Today I asked the service guy at the local Dodge dealership if there had been programming updates for my truck's ECM. They appeared puzzled by the question. The truck is a 2006 3500 diesel 48re. When I came back to pick up the truck a different service guy said there were no programming updates. From reading this website as well as others I got the impression that ECM programming updates happened regularly. How can I confirm whether or not there are flash updates from Dodge for my truck? Are there ECM programming geared for trucks towing 15000# plus?
