Termi ECU compatibility question between S2R / S4R

[dark_duc]

I have been looking for an aftermarket exhaust for my 2008 S4RS and came across this Ebay listing:

http://www.ebay.com/itm/Ducati-Monster-Termignoni-Kit-Carbon-Exhaust-ECU-Muffler-Termi-S4R-S2R-800-1000-/291417610124?hash=item43d9d7d78c&vxp=mtr

Does anyone happen to know if the Termi ECU truly is compatible for the years listed?  To me, the S2R 800 vs the S4R Testrastretta are different enough that they would have different ECU's.  I cross referenced the OEM numbers and they are indeed different, but maybe that doesn't matter with these after market ones?

Anyone with experience?  I am finding next to no info Googling around.

Thanks

ecu is engine/capacity specific.  you need a photo of the other side of the ecu to get the part #.  they won't fit an s4rs as the s4rs has 45mm header pipes, not 40mm like the ones it is listed for.

Thanks Brad.  Yea, after doing some more research I realized there is no way that set is compatible.  Oh well....
