There are some things in there to save the CAT but ADDING fuel KILLS cats so your claim that the NGC would be adding fuel is inconsistant.
What exact process are you reffering to?
Where did you get such an idea?
What would the NCG use to monitor Exhaust temp to induce the Fuel and timing corrections you claim??
Seems like I have a stalker now,
the last 3-4 techincal posts I've written you've fired back at me with an onslaught of Q's, Are you testing me?
If you have an areoforce scangauge, in the odbii parameters you will be able to monitor PCM CALCULATED egt's even though there is no pyrometer installed in the car. As far as what the car uses to calculate this parameter, I would guess that the O2 sensors and inlet temps would be used at a minimum but I'm cant say for sure. I would recommend contacting aeroforce and asking them as that is more up their alley.
There is a correlation of egt's and the effective afr that a specific car runs PROVIDED that initial testing has been done with egt probing and wideband testing to develop a motor. This has been done in everything from the oem mass production cars (like the SRT-4) to circle and dirt track circuits. Feel free to do your own research into this as I don't have the time or patience to try to educate you on the subject matter. It's not my idea, I don't tune this way, so I can't take claim to it for anything. I am just merely passing on an appropriate answer that seemed to fit the question.
