With an open loop, can I still tune the bike to make more hp and torque, idle correctly, good throttle tip in, etc?

I'm also worried (naturally) about operating that part of the ECU in an open loop and having a lean out at certain rpms, load, conditions, etc. How critical is the 02 Sensor to the whole picture?
