Thanks for the comments guys,

Focus333 - I needed the 2.0 ECU and Transponder for the key. I actually use the master 1.6 key with a 2.0 transponder and it works just fine


You'll be happy to know I still have the car even after all this time.. The conversion was done at 118,000 miles and Ive just rolled onto 143,000 and she is still thundering on. Just in need of some front wishbones at the moment. Still a joy to drive.
