It can't.
Dinan raises the redline to 8,600 RPM on DCT cars if I am not mistaken. The is also a byte that refers to a buffer for RPM intervention. It doesn't surprise me at all that with an 8,600 RPM set in the code, that you would be able to hit 8,715. My car has hit over that on a 6MT, and the DCT will be more prone to higher shifts over the factory set limit than a 6MT.
I have read stock DCT cars that have achieved over 8,450. I would by no means consider this an 'overrev' of any sort, but BMW will certainly blame anything they can on that.
It's not true that the DME software doesn't have any influence on where the DCT will shift. |
Mike,
Thank you for the detailed explanation. Much appreciated.
