GPS POWER TEST BOX

．Vehicle Application: Universal
．Compatible App: K Race (for iOS & Android)

The GPS Power Test Box is a powerful and affordable vehicle performance measurement tool that uses a high-performance satellite positioning chip combined with low-energy Bluetooth transmission to exchange data and control with mobile phones.
The GPS Power Test Box provides 18Hz high-precision satellite positioning data. Through data screening and filtering algorithm estimation, the straight-line acceleration measurement time error is reduced to within 100 milliseconds, making it a simple performance measurement tool.
K Race is a data monitoring tool that assists car and motorcycle drivers in vehicle tuning.
By connecting to the KOSO GPS Power Test Box via Bluetooth, vehicle data can be monitored very efficiently.
Because the KOSO GPS Power Test Box has a built-in high-efficiency GPS and gyroscope module, it can record data at a very high frequency interval, so it can provide very accurate and effective values.
Compared with other Apps that only use mobile phone GPS data, its data will be much more accurate.
The straight-line acceleration mode is used to observe the performance of the vehicle during the acceleration process as reflected by parameter changes.
The dynamometer mode provides a simple measurement tool to understand the wheel horsepower changes during acceleration.
The performance calculator provides simple calculation tools to understand the theoretical limit of vehicle performance through basic value input.

- Origin -
KOSO was officially born out of the realization that an independently developed brand is indispensable for future market marketing. Therefore, KOSO was registered as a trademark of Tong Ya in 1989. KOSO is derived from the Japanese words "Concept" and "High Speed". Concept represents creativity, while High Speed represents high-performance expression—combined, it expresses the hope that the company can use creativity to create high-performance products!

- Spirit -
The brand spirit that KOSO pursues is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently hold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone.



- Brand Journey -
Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly spurs itself on by improving its own technology. We firmly believe that brand image and product quality are synonymous! Therefore, the company has strict requirements for product development, production processes, and quality control, hoping to achieve the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, and hopes to become the next world number one from Taiwan within ten years, another pride of Taiwan, and the pride of Taiwanese people.

- Exhibitions and Certifications -
Tong Ya Electronic has been exhibiting in Italy since 2001, gradually stepping onto the international stage, bringing KOSO's dedication and professionalism to the world, and striving to convey an image of high quality and innovation. It obtained TS16949 international certification in 2007, and ISO 14001 and ISO 45001 international certifications in 2024. In the future, it will create more moving products. Every product launch requires actual installation testing, which is the strictest quality inspection method. No matter how well a product is designed, once it is actually installed and used, it is a test of quality. In order to further improve quality and actual product testing, we participate in international competitions. However, every award is an affirmation of the product, because it is a modification and installation that does not allow for mistakes. We are so rigorous about quality. Test reports and product measurement charts are also our demonstration of the results of customer installation. It is precisely because of this caution that our products can show better quality time after time.




- Equipment and Checkpoints -
Our pre-inspection for every product uses the most advanced technical machinery, setting different conditions to simulate and conduct tests, such as vibration tests, waterproof tests, etc. All commissioned partner manufacturers who have participated in the inspection process agree with our principles of quality control and trust the test results. What is rare is that under the test of the product like passing levels, we also add different conditions and make adjustments based on the actual environment, combined with user-friendly operation to present the most realistic test of the product and the quality improved after correction.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.
