Shift Cut
The ECU can decrease engine power for quick and consistent gear shift events while the driver
holds full throttle. 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. Shift cut time can be adjusted for each gear using the "ShiftCutTime"
table. After the cut time has been completed, ignition timing retard can be "ramped-out" over a
certain amount of time to decrease drive-train shock when power is reapplied.
Shift Cut Activation
Shift Cut Minimum RPM:
Shift Cut will be disabled below this RPM. Set this value high enough to prevent shift cut from
triggering when shifting into gear from idle.
Min value = 1500 RPM, Max value = 20000 RPM
Shift Cut Minimum Throttle:
Shift cut will be disabled below this throttle position. Set this value high enough to prevent shift cut
from triggering when cruising at low throttle positions.
Min value = 5%, Max value = 100%
Shift Cut Re-Arm Delay Time:
Shift cut should be disabled for a short time after each cut event, to prevent double-triggering if
the switch or sensor 'bounces' and sends an additional shift signal.
Min value = 600 ms, Max value = 2000 ms
