    C7 z06 a nice cut?

    Hello!
    As you may know, the C7's cut-off at maximum RPM is very unpleasant...
    and even more so with an automatic gearbox.
    When it reaches maximum RPM, it simply dies, and you have to wait several seconds until it drops in RPM for it to resume and then let you change gears and have power again...
    It is very difficult to change gears with the steering wheel paddles... it has a lot of LAG, and if you also hit the limiter, the car dies for a few seconds. It is super uncomfortable...
    Is there a well-tested and safe configuration possible, so that it works "normally"?
    In other words, when it reaches maximum RPM, it cuts off by banging bang bang bang bang, and the moment you press the shift lever up, it changes gears (taking into account the lag of the paddles, which cannot be fixed), and it does not stay there for half an hour...

    Yes it can be done. Is it safe? The AFM lifters don't like it very much so its up to the owner. The shifting in the A8's and paddles are terrible. It can be improved but not by a lot.

    It can be adjusted in the tune as Jason mentioned.

    Thanks for the answers..
    My previous C7 was a Z51.
    I had a tune done, and I modified the RPM cutoff a bit.
    Can you check if I did it right? or is there something to improve?
    Can I apply this modification to my Z06 with the intention of improving the response when the limiter is reached..
    At the same time I could do the same but increasing 100 RPM.. or does this not have any positive effect? ​​
    I attach the original and modified from my ex Z51.
    In the cutoff tab you can see the modifications.
    Hysteresis at 0.. I don't know if it's the best..
    and Switchover Delay at 0 I suppose this makes it possible to make an upshift even when reaching maximum RPM..

    Please review and advise me to apply the changes to the Z06, I have little experience..

    Can any expert review the file??
    I see that it is very difficult for people to share their wisdom in this forum..
