I have been trying to upgrade to the latest Trifecta tune using my laptop and I cannot get the laptop using either Win7 or Vista to connect to my car. I go thru all the steps while trying to tune and when trying to connect to the car I receive an error to check the cabling and make sure the key is on. The red cable is connected and I have a green light on. This is using EZ Flash 1.25. I had trouble before but it connected after @ 2nd try using Vista. Tonight no go with either Vista or Win 7. Any ideas?
