COT - Cat over Temperature

[MadMarx]

I would like to know about this option.

After about 10 seconds of full throttle suddenly I do see a lot of spark retard and an enrichment which jumps up from 13 AF to 10.5 AF.

I suppose I do see the COT protection?

How do the ECU estimates the cat temperature?
It is advisable to disable this option?

I also saw an option called piston protection. How does this work? I can't see any adjustments there, only the rpm on which the protection does start.
Maybe I can put the value more high to disable the piston protection?
What could happen then?
Older engines never had piston protection.

if you have a lnf everyone here disables it because it steals power. it doesn't even do much damage to the cat with it disabled and running a good tune.

if you do have an lnf, the ecu uses advance, fuel ratio, intake density to calculate egt. it gets close but its still not as good as an external sensor.

I generally change the Max enrichment table for COT.

Obviously if the car is cat-less there is no harm in disabling it along with the car warmup option.
