from his opponents side of the Christmas tree, the delay box internally does simple math computations for the driver), bump up and bump down compensation (allows a driver to easily make small plus or minus timing adjustments quickly and remotely), crossover compensation (an offset time the driver can set when crossing over), safety interlock (prevents delay box from reactivating once the race car is in motion, a valuable feature), bypass (a feature where the delay box is deactivated before it can finish counting down, thus launching the car immediately), and other features. Controversial Use Delay box use was very controversial in the 1980s and 1990s, with the peak of controversy occurring around 1993-1994. This continues to this day but the controversy has dropped substantially from its peak. Delay box use became controversial because experienced racers lost some advantage they had enjoyed over the younger, less experienced rivals. Veteran racers who were against the use of delay boxes complained to race track owners and drag racing sanctioning bodies that the delay boxes were unfair. Delay box usage does give a less experienced driver reaction time accuracy improvements that more experienced racers took time and money to learn. These old time racers said that delay box usage constituted cheating. The term "cheater boxes" was heard at the drag races for many years. Track owners around the United States began creating separate races on the same race day at their facility by dividing racers into two groups or classes, a box class and no-box class. "Some" racers began concealing the delay box and entering the no-box class, therefore actually cheating. Delay box use was initially thought to be limited to transbrake equipped cars. Delay box use by motorcycle drag racers lagged far behind those in use by the car racers. These factors contributed to the delay box controversy because some racers felt their chosen equipment was incompatible with the use of delay boxes. This was untrue and educating the bracket racing community took time. A significant reason motorcycle drag racers lagged in implementing delay box electronics is due to the wide variety of driveline configurations on dragbikes. Of the successful bracket racing drag race cars, most had automatic transmissions equipped with transbrakes. Innovation quickly adapted the delay box to cars with dual line locks (devices which locked the brakes on all four wheels electrically), and manual transmissions with the use of a hydraulic
