What is the difference between the BX1PA21GB231 and BX1US21GB231.. I know that the BX1PA is the Buell race ecm, but I am having trouble figuring out what the other one is. Thanks
My own compiled spreadsheet shows the BX1US21GB231 as a stock ECM and could be found in at least a 2004 XB12R and 2003 XB9S, but possibly others as well. Again, these are my own records but they were recorded when the ECM was taken from the actual bike.
The part# should be N0306.1AA and is superseded by a Y0152.3A8.
