S300 w/ h22a O2 Sensor problem

I have a problem with getting a s300 working for a H22a. I can datalog and read values just fine. My problem is that the o2 sensor only reads like 10:1 or 17.6:1 in the windows. Could this be a bad o2 sensor...

Is there settings for adjusting the voltage if its not oem. (another brand, bosch, etc). Should we stay away from cutting and splicing the (other brand o2 sensors in place....?

Does the s300 require the Honda OEM o2 sensor or does it need a special wideband sensor?

Any help would be greaty appeciated

I'd like to get this running.....

To be able to datalog AF ratios you must use a wideband such as the PLX ( www.plxdevices.com ).

Shouldn't this still read values in s300 with a stock o2 sensor?

I have one of two problems....

1) the existing o2 may or may not be working.. I gotta check this out somehow. only reads 10:1 or 17.x:1 (can't get readings)

2) I take it tuning requires the wideband.... can you still tune the *.skl without a wideband...

Sorry, Im struggling right now trying to figure this out... what exactly I need to do to get the s300 working.....( this is for a friend of mine..)

is this like the 02-04 rsx-s o2's

The stock O2 is a narrow band sensor and cannot be used to accurately read AF ratios. You are correct that tuning requires a wideband. You can make changes without a wideband, but to know if the changes you make are helping or hurting you MUST use a wideband.
