Gear change ignition cut

This is the options screen for gear change ignition cut, also known as flatshift or no-lift shift. There are five ways you can do GCIC on a MoTeC, via:

1) gear voltage
2) a switch
3) a clutch pedal position switch
4) RPM limit
5) throttle position angle change

You also get to specify minimum RPM and minimum throttle angle before this feature kicks in, as well as the cut level, and any spark retard. The benefit? If it's programmed correctly, it will be less stressful on your drivetrain when shifting quickly through gears. On turbocharged vehicles, you also make instant boost between gear shifts. About 0.5 bar in my case. Needless to say, this makes an extremely huge difference in the way the car accelerates in an all-out effort.
