The Woolich Racing Quickshifter allows shifting up through the gears without using the clutch by momentarily cutting the engine by either killing the ignition and/or stopping the delivery of fuel. Cutting the engine stops torque production allowing gear changes to be made without needing to use the clutch, and can minimize wear on the gearbox. Setting up a Quickshifter correctly requires installation of the hardware onto the bike as well as configuring the Quickshifter inside the Woolich Racing Tuned software (WRT) and finally writing the new settings to the ECU.
Each Quickshifter has it's own specific installation manual for connecting to the specific model of bike, these are found on the User Guides & Installation Manuals page.
The Race Tools configuration is started by clicking on the Race Tools button as shown below:

Configuration of the Quickshifter involves the following steps:
- Place a tick in the 'Enable Quickshifter' checkbox
- Clearing this checkbox disables the Quickshifter
- Select your Shift Direction
- This enables you to choose between bikes with a normal shift pattern and those with a reverse (race) shift pattern
- Set the Activation Pressure
- The Activation Pressure is the minimum pressure required to initiate an engine cut during gear shifting
- The default setting is 3 and this works well for most bikes
- Reducing the number requires less pressure to activate (1 is the softest setting)
- Increasing the number requires higher pressure to activate (10 is the hardest setting)
- Set the 'Delay Between Shifts'
- The 'Delay Between Shifts' is the minimum time between engine cuts in milliseconds
- This is referred to as 'Next Shift Delay' in some prior versions of Race Tools
- After the Quickshifter sensor is triggered the engine is cut and the bike shifts up a gear. The sensor will not trigger another engine cut until the 'Delay Between Shifts' has elapsed.
- Using a value under 100ms will result in a higher risk of a ‘double cut’ where the engine will cut twice in a row.
- The default is 300 ms
- Ignition Cut and Fuel Cut
- On some models it is possible to choose to use an Ignition Cut and/or Fuel Cut as shown below for a 2020 Honda CBR600RR
- At least one of these options MUST be selected for the Quickshifter to function. If neither is selected then the engine will not be cut during shifting, risking damage to the gearbox.
- Selecting Ignition Cut will kill the ignition when the Quickshifter is activated. If Ignition Cut is not selected, the spark plugs will still spark inside the cylinders.
- If Fuel Cut is selected, then fuel will not be injected into the cylinders during the engine cut. If Fuel Cut is not selected, then fuel will still be injected into the cylinders even if there is no spark.
- Selecting Ignition Cut with no Fuel Cut can potentially increase pop and bang during shifting
- The Quickshifter will only function if at least one of these options is selected.
Quickshifter Maps
Quickshifter maps display the engine cut times in milliseconds used for each gear shift dependent on engine RPM (row titles) and throttle position sensor (TPS, column titles).

If you click the ‘Gear’ dropdown menu, you can select the gear transition that you wish to view the cut time map for. The ‘Gear Unknown’ map is used when the ECU cannot determine which gear the bike is currently running in.
These maps can be used to make fine adjustments to the Quickshifter performance to achieve smooth shifts for different conditions. The preset values have been carefully set for each model of bike so care should be taken when making changes to these maps.
