ED-O
Electronic Coilover Suspension System This product is a vehicle-specific electronic coilover suspension system designed to directly utilize the factory electronic damping connectors without modifying the original vehicle wiring harness, ensuring full compatibility with the OEM electronic control system.
While upgrading to a performance suspension setup, the factory electronic damping adjustment functions can still be fully retained, allowing drivers to enjoy enhanced handling performance while maintaining the convenience of the OEM comfort and driving mode adjustments.
The suspension features a high-strength monotube design with adjustable ride height, allowing precise setup based on different road conditions and driving preferences.
he damping system is equipped with a top-mounted adjustment mechanism offering 36 levels of damping adjustment, enabling fine tuning of suspension stiffness for street driving, mountain roads, and aggressive performance driving applications.

Electronic Damping Suspension Technical Overview
This product retains the vehicle’s OEM electronic control system (current-controlled valve) while optimizing the internal mechanical damping structure of the damper. As a result, overall chassis control performance is significantly improved beyond factory settings.
PRODUCT FEATURES
- Compatible with OEM electronic damping systems.
- Direct plug-and-play factory connector design.
- Retains OEM electronic drive mode functions.
- Adjustable ride height.
- 36-level damping adjustment.
- Balanced comfort and handling performance.
- Suitable for both street and performance driving applications.
FIGURE A — OEM DAMPER CURVE
Figure A shows the adjustment range of the factory electronic damping system. Since the factory system provides only a relatively weak current signal, adjusting the suspension stiffness through the OEM control system results in an actual damping change of only approximately 5%–10%. This difference is so small that it is barely noticeable to the driver.
For the same reason, even if our shock absorbers with electronic damping adjustment are installed, the actual damping range controlled by the factory system would remain similar to the OEM setup. As a result, the difference in stiffness would still be very difficult to notice.

FIGURE B — UPGRADED COILOVER DAMPER CURVE
In Figure B, the blue line represents the adjustment range of the factory electronic damping system, while the red line represents the damping adjustment range of our shock absorbers when adjusted manually.
FIGURE C — EDN REMOTE RESERVOIR DAMPING CHARACTERISTICS
Figure C demonstrates our patented technology. This technology retains the factory electronic damping control function while also providing a significantly wider range of damping adjustment, allowing for much greater changes between softer and firmer settings.
