I have COT temperature turned off while I'm VE tuning. I did a long pull on a hill last night to populate cells and by the end my Cat temperature was 1660*, then immediately came back down when the load went away back down to 1400-1450. When I stopped I thought my brakes were overheated because it had that hot brake smell outside the car. I think maybe it was the cat making that smell? Did that hurt it?
How does temp threshold 1-3 work. I guess threshold 3 is first since it is the lowest number?
