Description

Most JDM vehicles are equipped with a unfortunate speed limiter function. With this function, the vehicle’s speed cannot exceed 180km/h. On the other hand, the performance of JDM vehicles have increased significantly; even non-sports models are capable of driving over 180km/h. The HKS Speed Limit Defencer for a GT-R can eliminate the factory speed limiter to drive over 180km/h and bring out full performance of the vehicle.

Fitment:

• 2008- GT-R VR38DETT

Kit Includes:

• VAC Main Unit
• Relay Harness
• ON/OFF Switch

Features:

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. 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.

• 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.

Performance:

• Speed Limiter Cancellation
  VAC can cancel the factory default speed limiter function at 180km/h.
• Speed Signal Option Output
  Speed pulse signal (4-pulse) can be detected from the light blue wire of the Relay Harness, so the speed can be indicated by the meter such as HKS Circuit Attack Counter.
• Speed Limiter ON/OFF Switch
  The provided ON/OFF Switch is to turn on and off the VAC. It is not necessary to install this switch to cancel the factory speed limit.
• Speed Display
  Speed over 180km/h can be displayed by the factory meter, and multi function meter.
