Dodge has lowered the temp thresholds and increased the level of intervention that the ECM takes to protect the cats. Meaning it will kill more power, earlier than it used to when the cats reach the 1701* temp threshold. In reference, I have seen my stock cat temps show 1967* and a bit higher once this was all disabled and the car was able to run freely without intervention from COT. Thats a big delta from what the cats will reach to when the car will start to reel the power/heat back. Thats scary.
Before the newer version of COT was introduced, the temp threshold was still like 1749* I believe, but the level of intervention was much less when you hit those thresholds. Meaning it was far less apparent the car was protecting the cats when you were at WOT.
When I was hitting COT, my car was completely falling on its face. BAD. Bypass would open bleeding boost, AFRs would plummet to 10.0 and less and fuel pressure at the rail would also fall to 19PSI when it was commanded to be 80PSI. Then you'd see the injector duty cycle skyrocket to 130% when it was supposed to be like 70%. All of this would happen in real time when the car would absolutely fall on its face, and I could see all of it in my HP Tuners logs.
