hey there I own a 1990 ford sierra sapphire cosworth 4x4 and am in the process of a power upgrade but have hit the ecu hurdle and am in two minds as which one to use: I know the top guys in england are using autronic and was going to follow suit but have also heard good things about the link g3 computer being used in the cosworth in new zealand. if anyone out there has a "cossie" and is using a link computer could you let me know how it is going and if there are any problems/tricks for using this system. cheers hadyn
