Reason I ask about this topic is bacause I want fuel economy from CLF and power from OLF when i step on it.

Thanks
You can use either sensor for closed loop fuel control. Re-read my post which explains what parameters you can use "closed loop" for given the sensor you choose to utilize. With the OEM sensor your only choice is 14.7:1 AFR but with the WB you can choose whatever AFR you prefer at a given load and rpm.

Thanks,
