Understanding Low and High Speed Acceleration Rates
You can optimize a vehicle’s throttle response by conguring acceleration rates for low and high
speeds. ese rates are dened with the Full Accel Rate LS and Full Accel Rate HS parameters. You
can congure dierent acceleration rates for each speed mode.
e deceleration rates are relative to the values of the HS(High Speed) and LS(Low Speed) parameters.
See Fine Tuning Menu on page 30.
When full throttle is applied while the vehicle is traveling between the specied low and high speeds,
the acceleration rate is linearly scaled between the low and high acceleration rates.
Note: ese acceleration rates apply to both forward and reverse.
Example
Suppose you set the following parameters to the following values:
PARAMETER VALUES
LS(Low Speed) 30%
HS(High Speed) 70%
Full Accel Rate LS 1.5s
Full Accel Rate HS 3.0s
Figure 10 shows the acceleration rate when full throttle is applied.
