I know this is an older post, but wanted to clear something up. Swapping ECM's on the 07.5-later Dmaxes won't work either. Problem is they store the exhaust filter cleanings (regens), and your stock ecm won't show any for whatever length of time you have it swapped out. Dead giveaway that the ecm was removed as the filters can't go very many miles without being cleaned through the computer.
