Ive got 442 on mine mate ask me anything you want or add me on gram and have a look etc ive done a rough base map myself but the ME boys will be taking care of it for me next month. The support they offer is what won me over, over all the other ecu brands i contacted. It totally depends what you want from an ECU, OMEX 600/710 are both super capable for the zetec and there are some awesome mappers out there, i wanted to go with something different and ME fit what i was after plus they are only down the road from me!
