I am selling the YEC ECU that was used on my 2009 R6. The part number on the label: 2CO-8591A-90, and the serial number of the unit is 09385. Unit works great. Selling price: 500.00 -- includes shipping to 48 states of the USA (Alaska and Hawaii cost extra$$). Please contact me via PM on this site, or you can text or call me: 323-646-2004. Thanks, Gregg
