Just looked at my sticker and noticed that with computer controlled clutch. I have no Idea what that means. besides turning off MSP did you also turn on sport mode? It seems for me to get my car not to intervene at all I must do both. Edit: Did find this
Cambiocorsa
The Maserati Coupé is available both with manual 6-speed gearshift and with computerised 6-speed servo-controlled gearshift. The latter solution, called the Cambiocorsa, enables the driver to opt for manual shifting in a strong sports style (two sports settings are available) or Full Automatic.
In both cases clutch disengagement/engagement are automatically controlled by the ECU electronics. The Cambiocorsa is actuated with paddles mounted behind the steering wheel while the four available functional settings – normal, sports, fully automatic, low grip – are selected from a button panel.
