2003 250XS ECU Compatibility

[JWolff]

I want to buy a second ECU for my 250XS to see if I am getting the same issues with a different ECU. Can anybody tell me what other models/years of motors I can look at? Right now I am assuming 2003-2005 250XS's only. These have the lower rev limit and higher octane requirements.

2005 was the first year for the 6300 limiter. I'd say you need an ecu from a 2003-2004.
