-B Tuning the Throttle Max
1. Jack the vehicle wheels up off the ground so that they spin freely.
STEP
2. Plug the programmer into the controller and turn on the key-
STEP
switch and interlock switch (if used).
3. Select the Monitor Menu. The Throttle % field should be visible
STEP
at the top of the display. You will need to reference the value
displayed here. For convenience, set a bookmark here so you can
return easily to read the Throttle % value.
4. Rotate the throttle forward to its maximum speed position and
STEP
observe the Throttle % value. This value should be 100%. If it is
less than 100%, the Throttle Max parameter value must be
decreased to attain full controller output at the maximum throttle
position. Use the programmer to decrease the Throttle Max
parameter value, and repeat this step until the value is 100%.
Setting a second bookmark at the Throttle Max parameter will
allow you to toggle back and forth easily between the parameter
and the Throttle % field.
5. Now that the full throttle position results in a 100% value for
STEP
Throttle %, slowly reduce throttle until the Throttle % value
drops below 100% and note the throttle position. This represents
the extra range of motion allowed by the throttle mechanism. If
this range is large, you may wish to decrease it by increasing the
Throttle Max parameter value. This will provide a larger active
throttle range and more vehicle control. Using the programmer,
increase the Throttle Max parameter value and repeat the test
until an appropriate amount of extra range is attained.
6. If a wigwag throttle is being used, repeat the procedure for the
STEP
reverse direction. The Throttle Max value should be selected such
that the throttle operates correctly in both forward and reverse.
