in a closed loop operation.

You would need to have a wideband O2 sensor installed to use the E-Manage Autotune feature.

I'm currently wiring up an emanage ultimate and nowhere in the installation manual does it have any wires related to the O2. I understand the need for the wideband plugged into the serial input, but the O2 is still not handled by the emanage itself.

All i've been reading on the internet is that people are making/buying an o2 clamp. I'd imagine it's just a comparator or something feeding the lean voltage to the o2 once you're in boost, shouldn't be too hard to figure out how to make one.
