Idle up (also called high idle) is used
to advance the throttle position on a
gas car during startup to prevent the

is warmed up.
The following Parameters
are available:
State: Inhibit or Active
Position: Adjusts the throttle
position when idle up is engaged
(0 to 100, default is 0)

Traction Control helps reduce wheel
slippage and improve acceleration
by gradually increasing the throttle.
The following adjustable throttle
parameters can be programmed:
State: Inhibit or Active
Point: The throttle position that
traction control disengages.
(5 to 100, default is 50)
Step: The distance the throttle
travels during the reduced rate.
(1 to 100, default is 1)
Delay: The time after pulling the
trigger traction control engages.
