I've been reading up on the technology but so far it's all been theory. Care to enlighten on a noob?

The wideband's 5V output can be connected to the OEM ecu by using the rear o2 harness. This at the very least gives the your ECU the abilitiy to read and log actual wideband afr, not sure what capabilities this extends to the tuner beyond that point though. @
