If you understand that the new "pay" (ECM Mono) version of ECMSPY works with -ALL- Buells, as stated on the official ECMSPY website at the link Ich provided, then Ich is correct. ECMSPY (Mono) does work with 2008+ Buells, and can indeed be used to switch off the Noise Abatement within that software.
The link that Lunatic provided as a counter-argument to Ich's post regarding ECMSPY's ability to work with 2008+ X-bikes specifically mentions the OP providing copies of ECMSPY software to others, a dead giveaway reference to the older free/legacy version of ECMSPY which does -NOT- work with 2008+ X-bikes.
In summary-
-- ECMSPY Mono and Tunerpro can both be used for tuning -ANY- production Buell motorcycle. ECMSPY Mono is pay-to-play, Tunerpro can be used at no cost.
-- The legacy ECMCPY (I believe version 1.27 was the last distributed release) can be used for tuning 2007 and earlier Buells. It was not developed to support 2008 and newer Buells.
