auto tune 02 sensor

[andyferd_imp]

Hi Outback. I'm running the PCV/autotune with the delkevic headers and mid pipe. In order to use the autotune-supplied O2 sensor you have to grind off the existing O2 bung on the Delkevic mid pipe and weld on a new bung since they are different sizes (The autotune O2 sensor is bigger as I recall). I welded the new bung to the same spot on the midpipe and didn't run into any position issues when installing the new O2 sensor. I don't remember exactly where I routed the cable but I followed the original O2 sensor routing to get to under the seat where I mounted the PCV/autotune.
