Testing the launch control only on launches from 1st gear when the car shifts to 2nd gear it will shift to 3rd gear by itself way to early in the rpm range.
It doesn't matter if its in M-mode or when i launch it and throw it in D to shift by itself right after launch. It will launch and shift to 2nd gear but will shift to 3rd almost right away after 2nd.
I experienced this at the track but the issue didn't happened on wastegate pressure only when i turn the boost up enough.

here is 2 log showing examples https://datazap.me/u/mvaccarelli/dct-issue?log=1&data=3-17
do you have any idea why the car shifts to 3rd by itself regardless? if i start the car from 2nd I can rev it all the way through the range. It only happens when launching from 1st gear.
i can be in Manuel mode or throw it in drive mode after launch wont let me rev all the way through 2nd gear.

It’s the auto shift at redline. When the wheels are spinning and the revs shoot up fast the car auto shifts. Happens on my 135 as well. It’s Super annoying. That’s why I am praying all the smart people in this forum figure out a way to disable it or to get the M hw or sw working with the 2.56 diff. The M cars don’t auto shift.

its so werid because it doesn’t even feel like the tires spin that much at all it literally shifts to second and even continues for another 500-1000 rpms to around 5500 and then shift to 3rd it’s so stupid lol
