The main rule to solve a problem , ofter valid in other field , is to follow a line from INPUT to CONTROLLER and finally the OUTPUT .

In our case the INPUT is the sensor , the CONTROLLER is the strategy and the OUTPUT can be checked on data acquistion .

Sensor Setup ( the INPUT )

To setup correctly the Gear Shift some simple checks should be made .

First of all theLoad Cell Sensorshould be checked :

Configure the Load Cell sensor ( menucalibration /load cell force)
1. Set the Offset to the same value You read onLoad Cell Analogchannel
2. Set the Gain to the value You can read on Your sensor datasheet ( usually 500 N/Volt ) , set the sign ( + or – ) to obtain a positive value onLoad Cell Forcechannel applying a force to increase gear ( 1->2->3 and so on … )

Strategy Setup ( the CONTROLLER )

ForGear Shift Up:

Enable the gearshift from Working Modes ( menuRider Setting / Workmode Setting)
Setup the basic features only ( menuGear Shift / Gear Shift Up Enable)
1. All Options = OFF
2. Debounce Time = 200 mSec
3. ReArm Force = 150 N
4. Trigger Force = 250 N
5. Min GAS = 20 %
6. Min SPEED = 0 km/h
Setup the CUTS ( menuGear Shift / Gear Shift Up Cuts)
1. TDC Loop Size = 10
2. For All gear ( included default ) Set Cut Timeout = 70
Switch OFF both IGNITION and INJECTION ( menuGear Shift / Gear Shift Up Cuts)
1. Set INJECTION Pattern #1 = 00000000
2. Set IGNITION Pattern #1 = 00000000

ForGear Shift Down:

Enable the gearshift from Working Modes ( menuRider Setting / Workmode Setting)
Setup the basic features only ( menuGear Shift / Gear Shift Down Enable)
1. All Options = OFF
2. Debounce Time = 200 mSec
3. ReArm Force = -150 N
4. Trigger Force = -250 N
5. Max GAS = 10%
6. Min SPEED = 0 km/h
Setup the BLIP ( menuGear Shift / Gear Shift Down Blip)
1. For All gear ( included default ) Set Cut Timeout = 200
2. Setup the whole table for Target TPS = 20 %

Data acquistion check ( the OUTPUT )

After setting up everithing here above , You can check what happens on data acquistion . You could setup Your data analyzer with following channels :

RPM , TPS , SPEED
LOADCELL , GEAR_POS
CUT_LEVEL , CUT_FUNCTION , STR_FUNCTION
GEARSHIFT_UP_SM , GEARSHIFT_DN_SM

It would be perfect if You can show STR_FUNCTION using a BIT MASK instruments ( You could check Your data analyzer functionality ) . Check theSupersport Channels Explainedpost for more details .

Now You can check if all “chain” work like should .

So when rider press pedal ( LOADCELL ) value pass the TRIGGER THRESHOLD , then the STR_FUNCTION must signal the GEAR SHIFT strategy active , and CUT_LEVEL must be 100 % ( for GearShift Up ) , and TPS move up ( for GearShift Down ) .

If something don’t happens like expected , made some step back and check Your configuration .
