It might be true for manual mode. What I'm thinking is just a simple comparator or buffer placing between shifter and EGS. When EGS see the slow falling edge of the EGS_UP or EGS_DN signal, it shifts up and down accordingly.
EGS_UP/DN falling edge might be slow, so a high-speed buffer would help. Whenever it senses a falling edge of EGS_UP/DN, it'll trigger the output right away, and this might cut some propagation time.

Seriously, I have heard that installing a new lightened fliwheel shifting times would be receduced : is it true, in your opinion ?

Yeah! He said that the difference between new and old steptronic box is just a software improvement. An external chip should cope with this task.

No, no, no... The difference is not software only! Most definitely physical changes including a lock-up clutch as well as the torque converter...

You are right, Colejl, and I was wrong.
