HKS Speed Limit Defender

HKS Speed Limit Defender
Most JDM vehicles are equipped with a 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.

Cars with a CAN communication system
Lately, some vehicles are equipped with "CAN Communication System" 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.

HKS SLD type III does not rewrite the factory ECU data; the speed limiter can be eliminated without modification of the ECU data.

SLD III Features

HKS found the way to pick up the speed signal from other signals transmitted by CAN communication system to eliminate the speed limiter.

The original control method of CAN communication system enables the vehicle's digital speed meter to indicate the speed over 180km/h.

The speed limiter can be eliminated even after rewriting the ECU program to connect the unit to the ECU harness.
