HKS VAC (Velocity Advanced Computer) is an electronic device designed to eliminate the vehicles 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
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 vehicles 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 vehicles motion, by its original technique.
Most of JDM vehicles are equipped with speed limiter function. With this function, the vehicles speed cannot exceed 180km/h. On the other hand, the performance of JDM vehicles is improved; even non-sports models are capable of driving over 180km/h.
HKS SLD can eliminate the factory speed limiter to drive over 180km/h and bring out full performance of the vehicle.
Lately, some vehicles are equipped with "CAN Communication System" (*1) to control the vehicles speed. This CAN communication system complicates elimination of the speed limiter. However, HKS SLD type III utilizes a new method to control the speed data in CAN communication system and eliminate the speed limiter.
HKS SLD type III does not rewrite the factory ECU data; the speed limiter can be eliminated without modification of the ECU data.
*1 CAN (Controller Area Network) communication is a high speed, highly reliable, and internationally - standardized network system within a vehicle. It controls the engine, drive-train and meters, etc. Also in addition to the speed data, it controls electric devices. CAN requires only 2 lines to control data. CAN is very popular in Europe and is becoming more popular globally.
Cooling by Radiator fan control" and "Speed limiter elimination." These are recommended to do before driving a circuit, and these were easily implemented before; however, the CAN communication system makes them difficult.
Using an HKS original management system, it controls the CAN communication signal. Through this, the radiator fan can be controlled, preventing water temperature increases beforehand and safe-guarding the engine. The FSC is also equipped with a speed-limiter cut function, allowing the user to enjoy stress-free track racing even at high speeds.
HKS Fan and Speed Controller (FSC) is a lightweight and compact size device equipped with functions necessary for circuit/track racing.
