Are all the ecms the same? My part number is Part# Y0152.1AM (2008 XB12R) and the ones on ebay have the same number but are from before 2008. Does the fact that I have DDFI III make a difference?
Yes, the ecm may have the same number but the programming on it is differnet. yours has a thunderstorm engine which uses a crank position sensor and previous models used a cam position sensor. That is just one of many differences
