Adding O2 senors

Ok, I have did searches in these forums, as well as others, and I have yet to find an answer to this.

I have a 2006 FLHX-I, for those of us that prefer the names, it's a fuel injected 2006 Street Glide.

A friend of mine is now doing tts tuning, which involves removing any piggy back programmers (power commander, ect...) and he then rewrites my ECM. I was sorta skeptical at first, but then let him do it. WOW! over 20% more hp and torque over what the PC3 and a dyno tune got me.

Anyhow, this is thread is not about what he did, but rather what I want.

My bike came without O2 sensors. If I had O2 sensors, he says that the ECM would constantly adjust to air temp, humidity, and other weather/atmospheric conditions; but since I don't have O2 sensors, I am still only running the one map or tune.

SO...how do I got about adding O2 sensors? Is it as easy as getting an ECM from a bike with O2 sensors that will still plug into my wiring harness? I do believe they had some '06 SG fuel injected with O2 sensors in California, no?

Any help is most appreciated.
 
You do not need O2 sensors. The ECM should be using the MAP (Manifold Absolute Pressure) sensor.

From the TTS manual:
