I talked to a few companies who make quick shifter systems that automatically calculate kill times and asked about manually setting kill times per gear. They said it's possible to do, but they don't because with the system automatically calculating the kill time you'll get a more accurate kill time vs setting it manually. Just set the minimum kill time at max RPM and it will take care of the rest for all your shifts.

Cordona has essentially the same setup with a couple extra features, but you make all the adjustments using their onboard controls,it has a larger sensor, it costs $140 more, and it's a much larger controller.

How big the controller is compared to a credit card:
