Ya so i went around our block with my IOBD2 running just to see how it worked. I put up the screen to register what the cat temp was and was kind of shocked seeing almost 1500 degrees F. So pulled in the driveway and it was still at what the picture shows and slowly went down to 900 ish.

Then i was reading someones page and at a low millage he said he had to have his CAT replaced..... i found this article online about "How hot does a catalytic converter get?" I think hyundai may need to fix our running rich issue faster then we think or be fixing our catalytic converters all the time.
Two Important Design Parameters
The minimum temperature at which a catalytic converter begins to function, called the light-off temperature, is 600-700 degrees F.
Vehicle manufacturers usually minimize the distance between the engine and catalytic converter. This reduces the time required for the converter to reach operating temperature, which in turn reduces cold-start emissions.
Normal Temperatures and Beyond
The ideal operating temperature range of catalytic converters is 900-1,000 degrees F, although they can, and often do, operate above this range.
However, when a converter operates above 1,300 degrees F for prolonged periods, catalysts and converter components begin to melt. The result is a gradual and usually permanent degradation in performance.
High Converter Temperatures Spell Trouble
A converter temperature can rise dramatically when an engine is badly malfunctioning or for some other reason producing an excessive amount of heat and pollutants. In such cases the catalyst temperature can exceed 2,000 degrees F. When this happens the converter becomes deactivated and conversion efficiency approaches zero.

Has anyone else seen this on their car while using Torque or any other programs???
