The Steering Dual Rate Trim Adjustment, located at Grip Lever B, allows the dual rate value
(maximum servo travel) to be increased or decreased within a range from 100% through
20% of the total end-point value established in the steering EPA function. This function
is very useful in race conditions as it allows you to custom tailor the steering radius and
sensitivity for the current track conditions. Please note that since the Dual Rate value shown
in the “STG” screen is the percentage of the end-point value established in the steering EPA
function, the value will not always increase or decrease each time the Grip Lever B is moved.
If the Emergency Steering button function (page 17) is active, pressing Grip Button C will
restore the steering dual rate to 100% until the button is released.
To adjust the Steering Dual Rate value, move the electronic Grip Lever B either left (-) or
right (+). As soon as the trim is moved, the “STG” Steering Dual Rate screen will appear
and will continue to be displayed unless the Grip Lever B is untouched for a period of two
seconds. To reset the trim value to the factory preset setting of 70%, press the INCREASE
and DECREASE keys at the same time while the “STG” screen is displayed.
