Gizzmo's launch interface integrates with the Gizzmo Tach Recall Shift light to enable the fully adjustable launch control function. The launch control function induces sequential misfire events at the desired RPM set by the user.

In a turbo application, having the throttle open while inducing misfire increases the velocity and density of exhaust gases, and in doing so allows the turbo to spool up and generate boost without load. This results in boost being generated before launching, therefore allowing a vehicle to launch with considerably more power. The launch interface is activated by the engagement of the clutch and therefore allows flat shifting (the ability to change gears without removing your foot from the throttle). With the clutch engaged the RPM will pull back to the launch RPM previously set by the user in order to avoid over-revving. This allows the engine to remain in boost while moving through the gears.
Launch control can benefit naturally aspirated cars by giving a consistent launch RPM for the best result every time, and enable quicker gear changes through flat shifting.
