The 722.9 may get done some day but not in the same way as the 722.6. The .9 has a mechatronic tcu embedded in the transmission. So it really cannot get replaced. So what we do instead is make the factory tcu operate as though it is in a stock vehicle. The problem with Mercedes on this is it is part of the theft system. Also this requires a precise torque map of the engine to operate correctly. So swaps to cars that do not use a factory tq map are difficult to get right. Not something that we really sell out to the public but rather do in house. A similar project to a 6l80e swap with GM.
