![Question](https://www.rx8club.com/images/icons/icon5.gif)
I saw a air/fuel ratio gauge at Discount Auto Parts;
I did not get it because you need to splice into the O2 sensor wire from the cat.
I felt that adding/subtracting resistance or changing the Ohms sent by the O2 sensor would mess up the ECU.
Any thoughts on that; or do other "wide band" gauges get around splicing the O2 sensor?
Am I misunderstanding my O2 sensor or ECU; or am I just under-estimating the "Wide Band" gauge maker?
Thanks.

Your OEM wide band is not 'normal'. It's a current based usnit specifically for the RX-8 and its ECU. You can add another one, but it would be completely independent of what's there.
