First off that article doesn't cover all the specifics for all the cars, just some of the major point... go figure, it's just a textbook. There's a group of engineers on SupraMania who've reverse engineered the complete TCCS... go talk to them about it, it's dizzying.
The O2 sensor isn't employed to reduce exhaust temps... it actually INCREASES them by leaning out the fuel mixture. Disconnect it and you'll be running in the 13's or richer and richer = cooler. EGR is employed to bring down cylinder temps.

Not buying it. You know jack shit about cars, probably haven't done any work on yours and have no idea what the people you paid to work on it did to it. The stock injectors can't supply enough fuel for the amount of air required for that kind of power, the ECU is programmed to cut fuel complete if a certain air flow is exceeded (keep reading I'm sure you'll get to this chapter soon enough and you can modify your story as needed then). Go back to whatever Mazda or Honda forum you usually troll on, your presence here is neither required nor desired.
God, all this jack assery has actually made me dizzy. Claims these cars don't even use an O2 sensor, then is suddenly an expert on how and when they do, what they're used for (which is also wrong) and he built a dragster out of his without making any mods?????
