Hello all, I am new to the tuning world so far. Long story short I got impatient after a month and a half of shops and others supposed to program my truck. I found an xdf file online and tried using it with my stock bin file and have an issue. The xdf file was found from my os number.I used ls droid to install the tune. The problem I have is my truck will not start, the computer is not monitoring the transmission, and the throttle actuator is not responding either. The xdf file was for an 04 truck not my 03. I tried to install the stock bin file but it will not work. Any one have an info on what I can do to fix this? It is my daily I knew what may happen but tried it anyway. I was trying to turn fans on as I did a factory fan conversion. I have another computer coming so I will have it running soon. I can communicate with the ecm with a scan tool with out problem. Thanks
