I have a 2011 3.5L which blew up and I transplanted the engine , BCM and ECM and cluster. The only real issue I am having is my miles or km to empty is always wrong. It always reads too much and drops off very fast. When I am on empty it reaches zero, but when I am full it reads about 1.5 X more than reality will be. I am assuming this is because the truck I took the parts from may have had a larger tank and its calculating things based on that. Is there a menu where I can fix that in, or is this a dealer / fancy scan tool repair?
