Ok, I bought one of these boxes to use with dhp. I started off with a windows 7 dell laptop and could not get framework 1.1 to install. My friend at work took the computer for me and said he had to put windows xp on it to get the framework to install which works for me the laptops just for this. I still cannot get dhp to work. When i look in my control panel franework 1.1 does not have a size but i can find it in my windows registry. Online it says that means you have it. Its the only framework i have on it currently it had up to 4 and i uninstalled them. Ive seen another guy selling one of these boxes and he said it worked flawlessly on his car. Im just so mad right now. I have a week and a half of taking all my time after work to try to get this thing working and its driving me nuts. I have been reading and reading on how to tune with dhp for months. I geuss i should have been reading on how to make the pos to work. Which i have been the last week and a half. Dont know where to go from here.
