Well, there seems to have problems with the ECU of my uncle car 2007 Ford Fusion 3.0 V6 AWD, such as it runs like a champ untill it gets warm. So my uncle and I intend to try reprogramming his ECU. Yet we are confused on how to connect to it and what tools to use? And is it possible to do it with a pda? Somebody recommend me the Digimaster 3 of uobd2.com, how about it?
