Went for emissions and cats & EVAP monitors are not ready

I passed once already with this car two rears ago. The only thing that has changed is a tune by Moncef at AdminTuning.

I have driven thousands of miles since having the battery cable off last. Including a road trip. I tried to do the "drive cycle" this morning but no dice.

​​​​​Little background info: I never let my car fully warm up to temp before driving. Is this preventing the cat monitor from completing? I did it this morning but nothing changed

I never cruise in this car. It's driven in the city or spiritedly on the highway. If I do cruise I use CC. Do I really need to try to drive between 53-56 for six minutes straight? That's nearly impossible where I live unless I take an hour and a half road trip outside the city.

Any suggestions? Does anyone know the right drive cycles for these two tests? Thanks in advance. All advice will be appreciated.

Most likely the tune shut off the cat and evap monitors, did the tuner know you needed e-test?
As far as the monitors, I believe the evap needs a cold start followed by a city run, then a highway run, then a city run. Cat needs a highway run with decel on engine, and mild accel then cruise for a couple minutes. Don’t quote me on that because it’s been a while since I’ve done them, but a drive to my house and back (20min each way, mixed) after a cold start usually got both monitors to pass

The tune is the issue. You need to contact Moncef or pay a guy under the table to pass.

Does the tune shut off the monitors?

I received an email back from Moncef. He did shut them off. He sent me a file to upload to the car. Said this should let me ready the monitors.
