Is this probe mobile and he'll drive around with it hooked up or will the car just sit while he revs the engine? I'm just trying to look into what he'll be doing so I have a better understanding before I bring him the car.
He is most likely going to adjust your CO at idle and that's it. "Almost" useless if you think you have any real afr issues. That's the way the Porsche manual says to do it and they way shops have done it for decades. That was before the days of the adjustable Warm up regulator, which your stock wrench may not know about.
