M240i - ZF8- Aggressive Upshift
Hi,
Currently have an M240i and under hard acceleration (flooring it), up shifts in manual mode on the ZF8 have a real harsh change, almost as though the revs are not matching or the engine/gearbox is lagging behind. I used to have an M235i with a nice tune on it and under hard acceleration and manual mode i didn't experience anywhere near the aggressiveness i am with the 240 Does anyone else with a 240 experience this? thanks ! |

Does it sound alot like this guys issue - But with a ZF8 instead of manual transmission?
https://www.2addicts.com/forums/show...1510122&page=2 If so, i feel his article is explaining what i experience every now and then when im having a thrash in my ZF8 in manual mode. I'll lean hard on to the throttle and go for a quick change usually 2nd to 3rd or 3rd to 4th, and the revs will jump up and then down quickly, while letting out a little awkward burble before engaging a gear and continuing to accelerate. Sound similar? |

It's designed to give a nice kick in the ass for that driver engagement. It's not as much kick as an M car with DCT.

The kick and burp at upshifts are characteristics of a fast hard shift. M3s kick harder. My 911 was silky smooth until it was time to drive it hard, then the upshifts kicked super hard. Race cars (like 911 cup cars) kick even harder. It's how it was designed.

Take it to BMW and ask that they reset the transmission adaptions parameters
