I have to go through emissions with my 2014 S6 and I've got two systems that are in not ready state. (O2 heater and Secondary Air Pump)

I'm not throwing any codes, and I've been driving around normally for the last week. It was my understanding that these systems get checked at idle in the first 2-3 minutes, so I've been letting the car sit for a few minutes before driving in the morning.

The car has a vivid racing stage 2 tune on it with stock cats.

Anyone have any ideas on what I can do to get these systems to a ready state?

I swapped out that sensor last night and nothing changed.

Does the vivid racing stage 2 tune turn off monitoring for the secondary O2 sensors like APR? If so return tune to stock tune.

The readiness driving cycles requires various modes of driving and hot/cold starts, with some freeway.

Just thought I'd follow up on this post. The problem ended up being that the tune was interfering with the systems that wouldn't flip to ready. I had to flash back to stock, drive for 20 mins, then everything was fine.
