This chip cam from a standard facelift 3.0, its made by a company called Unichip http://www.unichipeurope.co.uk/dealer-network.asp The chip can be reprogrammed when you do any modifications. The wiring is soldered at the ECU plug so when I removed it I took the whole plug so it will be easy to follow the wiring when installing it in your car. £150 ono delivered
