The forum was asked if the Forte had wide band O2 sensors. Everything on kiatechinfo seemed to support that it does but could not confirm. Well, according to KIA TechTimes Volume 12, issue 2, the Forte does indeed have wide band o2 sensors. :D

Heres a quote:
In 2004 Kia introduced the Wide Band “Linear” O2 Sensor on the Spectra . We now see this sensor on the 2009 Optima and Rondo with the 2.4 engine. The new Forte will also have Wide Band sensors. These sensors are known as Wide Band because it allows the ECM to monitor the air fuel mixture over a wider range. There are new terms and new ways of testing these sensors. Listed below are some of the terms and a brief description of the function and testing of the sensors. The tests were performed on a 2007 Spectra but all the Wide Band sensors are very similar.
Incorporated in the Wide Band sensor is a standard Zirconia O2 sensor and an O2 ionpump. Between the Nernst cell and Pump cell the sensor has a diffusion chamber that is open to the exhaust stream. The O2 pump can add oxygen ions to or take away oxygen ions from the sample in the chamber. As you know, the standard Zirconia sensor produces a voltage
based on the difference in oxygen from the exhaust and the atmosphere. This sensor can change the amount of oxygen in the diffusion chamber, thus controlling the output of the sensor. The aim of the ECM is to keep the output of the Nernst cell at 2.25 volts. The ECM looks at the amount of current fed to the O2 pump to keep the Nernst output at 2.25v.
With the Wide Band O2 sensor, the ECM can monitor the actual A/F mixture through a wide range.

Awesome! Should make tuning a lot easier and cheaper! Thanks Gripphard!

Now all we need is software and an OBDII connection...makes it sound I know.
