2.7 SPEED BOOST OPERATION
ClearCommand is capable of providing a transitory speed signal
(speed boost) to the governor during clutch engagement to decrease
the possibility of stalling the engine during a reversal. It is recom-
mended to only use Speed Boost if required to keep the engine from
stalling on a through shift, such as a reversal.
After the Speed Boost Start timeout has expired, throttle will raise to
the Speed Boost Percentage. The throttle signal will remain there until
the Speed Boost Timeout has expired. If Speed Boost is active, Speed
Boost will be applied on every shift from Neutral.
When adjusting Speed Boost, begin by leaving the Speed Boost Start
Timeout at the default value of 0 seconds, and work with the other two
Speed Boost parameters to acquire the required Speed Boost to keep
the engine from stalling. Refer to Section 8.2 for further explanation
on adjusting.
