Can the EManage link directly to an WB o2 sensor? Because WB sensors all require a specialized controll box that is often specific to the model of WB sensor in stalled. LIke the LC1 kit. Then, these control boxes often also output a 0-5v signal that can be used by a piggyback for auto-tuning and such. I don't own an EMU so I'm only guessing here, but check the inputs the EMU is expecting. If it's just a single 0-5v signal, then you will indeed need a full WB kit.
