HKS Speed Defense Limiter
Fits Most Models
4502-RA002
Overview:
The HKS Speed Defense Limiter (SLD) is a specialized performance device designed to remove the factory-installed speed limiter found on most Japanese Domestic Market (JDM) vehicles. Many JDM cars are electronically restricted to a top speed of 180 km/h, limiting their full performance potential. With the HKS SLD installed, you can safely unlock your vehicle’s true speed capabilities and enjoy driving beyond this factory limit.
Ideal for enthusiasts who want to maximize their vehicle’s performance without modifying the ECU data, the HKS SLD works seamlessly with modern CAN communication systems. This ensures compatibility with a wide range of models, including those with advanced digital speed control technologies.
Key Features:
The HKS Speed Defense Limiter offers advanced technology and user-friendly installation to enhance your driving experience. Key features include:
- Eliminates the factory speed limiter, allowing speeds over 180 km/h.
- Compatible with most JDM vehicles equipped with speed limiters.
- Utilizes a unique method to intercept speed signals transmitted via CAN communication systems.
- Maintains accurate digital speedometer readings beyond the original speed limit.
- Does not require rewriting or modifying the factory ECU data (Type I version).
- Works even if the ECU program has been rewritten, by connecting directly to the ECU harness.
- Supports vehicles with modern CAN communication speed control, overcoming previous limitations.
- Preserves vehicle reliability and factory settings while unlocking full speed potential.
Construction & Design:
The HKS Speed Defense Limiter is engineered with precision to integrate smoothly with your vehicle’s existing electronic systems. By tapping into the CAN communication network, it intercepts and modifies speed data signals without altering the ECU’s core programming. This innovative approach ensures a clean installation that respects the vehicle’s original design and electronic architecture.
Its compact design allows for straightforward connection to the ECU harness, minimizing installation complexity and maintaining factory integrity. The device is built to withstand automotive environments, ensuring durability and consistent performance over time.
Installation & Fitment:
The HKS SLD is designed for easy installation on most JDM vehicles equipped with factory speed limiters. It connects directly to the ECU harness without the need for ECU data rewriting or complex tuning procedures. This plug-and-play approach means no cutting, drilling, or special modifications are required.
- Simple connection to the ECU harness.
- No ECU data modification necessary for Type I units.
- Compatible with vehicles using CAN communication speed control systems.
- Maintains factory speedometer accuracy beyond 180 km/h.
