Obviously this question is similar to How to improve fuel economy in high-mileage car? except I am asking specifically about automatic transmission car.
The car still delivers lots of power/acceleration but the fuel consumption is very high. Maybe this is a naive question but could I somehow set up the automatic transmission software to trade power for fuel efficiency?
EDIT:
My car is 2004 Ford Mondeo XL 2.0 Petrol and fuel consumption is cca 15 liter per 100 km (15.7 MPG) in a city.
