I have been reading Josh's thread for his 5.0 6spd and may have learned something important about having the AMG ECU, it seems it carries cruise and key information over circuit as opposed to CAN, which is good for me because the XF ECU carries this information the same way, so cruise control would work, and the car would start from the key instead of a push button.

Maybe as simple as unlocking the ECU and transferring the Immo data from the V6 ECU......

I'm hoping Josh will stumble onto this thread and maybe just confirm this information?
