How do they control this? When the clutch depress, cut fuel? When engaged turn back on? I'd be scared to drive like that, just leaving your foot on the floor. Any inputs on how this will hold up?

 

the ECU knows everything about what the car is doing....it knows exactly what it needs to do to keep it safe while you are shifting. And since our gas pedal is electronic anyway, its no different than it already is...just adds another sensor in the mix to let the ecu know the clutch pedal is in....that way it can re-map the fuel

 

does it feather the fuel back on or just full blast? It can't be easy on the drivetrain doing that too much I wouldn't imagine
