M4.4 is almost equal to standalone management actually we can almost do anything with it, even run it on wideband control, mapswitching during driving, it even does launch control and cops on 5 cyl.
The great benefit of the system is that it's with adaptive knock control, so it's "self learning" on timing within the limitations of the system ofcourse.
But any cheap ms, speeduino, kdfi stuff don't have knock sensing. So if we are able to get this working, the possibilities are endless.
Same goes for the maf size, if we could figure how to convert tables (i'm sure piet will be able to find the correct adres) then we can run BMW 540 maf or bigger.
The 5 cilinder M44 is really great, and works really nice, almost as standalone but a bit more complicated.
