It has been about a month and 800 miles now and the latest software update seems to still be working great. No signs of the adaptive controls having any effect on it. It not only has eliminated the hesitation problem but also has improved overall throttle response. My gas mileage seems to have reduced a bit but I think that is more from the way I am driving it now. It's a real joy to drive now. I think this might finally be the permanent fix this time.
Has anybody else had the update done?
