The Dyna Shift Counter is the missing link of the chain of systems on a drag bike. The Shift Counter provides the proper interaction between the air shifter system, the ignition system, the transmission, and other systems.
Shift Counter Features:

  • Built-in programmable electronic shift kill (replaces failure prone, not easily adjustable, mechanical air kill switches) Includes 1-2 auto, 1-2-3 auto and 1-2-3-4 auto modes.
  • Shift kill can be set at 20, 30, 40, 50, 60, 70, 80 or 90 milliseonds
  • Automatically control semi-automatic transmission kill sequences.
  • Gear selector outputs allow you to control other devices according to current gear selection. You can activate multi-stage nitrous systems, waste gates, fuel systems, timing control, or anything else according to transmission gear.
  • Plugs right into the Dyna 4000 Pro ignition kill input (and can be used with other ignitions)
The Shift Counter consists of a small box, approximately 3" x 2.5" x 1", with six screw terminals on one end. Above each screw terminal is an LED lamp to indicate which terminal (or gear) is active. When a terminal is active, it is a source of 12 volts which can be used to activate other devices. The Shift Counter must be used in conjunction with an electric switching valve on the air shift system (electric over air setup - sold on pages 38-39). The Shift Counter trigger input is connected to the handle bar electric shift button. When the electric shift button is pressed, the Shift Counter is triggered and rotates it's outputs to the next gear. At the time of the 1-2 shift, the Shift Counter will deactivate the 1st gear screw terminal and activate the 2nd gear terminal. During the shift the Shift Counter will generate a shift kill pulse of the selected duration to kill the ignition during the shift. The shift kill duration is adjustable between settings of 20, 30, 40, 50, 60, 70, 80 or 90 milliseconds. When the Shift Counter is used on a vehicle, an air kill switch is no longer necessary. The Shift Counter will continue to function similarly each time the shift button is pushed, rotating it's outputs on each successive shift until the vehicle is in high gear. The Shift Counter has four shift kill modes which are user selectable: 1-2 auto kill mode, 1-2-3 auto kill mode, 1-2-3-4 auto kill mode and full manual mode. The auto mode eliminates the headaches associated with the task of setting up the kill for a semi-automatic transmission.
