I've been exploring different Mercedes engine options for my w108 track car. The idea of a m272 came up from a 2011 GLK. Has anyone swapped these engines before or used a standalone ecu (like megasquirt) on them?

My biggest concern isnt fitment but getting the variable intake runners and swirl motors to behave if I were to run it on a standalone. I cant imagine the engine playing well with its stock ecu and partial harness in a w108.
