Delayed downshifts..
It shocks me that no tuner has figured out a remedy to the delayed timing between when you push the paddle, and the transmission actually responding and shifting gears. I recently saw the thread about Eurocharged offering a tcu tune to the "first gen" 7g transmissions in order to get them to blip on downshifts but our cars already have that. My question is why are tuners not able to program it so that there is no delayed reaction?

tried this?
If you hold the paddle it show which gear is being requested and will drop down to the gear you need when u let the paddle go... everyone wants the quick taps on the paddles but benz didnt build it like that. Maybe when DCT is standard on all AMG models?

Guys, this is a software and hardware issue, a ecu or tcu tune alone will not give you immediate shifts via paddle inputs. It is a combination of tcu tuning, line pressure and the transmission type. A tc or mct trans will never be as quick as a dct. My CLK BS has a tc it and the paddle inputs were not great, my C BS has the mct and paddle input was much quicker but still left a lot to be desired. My SLS has a dct and its paddle shift inputs are almost instant, I am very happy with the dct.

I'm not a transmission expert. In fact, I think it's fair to say I know pretty much nothing about transmissions.
But I do wonder why my E39 BMW with a Steptronic has a quicker downshift and doesn't override my choices like the AMG transmission.

How did the TCU tune / valve body affect the shifting of the c63 BS? I have a FBO n/a coupe and i am sending my valve body and TCU in to weistec next week for the upgrade. No one has really done this upgrade and reported on it so I figured I can get some insight from you. Will the paddle delay be any better? How about shift times and shift "harshness" would appreciate some feedback thanks

My 2013 e92 M3 with DCT had a small delay as well, but it shifted a lot quicker then the C63's MCT. I really wish MB had put in the DCT trans into the W205 AMG.

what? lol...you shift at 4k and it shifted at 6??? what mode are you in? Are you sure the paddles on your wheel are screwed in properly? my car shifts basically the second i put the paddle in ..i mean downshifting is kinda gay cuz the computer only lets you down shift so far but upshifting isn't THAT bad...go get that checked out maybe
