Shift Cut Method:
Use this list to select the method of reducing engine power during the shift cut. Possible methods
are:
Ignition Retard only
Ignition Retard + Fuel Cut
Ignition Retard + Spark Cut
Ignition Retard + Fuel and Spark Cut

Ign Retard Amount:
This is the total amount of ignition retard to allow while the shift cut is active, and the starting point
for ignition retard ramp-out after the cut turns off. Set this to zero if you do not wish to retard
timing after the shift cut.
Min value = 0 degrees, Max value = 30 degrees

Ign Retard Ramp-Out Time:
This is the amount of time it takes for the ignition retard to be ramped out to zero after the shift
cut turns off.
Min value =10 ms, Max value = 500 ms

Shift Cut Time

The Shift Cut feature allows no-lift-shifting for quick and consistent gear shifts without lifting the
throttle. No-lift-shifting can also help minimize boost drop between gears for turbocharged
vehicles. Power reduction can be achieved by a combination of ignition retard, fuel cut, and
spark cut in response to a clutch switch, a clutch pressure sensor, or a switch or strain gauge
mounted to the shift lever.
