"Precision Speedometer Conversion for IVA Compliance"


---

Japan Import's speedometer unit is designed to integrate seamlessly with your vehicle's existing systems. The process involves hard wiring the unit directly into the vehicle's electrical system, ensuring a stable and reliable connection that's essential for accurate speed readings. This method bypasses the need for unreliable adapters or temporary solutions, providing a permanent fix that's both efficient and effective.

However, it's crucial to understand that fitting a chip to modify the wiring loom can have unintended consequences on your vehicle's automatic gearbox. Such modifications can disrupt the communication between the gearbox and the Electronic Control Unit (ECU), leading to suboptimal performance. The gearbox may not shift gears at the correct speeds, and in some cases, it could even cause the ECU to misinterpret signals, resulting in erratic gearbox behavior.

To avoid these issues and ensure your vehicle passes the Individual Vehicle Approval (IVA) inspection, it's advisable to use a standalone speedometer service. This service will provide a dedicated speedometer conversion that complies with UK regulations, displaying speeds in miles per hour (mph) and ensuring the accuracy required for the IVA inspection⁷. By choosing this service, you can maintain the integrity of your vehicle's systems and avoid the potential pitfalls associated with chip modifications.
