Easy-Shift Kill Box Installation Instructions



Part # ES-1001 page 1

Easy-Shift Air-Shifter Kill Box

• Kill time is digitally controlled with DIP switches for accuracy. Settings range is from 30 msec (0.030 seconds) up to 100 msec.

• The Easy-Shift kill box actuates the air shifter solenoid so that shifts are not missed due to short presses of the button.

• Solenoid actuation time can be extended for hard-to-shift bikes.

• Auto shift function can be added by simply connecting the output of a shift light controller.

• Dual polarity actuation inputs can work with horn button circuits that switch ground or 12V.

• 0.400 Second delay between shifts prevents unintentional double-shifting.

• “Softer” ignition kill circuit can prevent backfire in most bikes.

• Harness and wiring instructions included for ease of installation.

Easy-Shift Air-Shifter Kill Box Features

1. Kill time is digitally controlled using DIP switches inside the box.

2. The air shifter solenoid is controlled by the Easy-Shift kill box so that shifts are not missed due to short presses of the button. Solenoid actuation time can also be extended for hard-to-shift bikes.

3. Auto shifting can be done by simply connecting the output of a shift light controller to pin 7.

4. Can be activated with horn button circuits that switch ground or 12V.

5. 0.400 Second delay between shifts prevents unintentional double-shifting.

Connect to one wire of the air solenoid

1. Switched 12V Connect to switched 12V

2. Ground Battery Ground

3. Coil 1(-) Connect each of the 4 coil (-) wires to a

4. Coil 2 (-) separate ignition coil (-) terminal. If

5. Coil 3 (-) there are less than 4 coils on the bike,

6. Coil 4 (-) leave the unused wires unconnected.

7. 12V to Shift For auto shift, connect pin 7 to the light output of a shift minder

8. Shift Solenoid (-) Connect to one wire of the air solenoid

9. Ground to Shift Activation button

(The button must switch ground to this input)

Female 9 Pin Harness Side Connector

Wiring Instructions

Use the diagram above. The pin numbers run in order through the 3 rows of the connector. Row 1 is pins 1-3, row 2 is pins 4-6, row 3 is pins 7-9.

The red wire is pin 1. It should connect to key-on power. The horn fused (10Amp) circuit is a good source.

Pin 2 should be connected to battery ground.

Make sure the coil connections are to the negative side. (Usually, the positive wires are all the same color.)

Pin 9 is the typical shift button input. The horn button may be used for this on most bikes. Check with a meter or wiring diagram of the bike to be sure that the activation button switches ground to the circuit. If it switches battery voltage, it may be connected to pin 7 instead.

Pin 7 may be used for an “Auto Shift” input. Connect the positive shift light activation output from a shift light controller to trigger the shifter. (Shift light controllers that switch the ground side may be connected to pin 9.) NOTE that this has been tested with a Dyna Shift Minder to pin 7. No other products have been tested.

Pin 8 controls the air solenoid negative side. Connect the other wire of the air solenoid to the black wire at pin 1.

DIP Switch Settings to set your Launch Master

Remove the 4 screws and the cover from the kill box.

The base kill time with all DIP switches off is 30 msec (0.030 seconds).

Switch 1 adds 10 msec to the base time.

Switch 2 adds 20 msec to the base time.

Switch 3 adds 40 msec to the base time.

(Example: for 60 msec (0.060 sec) switch 1&2 on, switch 3 off.)

It is recommended to start with switches 1-3 on (100 msec kill time), then work your way down. Most sport bikes work best at 50 msec (switch 2 on, switches 1 & 3 off).

Switch 4 effects the air solenoid actuation time. With switch 4 off, the actuation time is 50 msec longer than the kill time. With switch 4 on, it is 100 msec longer than the kill time. This setting can be used for bikes that are prone to fall out of gear. (Switch 4 should normally be turned off.)
