HKS VAC Nissan GT-R R35

Computerized Full Computer for High Speed Driving

HKS VAC (Velocity Advanced Computer) is an electronic device designed to eliminate the vehicle's factory speed limiter to bring out full performance of the vehicle. With the HKS VAC, the high speed driving is possible without affecting the high performance. HKS VAC analyzes the control method for each vehicle; so it can eliminate the speed limiter by the most appropriate way for the vehicle

What is VAC?

Toyota and/or Lexus equipped with the 6 speed automatic transmission are controlled electrically; so the factory computer controls the vehicle precisely in response to various driving conditions. The conventional speed limiter elimination method may affect this precise control system; it cannot fully utilize the performance of the 6 speed automatic transmission. However, with HKS' unique technology to control this computerized 6 speed automatic transmission, the VAC can fully utilize the performance of the 6 speed automatic transmission. After the factory speed limiter was eliminated when the vehicle's speed reached over 180km/; then HKS VAC works as the full computer to control the automatic transmission.

HKS VAC also can be used on the vehicle with the CAN communication system. VAC can control the advanced and complicated in-vehicle network system, which even controls the vehicle's motion, by its original technique.

Main Features

• HKS conducted its own research on the CAN communication to control it. (CAN communication system is utilized by late models as the method to transmit the speed signal and other signals. It transmits more than 40 signals using only 2 communication lines.)
• VAC can pick up only the speed signal from various signals transmitted by CAN communication system to eliminate the factory speed limiter.
• There is no secondary negative effect after the factory speed limiter was eliminated.
• HKS VAC has the output line to convert the speed signal from CAN communication to the analog output. Therefore, the speed over 180km/h can be indicated by HKS Circuit Attack Counter or Turbo timer.

HKS electronic devices will provide the better driving performance and support for your vehicles.

You will need electronic control devices and software settings for the ultimate tuning performance. The electronic control devices will control the vehicles in a higher level for the best total tuning performance. Modern vehicles are equipped with sophisticated software that controls the vehicles and HKS provides easy to use for beginners and also provide supports for professional tuners.
