    06 6.6 Duramax ECM swap

    I have a friend that that has a 06 6.6 Duramax. They told him that the ECM was bad. He we out and bought a use ECM with same part number. Truck still does not start. He ask me if I can look at it with my HPtuner. I am unable to read the ECM. I can only read the TCM. I know nothing about diesels. I use the HPtuner for my LS. Any help would be greatly appreciated. I'm running version 3.4.48.
