Installation and Setup - Quick Shift, Datalogging, Speed Limiter, Shif

The Interceptor has 8 Expansion pins which can be used for many features, including reading switches and voltages (inputs) and controlling devices (outputs).

Depending on the model of bike, up to 3 of these pins may be in use by the standard cable for wheel speeds and gear position, leaving the extra pins to be used by many of the Interceptor features.

To connect sensors, switches or devices to your Interceptor, simply insert an Expansion wire into the appropriate pin, and enable that function to suit. See the end of this page for a wire connection chart to accompany these instructions.

Quick Shift

The Quick Shift function cuts the engine for a programmed period of time when triggered. This allows for 'clutchless' time saving upshifts, simply hold the throttle wide open and shift up to the next gear without using the clutch lever.
The quickshift trigger can be a pressure switch or sensor on the gearshift lever rod, or a manual pushbutton. All types of switch, voltage pressure sensor or use of existing handlebar switchgear buttons are supported.

Installation of the quickshift trigger involves connecting a single signal wire from the quickshift trigger switch or sensor into one of the Interceptor Expansion pins. Any Expansion pin can be used, though for these instructions we will choose Expansion 5 (EX5 pin B7).

Quick Shift Installation
For a two-wire switch or sensor that is not connected to anything else, insert one wire into Expansion 5 (EX5 pin B7), and the other wire into Sensor Ground (SGND pin B12).
For a single wire switch or sensor (where the other side connects to Ground ro provides a voltage when triggered), insert the single wire into Expansion 5 (EX5 pin B7).
The polarity, voltage range or trigger method doesn't matter at the installation stage here, the Interceptor can be setup to sense and trigger from any signal type.

Quick Shift Initial Setup
To setup the quickshift operation, start the Interceptor PC Software and open the map previously saved from your bike, or connect to the Interceptor live via the USB cable. Open the Folder Tree to show all adjustment folders by pressing Ctrl-F (hold down Control and press F) or select View > Folder Tree in the menu.
You'll see the main folders on the left, Fuel, Control, Setup and Notes.
Click on the [+] next to Control, then the [+] next to Quick Shift to expand the Quick Shift section.
Open Cut Start Setup, we will now choose the switch/sensor input pin and voltage to trigger the cut.
Recommended settings for any switch type of trigger are:

Control >> Quick Shift >> Cut Start Setup
Name	Value	Description
Cut Method	Cut Fuel	Quick Shift Cut Method
Cut Sensor Input Pin	Expansion 5	Expansion Pin
Cut Sensor Input Pullup Resistor	On	Off, On
Cut Trigger Voltage	2.500	AD 5 Volts
Cut Trigger Hysteresis	1.000	AD 5 Volts
Cut Trigger Direction	Falling Edge	Falling Edge, Rising Edge

If instead you are using a different Expansion Pin for the quickshift trigger instead of Expansion 5, select it for Cut Sensor Input Pin.
The Cut End Setup folder can be left unchanged. It's for the less common strain gauge, linear voltage or dual-switch quickshift triggers.

Next we setup the Cut Time. This is how long in milliseconds (ms) the engine cut will last to allow the upshift with engine power removed. Usual values are in the 70ms to 100ms range, often starting aroung 100ms at low rpm, and reducing to 80ms at higher rpm. Different engine and gearbox types will shift cleanly with different cut times, the goal is to set the lowest cut time that allows a perfect shift at all engine rpm and riding conditions.
The PC Software has a handy tool to create curves on any table like this, the Curve Wizard. With the Cut Time folder open and the grid and 2D graph for this table visible on the screen, choose Setup > Curve Wizard in the menu. The Curve Wizard tool opens and we can quickly create a cut time curve.
In the Point 1 box, enter 100 for milliseconds. Tick the Point 3 box, enter the redline for your engine in RPM (eg. 15000) and enter 80 for milliseconds. In the Point 4 box, enter 80 for milliseconds. Press Apply and this new Cut Time curve will be written to the map.
Now we have a detailed Cut Time for all the engine rpm conditions. To offset or adjust this curve, use the Curve Wizard again, or click the 'ms' cell on the left of the grid to highlight all the cut time values, and use the < or > hotkeys to move all the cut time values up and down.

Turn on Quick Shift
Lastly, to enable the Quick Shift function operation, click on the Quick Shift folder name directly. A dial and pushbutton are ready to operate on the screen. Set Quick Shift to "On" and Active Above RPM to "4000". Active Above RPM prevents the quickshift cut from operating at idle or lower rpm when changing gears stationary for example, and can be adjusted to the rider's preference.
You can turn on or off the Quick Shift function at any time, and move the Cut Time to suit your engine and rider preference.

Datalogging

The Interceptor will datalog directly to a USB Memory Stick at any time you choose. A new log file is started any time the Start conditions are met, and the log file is saved and closed any time the Stop conditions are met.
A manual switch or pushbutton start/stop is also supported if you prefer.
Any USB Memory Stick can be used, some support faster writing speeds than others.
Log files saved to your USB stick can be viewed and opened in the PC Software with the Datalog tab and Open Log button.
To setup or change the Datalogging start and stop conditions, open the Folder Tree to show all adjustment folders by pressing Ctrl-F (hold down Control and press F) or select View > Folder Tree in the menu.
Click on the [+] next to Setup, then the [+] next to Datalogging to expand the Datalogging section.

