Car didn't do a cat warmup this morning.
Has anyone else had this? I still have it turned on but it didn't do it's whole procedure. Car was at 48F when I started it. The car did do a long and slowly lowering 1100 to 900 and then sat there. I asked trifecta to turn it off but they said it's "illegal" for emissions even though I want it off since I have a catless downpipe coming.
Could it be possible they turned it off anyways?
Here's a video, it doesn't show from the very beginning though, but you can see that the car is at 62F and it's idling.

That is because he has no Idea how to set the cold cam angles so it starts smoothly. Good MAF tuning helps too as you are in open loop so no fueling adjustment via fuel trims.

About a year ago i had too drive my car in the cold till i bought my winter beater in January. I experienced the car not doing a cat warm up many times in the cold( this was with the stock tune). When i say cold i mean anywhere from -25 too -35 degrees celsius and sometimes around -50 degrees with the windchill. It would do regular cat warm ups when it was -15 degrees celsius or warmer. Im not quite sure the reasonings for this.
