I have read on some of the Dmax forums that some of them are running their stock ECM's autonomously in a stand alone type set up. I know that the boat guys do it as well. They usually run custom EFI Live tunes. I don't know of the advantages of this in a competition set up, but is this possible for the 6.4 for transplant use? A spartan or SCT wired right into the computer with nothing else......
