The GP System (Japanese: GPシステム, Jīpī Shisutemu) is a series of lap-detection systems released by Tamiya in July 2001.
They were designed for both the Dangun Racers and the Mini 4WD cars.
General info
The original GP System full set, which was originally designed for Dangun Racer, includes a receiver, the antenna components, an AC adapter, a pair of noise filter, a mini CD contains the lap-detection software and a set of Dangun Racer GP Chips (5 pairs of the GP Chips at different bands). For Mini 4WD car use, the separate GP Chips for Mini 4WD car are required.
As the cars contains the GP Chip pass through either the loop anntena (for Dangun Racers) or the straight anntena cable (for Mini 4WD cars), the system will detect it via the GP Chips in the cars and sending the data to the connected PC.
Although innovative, there are three major problems with this system. The cost of the both the GP System full set and the GP Chip set for Mini 4WD car (which was about 165,000 yens in total), a PC is required to make the system works, and the fact that the GP System software can only runs on PC with Windows 2000 and below. (The last one being a major problem due to the release of newer Windows OS) Because of these, the GP System and the GP Chip sets were later discontinued.
