will the D6 barbus chip that was designed for the 320 cdi work as well on the new 350 cdi? thanks
I would assume that the chip is designed to work with a specific engine specification ( particularly in terms of the software configuation / specification). It would seem reasonable to expect that this has changed if different power / torque figures are being claimed for the 350.
Why not ask Brabus?
If the existing D6 isn't comaptible I'm sure Brabus will have one that is quite soon.
