Just to clarify, the Wotbox is a device on the market that you wire to a clutch switch, to cut the ignition when the clutch is depressed. It is designed for full throttle shifts. You hold the pedal to the floor, and the ignition cuts out slightly during shifts similar to a two step to prevent over-revving or the need to lift off the throttle. Claims to be able to be wired into any ignition system.
Thinking about trying one on the Belv, but curious if anyone on here has any feedback from expereience with one.
