I would like to see if there are different part numbers for the different stock ECMs.
ie. mine is:
2006 ULysses Y0152.3A8

Dave,
That is the part number for ALL ECMs after 2003, XB9 or XB12. The hardware is the same, and the part number you've listed is the HW. The ECM gets flashed somewhere on the line after it is installed in the bike, and that's when it becomes an XB12 or XB9, Domestic, Japan, or European variant.

That is why the XB9 ECMs, and for that matter, even the race ECMs, all have the center pin for the muffler servo, even though they don't use it.

Thanks AL! Do you think they flash all of the Domestic ECMs with the same program?

Al, don't the 12 ecm's have the extra output between the plugs for the exhaust valve that the 9's don't have?

Same ECMs, different maps AND algorithms, though even the algorithms are almost certainly virtually identical outside of the servo control. It would make zero sense to make them with different HW when they are 99.9% alike in function and performance requirements.

03 ECMs, stock and race, don't have the center pin, as there were no XB12s and therefore no exhaust servos to control. In 04, the HW is all the same.
