Can someone explain what happens mechanically and electronically when using launch control in the 2020 Mini?

Thank you,
Gary

 

Hi, Automotive Active Safety Embedded Software engineer here (ABS, TCS, ESC, etc). Usually two things happen:
1. The DCT transmission is asked via CAN to engage the clutches to a certain torque value, to have everything prepped. You could say this is mechanical.
2. The engine ECU is asked to run a special routine to do a spark cut on the cylinders, instead of a fuel cut, which does two things: One, the engine will be ready for an immediate launch and it will not "fall on its face" as soon as the throttle is pressed, since it is way easier to control spark ignition rather than the pressurized fuel entering the cylinder, and number two, it gives the exhaust that awesome sound just before the launch.

 

Thanks Alex,
I've got a 2020 JCW Clubman and I don't think it has the DCT transmission. It has the Aisin sourced 8 speed. Would that make a significant difference? Also won't this take a toll on the drivetrain?
