Some details on the awesome killbox itself.
Engine Kill Times are adjustable per gear shift. This is great for those with 1-2 or 1-2-3 Auto Transmissions, or those who may need to adjust kill time for added power down track. Adjustable Solenoid Advance Time allows the solenoid to apply pressure to the shift linkage before the engine kill sequence begins to allow faster shifts with less delay. Auto Shifting built right into the controller with no need for added boxes or chips. Can be wired to ground or +12v shift buttons for manual shifting. Works on any motorsports engine with a digital ignition (Not CDI) 1, 2, 3, or 4 Cylinders.
