Useless....
I'd be happy to be proven wrong in any case  |

We have already discussed this, the rpm is ecu limited when the brake is depressed. I've already tested this.
And it isn't your normal torque converter, it can also lock up. EDIT: And don't misunderstand this concept, every converter locks up once it meets its stall speed(rpm), our converter can lock at any speed the ECU tells it to. Which begs the question, does our converter have an internal, non programmable, stall speed that also works in conjunction with the programmable locking (gears 2-6th). OR is the locking(stalling) mechanism programmable fully, to where we can adjust when the converter starts to lock up (stall) and the smoothness of that locking.
So upon releasing the brake, can the ECU tell the converter to lock up (like dropping the clutch) for an aggressive launch, If we programmed it to do so.
It's about thinking outside the box guys and understand what if?
Also I'm looking at insight on how this specific converter is programmed and designed.

the point of having a rev limit set below the stall rpm is to avoid damage from heat
I ask these questions because in "D" (drive mode) the converter acts loosely (slushy between gears) and in "M"(manual mode) there is no slipping regardless of acceleration, deceleration, and changing gears up or down.
This leads me to believe you can adjust the stall rate and the locking mechanism and it's harshness through ECU tweaking, it's just an educated guess, but non the less needs some investigating.