Setup >> Datalogging
Name	Value	Description
Datalogging	Enable	Disabled, Enabled
Start and Stop By	Automatic	Datalog Start Method
Log Frequency	50Hz (20ms)	Frequency Hz
Log Time Limit	0	Seconds
Log Restart Delay	0	Seconds
USB Log File Prefix	BIKE	Text 4 chars long

Rename "BIKE" to whatever 4 letter prefix you like for your files. The files will be named BIKE0001.CSV, BIKE0002.CSV, BIKE0003.CSV and so on.
Then click on Automatic Setup, we'll set the speed and rpm to automatically start and stop logging.

Setup >> Datalogging >> Automatic Setup
Name	Value	Description
Start Above Speed	30	Speed
Start Above RPM	0	RPM
Stop Below Speed	30	Speed
Stop Below RPM	3000	RPM

These values are set so that logging will Start as soon as the speed is over 30 (kmh or mph depending on speed setup) and rpm above 0. Logging will Stop as soon as both the speed AND rpm are below 30 and 3000.
Note that for the stop logging conditions, both the speed AND rpm must be below 30 and 3000, this is intended so that the engine is returned near idle and the speed is below 30 before it writes and closes out the log file.
It's important that the log file be stopped, written and closed out before the ignition is turned off, so be sure that the bike is pulled to a stop at idle for a few seconds before turning the ignition or kill switch off.

Speed Limiter

The Speed Limiter is commonly used as a Pit Lane Speed Limiter, enabled by a switch on the handlebar.
Any time the Speed is above "Speed Limit When Active", the engine will be cut, preventing the bike from exceeding the set speed limit.

Speed Limiter Installation and Setup
Run a single wire from your speed limiter switch to any free Expansion Pin on the Interceptor. The example below shows Expansion 6. The other side of the speed limiter switch should go to Ground (the frame ground, battery negative, etc) when the speed limit switch is on.

Control >> Speed Limiter
Name	Value	Description
Speed Limiter	On	Off, On
Speed Limit When Active	60	Integer
Speed Limit Input Pin	Expansion 6	Voltage Input Source
Input Pin Active Level	Low	Low, High

These example settings will limit the speed to 60 (kmh or mph depending on speed setup) any time the speed limiter switch is low (grounded).
A good speed signal is important to the speed limiter operation, ensure you have a speed signal on your bike, and that the values in Setup >> Speeds >> Speed and Delta Speed are ok.

Shift Light

Up to 4 stages (lights) of Shift Light are supported, the lights being directly lit and controlled from the Interceptor.
1 or 2 stage is most common to use. Expansion Pins 1, 2, 3 and 4 support driving shift lights by
'low side driving' to ground any connected light, with up to 1 amp permitted. The shift light(s) should be connected with their positive side to +12V ignition, active when the ignition is on, and the negative side directly to the chosen Expansion Pin on the Interceptor.

The following example settings show a Shift Light (1 stage) on Expansion 4, set to come on at 200 rpm before the Shift RPM, and Flash exactly at the Shift RPM. The Shift RPM is set higher in each gear to allow for the rider reaction time in lower gears to upshift and keep off the rev limiter.

Control >> Shift Light
Name	Value	Description
Shift Light	On	Disabled, Enabled
Shift RPM Gear 1	14000	Integer
Shift RPM Gear 2	14000	Integer
Shift RPM Gear 3	14100	Integer
Shift RPM Gear 4	14100	Integer
Shift RPM Gear 5	14200	Integer
Shift RPM Gear 6	14200	Integer
Stage 1 RPM Separation	200	Integer
Stage 2 RPM Separation	0	Integer
Stage 3 RPM Separation	0	Integer

Stage 1 Controlled Pin	Expansion 4	Switched Output
Stage 2 Controlled Pin	None / Internal value	Switched Output
Stage 3 Controlled Pin	None / Internal value	Switched Output
Stage 4 Controlled Pin	None / Internal value	Switched Output

Expansion Pin Wiring

The Interceptor has two connector bays, the "A" and "B" connector. All Interceptors are supplied with the A connector as part of the fitment cable to the bike model. The B connector and pins are available from Interceptor Electronics for additional setups where the Expansion 5, 6, 7, and 8 pins may be used for additional sensor or switch inputs.

To insert a new wire or pin into the connector, remove it from the Interceptor, and gently push the two exposed white tabs on the sides of the connector housing upwards. This will raise the white anti-backout plate about 1mm. The anti-backout plate is not removable and only needs to be raised for new wire and pin insertion.
Insert the new wire with pin into the rear of the housing until you hear a small 'click' showing that the pin is fully seated.
Lastly, push down the white anti-backout plate so it is again flush with the top of the black connector.

Rear (cable wiring) view of the Interceptor connectors, Expansion Pins are shows in yellow.

Interceptor Pin	Input Capability	Output Capability	Common Usage
Expansion 1 (EX1), pin A11	Voltage, Switch, Sensor, Speed	Low Side Driver	Rear Wheel Speed Sensor (RWS)

Expansion 6 (EX6), pin B8	Voltage, Switch, Sensor		Speed Limiter switch
Expansion 7 (EX7), pin B9	Voltage, Switch, Sensor		Map A/B switch
Expansion 8 (EX8), pin B10	Voltage, Switch, Sensor		AFR Module (Wide Band Lambda)
Signal Ground (SGND), pin B12			Extra Sensor/Signal Ground, can be used for ground reference on suspension travel and other sensors if required.
+5V Auxiliary/Sensor Power, Pin B17			Supplies +5.0V DC at 200mA maximum if required for suspension travel or other sensors if required.

All 8 Expansion Pins have programmable pullup resistors, which can be turned on within the function that uses them, or separately via Setup >> Expansion Port >> Expansion Pin Pullup Resistors.
