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

When you setup CLF, you setup the rpm ranges that it'll work in as well as manifold pressure. When you step on it, it'll swtich to OLF depending on your settings.

I would use the Hydra WB O2 to tune your Open Loop fuel maps, after you've got it all dialed in, then take it out and switch to using the rear O2 sensor for CLF. I would do it this way because WideBand O2 sensors are known to have much shorter lifespans compared to regular O2 sensors.
