Have you got the new type S&S ECU with the different socket? There was something mentioned about it recently and you have a fairly new car. If all else fails try contacting S&S and ask them. Possibly better not to mention that you have a Morgan, just an X-Wedge engine, as they seem to get less co-operative when Morgan is mentioned. This may be something to do with the deal that Morgan seems to do with its suppliers such as Quaife and Spax.
