From the website: • HM Quickshifter SUPER LITE has 3 setting for sensitivity with a fixed ignition kill time, so you can control how you use the gearbox and how you want the HM Quickshifter to work / feel. The load cell sensitivity is adjustable (amount of pressure it takes to activate). From the manual: The HM Super Lite is already set up for your motorcycle. If however, you would like to fine tune the quickshifter then this is easily achieved via the LED signals emitted at power-up. The setting that can be adjusted on the HM Super Lite is LOAD SENSITIVITY, which has 3 settings. When the HM Super Lite is powered up, it indicates the setting once by flashing the LED: 1 blip: Low Sensitivity 2 blips: Medium Sensitivity 3 blips: High Sensitivity When looking through their website, it looks as though you order the the super lite for the specific bike you are using it for. I would only assume they test the bikes and see what kill time is most effective for each application. It also appears they make them with adjustable kill times, but they are closer to the $500+ range. What bike are you going to use as the test subject?
