Closed Loop with One O2 Sensor in Downpipe of Turbo.

In this episode, we wire in one narrowband O2 sensor in the downpipe of our LS turbo, and set up HP Tuners to run in closed loop operation on only one O2 sensor. Normally two sensors are required for closed loop operation but if you split the signal you can wire one sensor to both channels and get it to work. Perfect for your LS swap or LS turbo project if you're running the stock P01/0411 ECM. Should also work on P59 ECM's and possibly on Gen 4 stuff as well, but I haven't tested it on any other setup but my own.
