I know that Krazy Horse in the UK had some additional S&S ECUs that you could purchase. Not cheap but I was able to get an ECU pre-loaded with their Krazy Horse Stage 2 mapping already installed. I purchased this a couple of years back, so I am not sure if they still have any. You can contact Nobby Edwards: nobby@krazyhorse.co.uk. Nobby is always very helpful.
They ran out of these ECU's about 2 years ago...
