A two-stage time operated throttle and method is described for use on a drag racing vehicle comprising: (i) an electro-mechanical controller for selectively opening and closing the throttle of the vehicle; (ii) an on-board processor capable of issuing an open throttle control signal and a close throttle control signal; (iii) a first adjustable timer set prior to launch to a predetermined first value whereby, upon expiration of the first value, a close throttle signal is issued; (iv) a second adjustable timer set prior to launch to a predetermined second value, which is greater than the first value whereby, upon expiration of the second value, an open throttle control signal is issued; and (v) a signal for modifying at least one of the first and second values subsequent to launch based on actual race conditions. A four-stage time operated throttle and method is also provided by adding a third timer and a fourth timer. Additionally, a signal for modifying the values in the third and fourth timers can also be issued to permit maximum adjustability.
