Awesome, glad to hear you got it working too. As for the fuel consumption, I'm not sure. I've never messed with that, but I'll try to remember to look into it for you sometime. Another thing though, just to make sure yours is all working correctly, with the truck running, connect to the Engine and ECT computer, then click on Data List at the right and make sure it's all functioning properly. Often times people will think they have Techstream working, but things like that will fail. Most people eventually get it to work by uninstalling Techstream and installing other versions. It could be related to the javascript issue TheDurk mentioned as well. I'm really not sure. Again though, congrats on your Techstream!
