BMW 135i N55 DCT pure stage 2
Hi Everyone,
My shop is sponsoring a 2012 BMW 135is with N55 DCT drift car.
The car is fully built for drift events including roll cage, camber kit, hydro brake, etc....

However the owner is reporting back the since the car upshifts by itself when performing a drift.
I installed the xHP DCT tune on the car with MHD Stage 2 for N55 PWG but the car still behaves like this.
The ABG module has been coded out and disabled all the dings and dongs, also the DSC module has been coded for e-diff removed.

And of course... i had the same thought. WHY IN THE WORLD WOULD YOU USE A DCT ON DRIFT? Well.... that was his choice and we respect that, and he is good when he drifts!

Anyways, any inputs to help the car code or tune wise is greatly appreciated, even new mods for the car.
We usually don't work on drift cars, we are more into drag or circuit racing but hey... it's still a BMW and we want to provide our best to help them win.

Here's his instagram in case you are wondering about our customer:


Thanks in advance,

By all reports XHP takes care of the upshift so perhaps start there ? There are people here that know the DCT control quite well and could help.

I always wondered how the DCT would go in this environment but clutch kick and e brake implementation. How does it currently work ?

I have an N55 DCT car and xhp has fixed the autoshift at redline. Have you contacted XHP? Also, not sure if you have to be sport mode on, DSC fully disabled for that to be functional, but you may want to confirm if it is only disabled in certain settings.

Also, you dont mention what version of the XHP tune you installed. Is it the stage 3 tune?
