reprogramming the ECM is not something that you want to try in your garage.
It's way more then a do-it yourself project.
I think I can handle it on my own. I have a couple VW mechanics that are going to help me out with the changes. I'm new to this HHO thing but I've got a lot of mechanical knowlege. I've built boats, race cars and motorcycles from the ground up. I also worked for VW for two years from 2003 to 2004.
The Unisettings software that I will be using is specifically for Audis and Volkswagens. You should look on Performance Tuner websites and forums for guys who have written tuner software specific to your new model vehicle.
I've attached a screenshot of the software front screen for your viewing pleasure.
