Best launch technique on DCT not using LC?

However, shifts from 2-3 and subsequent shifts do feel like DSC is off. It seems to manage the actual launch and the 1->2 shift only.

I feel exactly the same.
LC uses MDM to control wheel spin.

Assuming you guys are correct, I wonder if it is the same on non-ZTP cars.

I know that if I launch by mashing the pedal to the floor (i.e. passed the detent), my car will lay down a patch of rubber whether I use LC or not. In fact the two types of launches feel pretty similar to me. So I wonder if this is only because I don't have ZTP? Of course MDM is just software so its not like the car could not be behaving in the same way for both non-ZTP and ZTP cars if they wanted it to.

^ part of the reason to get ZTP - it is required to get MDM (in the US). I expect only MDM cars offer this "sporty" version of the full DSC/"nanny" mode. I am not surprised by your comment about excessive wheel spin. MDM is definitely worth the money both to control wheelspin when in drag like situations as well as to offer a bit more sport dynamic control in the corners, i.e. limited under/over steer.

how would suspension matters?

Suspension mode affects shock damping which affects fore-aft weight transfer which finally affects traction.
