Is the WRX front O2 sensor "wideband"?

I have come accross mention that the front O2 sensor on the WRX is wideband. I know it is 0-5v and has 5 wires. Is it a wideband though? Or is at least accurate outside of the narrow range around 14.7?

If it is wideband, does anyone know of a good round analog (actual ratio numbers) A/F gauge that could tap into its signal?

Why bother with tapping into the front o2 sensor when you have a egt probe 11 inches down stream you can tap into with almost any anolog guage? If you are wondering were the egt probe is its located in the up pipe just after the pre cat, two inches below the turbo inlet.

Thanks for the info, I knew where all these were but am installing my Omori EGT sensor closer to the #3 (depending on your numbering scheme - but anyway the lean one furthest down the fuel rails) exhaust port to monitor its temp.

I want an AFR that is accurate over a wide band for both tuning and monitoring, it is preferable to an EGT. I have since found in my continuing search that while the front sensor is more accurate than a normal narrow band it is not wide enough to tune with still. My search for a solution I like is continuing.

install a perrin or equal fuel rail and leave the problem behind, i am running a 4 channel egt pro tune in mine i did see #3 running a bit warm untill i install the fuel rail. But if your really set on a wide band, weld a new bung into the system and install a wide band o2 sensor. But the stock front 02 sensor is not close enough to #3 to help you out.
