System Description
Our WOT Shift (Ignition Cut) Module is an essential addition to any sequential transmission setup.  An accurate torque reduction during up-shifts at WOT or down-shifts under braking is required to get the most performance out of your sequential gear set.

Torque reduction is performed by programmatically cutting power by a specified % to the ignition coils during a shift event.  The dog-ring engagement (and disengagement) of a sequential transmission is dependent on the lightest torque reduction to perform the fastest shifts.

Our software provides the race engineer the ability to cut the ignition coil power by a given duration and/or percent based on the gear the transmission is shifting into.  (When the transmission is equipped with a gear position sensor.)

Closed-loop operation is available for sequential transmissions equipped with high resolution gear position sensors such as the Blade360.

Systems can be configured to integrate throttle blip on downshift as well.
