I've had the revised map on the car for several weeks now and it's definitely using less fuel to travel at the same speeds as before - see my pic above, with a warm engine, constant speed, i have achieved up to 99mpg. No way i could get it that high previously.
My overall average is not much difference, as i'm finding it hard to avoid using the additional performance i get with the new map, but when i'm really doing my best (driving style) for mpg then it is easier to obtain high numbers, and the max i can achieve is greater than before based on my non-scientific experimentation
