Wideband

[jr86211]

I wanted to know if I disable the O2 sensors can I remove one of the sensors and put a wideband sensor so I can monitor my a/f ratio. I am not sure hows this works but I would like to be able to monitor my air/fuel ratio to make tuning a little easier. Also, what is the ideal ratio for power? I know 14.7:1 is best for emissions but I heard 12.5-13.1:1 makes more power

Thanks

You can remove a rear O2 sensor, but leave it plugged in to the harness.

Look for 12.3-12.5:1 for best power on the Hemi.

How do you measure the air to fuel ratio? Does the tuner provide this information? Is it done via datalogging?
