Gear calibration
In sequential mode, gears must be calibrated. By clicking
Calibrate
it will walk you through all of the
gears and store the values for each gear in the boxes next to the gear. Numbers in boxes are values (0-
1024) where gear is detected. You should shift up & down few times to see if the range is correct and
adjust accordingly. Second box next to a gear is the window in which this gear is still valid. Alternative to
the calibration is to just shift to a desired gear and press “<” label next to the box.
AIR PRESSURE SENSOR
Enabled
if pressure transducer is installed on the bottle and connected to the GCU Pin A1. If you haven’t
specifically ordered this, this sensor is not available.
NEUTRAL SENSOR/SWITCH
This switch is used to prevent downshifts from 1
st
to N accidently. For most applications,
Type
Switch is
used. If switch is on, when it should be off (mechanically), you can
Invert
it.
CLUTCH SENSOR/SWITCH
This switch is activated when clutch is pressed, either manually or automatically. For most applications,
Type
Switch is used. If switch is on, when it should be off (mechanically), you can
Invert
it.
If switch is disabled, switch is always off so every function in the system that counts on it, will fail.
Duration
in milliseconds specifies how long we wait for the sensor to stabilize.
Typical value: 5 ms
SPEED SENSOR
Enable this if you have wheel speed sensor install (Not needed in most of applications).
H-PADDLE SHIFTER ACTUATORS
Only used if GCU is in H-paddle Shifter mode.
Window shows the position of each actuator. Before first use (or if actuators seem off), actuators need
to be configured and calibrated. Click
Setup
configure the gearbox shifting pattern (which way is
reverse, 1
st
– 6
th
gear and so on), actuator tolerance and other H-Paddle Shifter actuator related
parameters and then
Calibrate
and follow the instructions. You can calibrate the actuators using the
Test
button too. For more info on setup, see H-PADDLE-SHIFTER ACTUATOR SETUP
Test
window is only used to verify the valve connections and allows you to turn on/off individual
actuator valve.
