this ECU was bought for my m6 and come to find out the dealer who said that this was the part that would fix my was actually not even close to the part that was needed ....anyways this ECU will also fit on an 05 sabercat.... i will look around to see what else it fits.... PM me for questions and i can also give you my number.... im asking $700 and this parts works as well so no worries about that
