Electronic Timing and Scoring

The Delaware Speedway timing and scoring system is made up of a scoring "loop" on the front straight located one car length back from the start finish line which is connected to a computer in the broadcast tower run by racing operations. Each vehicle is equiped with a small pager-sized device which emits a radio signal that is detected by the cable loop in the front stretch and relayed to the computer.

DelaNET
The laptop which runs the AMB timing and scoring software is connected to the public wifi network called DelaNET. Its connection allows spectators and teams to connect to the timing feed by laptop, smartphone, or tablet devices.

Installation
The electronic timing and scoring system was installed during the 2009 season at an estimated cost of $20,000. The first tests of the system took place during private rentals. Staff training on the new software began on practice day and the system was in use for the first race of the season.

Photo Finishes
For a number of reasons including those below, in weekly divisions only race officials aided by video replay and other methods are able to officially designate a race winner.

Transponder Location Varience: In most divisions at the speedway transponders do not have a standardized measurement location. This means that the location of a transponder can vary on different vehicles with a varience of several inches to potentially a few feet. As such the scoring transponders are not reliable during a photo finish as the transponder on one vehicle may be different then on another.

Total Time Varience: because of this varience in location, it has been proven technically possible for the "total time" of a second place competitor to several hundredths or thousandths of a second "faster" then the offical winner of the event. The reason for this is software related - - the total time begins counting when the computer operator activates the green flag function, not when the vehcile crosses the start / finish line on the initial start.

Designated Location: In selected series who have the resources to regulate transponder location, such as the NASCAR Canadian Tire Series the official winner can be determined based on the transponder times.

2012 Repairs
The transponder loop on the front straight was temporarily rewired with the assistance of officals from the NASACAR Canadian Tire Series during the 2012 Keystone Light 200 after the loop failed during qualifying for the event causing a delay in qualifying. The repairs were made permanent in the weeks following the race.
