Hi
How long should the test run?

I am actually doing it for the first time (myself). Have tartarini system on my V8 disko1.
It worked well for 10years
Need to calibrate it I think 😳
Never did.
I don't have lamdas connected. (Have 2) problem?
So the autocalibration runs for an hour before I just exit. It never finishes.
What should I expect?
