what does it mean and how should I change the values here. My cats are gutted and I have sims installed.

 

Are you getting some sort of code that is bothering you?

 

no codes here shoebox it was just suggested that I change their values and I'm trying to figure out which way I need to go.

 

I have never heard anyone talk about it. Who suggested changing the values and why? Maybe they can tell you what you need to modify.

 

Lean A/F ratios cause cats to run hot and burn themselves up. When the PCM thinks the cats may be getting too hot, it adds fuel to richen up the A/F mixture in an attempt to save the cats. If your cats are gutted, there is no reason to leave it enabled. If you are using TC OBD2 Tuner, there is a parameter for Min Coolant Temp For COT. Just set that value to a high value that you will never reach to disable COT.

 

thanx and YOU taught shoebox something. Doesn't happen all too often

 

I stick around here to learn, too. Programming has so many parameters, it's hard to keep up. I don't mess with it too much. I did see the A/F ratio setting for the cat temp. I guess it makes sense.

 

I was just playing and thanx for the help again guys
