- Ignition on, wait 20 secs, then off again.
- Ignition on, wait 20 secs, start engine.
- Without touching anything let the car idle for 1 minute.

I even timed the one minute yesterday because it was late and I didn't want to let the car idle for too long unnecessarily (neighbors bedroom facing my driveway).

Anyway the log shows AVCS is not active at all:

So I suppose 1 min wasn't enough for the calibration to complete?

If AVCS stayed at 0 during the drive, I suppose that would throw everything off including MAF?

P.s.
The load change is the only thing changed (OL fuelling back to normal):
