The Official Word

I'm not sure about motorcycle EFI's but back in the day when I was a wrench, car injections systems were only in open loop in "choke mode" and the ECM would function is set, mapped parameters. Once they heated up to operating temp, they switched to closed loop and stayed there allowing the O2 sensor and map/baro or MAF sensors to do their jobs and adjust air/fuel ration constantly through block learn and integrator in your ECM. If this is the case here, the O2 sensor would sniff the extra fuel being recycled and shorten the injector pulse width slightly to keep the air-fuel ratio as close to 14.7/1 as possible.
If this injection system works like that, I have no idea..........
