Basically I need a rundown of what to download from where using which software... I tried to use the free version of tunerpro to open a 7747 bin and instead of all the info it showed on other bins there was almost nothing. Where can a get a complete 7747 .bin? does the second number on the ecm play any role in what .bin to download?(861121) How do i modify the .bins? Also if any of you bought the pro prominator with the RAD-E (switch with the cover and blue display) and having bill solder it in how much was the total?
