Does anyone here know the complications around not having the auto ECU?...do we need to fudge some inputs/outputs?...im in the dark when it comes to autos but its a mercedes and at a guess the ECU probably reduces power between gears to help smoothness??....

At the end of the day if the engine behaves normally without the auto ECU this swap will be incredibly easy.
