OK trying to get a grasp on what all is included when you buy a vtech and credit. I'm thinking about picking up an ecu and maptuner from the classifieds and I'm a bit confused. The ecu is already unlocked in the map tuner but its an older maptuner and I'm hearing it needs a firmware update? Ifthe ecu is unlocked I should be able to load any tune vtech has without additional cost? What about the map editor? Is there something extra I need to buy to have editing capability? I'm a noob to vtech but use hptuners and FAST XFI software for all my lsx tuning in the car world and its a little confusing since we don't have real usable "libraries" for tunes to just load and go. Also hows the data logging for the maptuner work? Is there any? I know there's probably answers to most of this but couldn't find straight answers....
