HKS Speed Defense Limiter

Eliminates Speed Limiter to drive over 180km/h

Most of JDM vehicles are equipped with speed limiter functions. 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 I does not rewrite the factory ECU data; the speed limiter can be eliminated without modification of the ECU data.

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.
