2005 rsx o2 sensor(s)

I think I have made a mistake in something I've told a few people. I thought I had saw here on the hondata forums that the primary sensor on the 05+ rsx was not a wideband anymore. Is this the case? I have told a few people that and somone asked where I had got the information and I couldn't find it at all -- so I'm wondering if I just missread something at some point.

How many o2 sensors does the 2005 have -- is it just one, or are there two (I imagine 2, but a parts catalog I saw only listed one sensor).

Is there a wideband o2 sensor on the 2005+ rsx.

I realize that it won't work with the 02-04 ecu, and is likely not compatible with anything, but I just wanted to know if the sensor itself, from the factory, that the ecu uses, was a wideband.

The 05 has 2 sensors just liek the 04, but the primary is a different type and is not compatible with the 04 ECU. The 05 sensor will generate errors on the 04 ecu and appears to read a very narrow a/f range. It is still a wideband, but not wide enough.

Are there some specs on it anywhere?
