View Frequently Asked Questions Here

Most of JDM vehicles are equipped with speed limiter function. With this function, the vehicle's 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.

For CAN Communication System

Lately, some vehicles are equipped with "CAN Communication System" (*1) to control the vehicle's 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.

No ECU Data Modification

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.
