[Dualist]

You need all three items otherwise it ain't gonna work mate, they have to match each other and come from the same car.
Stevestrange is a seller on ebay who breaks porsche, ferrari's and all nice cars and knows what he's doing. All my numbers matched on the ecu and dme and were also the same model and year type, it all has to be perfect.
Find a ecu + dme that match your numbers that also include a keyfob as you will need the pill inside. Always best to do initial start up too by turning ignition to position one for about 1 minute then off (for the throttle valve to recalibrate) then on for 15 seconds then off, then it should start ok.
Click the refund button and send your unit back mate.
I got mine all sorted for 175 notes.
