Nissan Emulator – Infiniti X-Trail Almera Altima Skystar Sunny PathFinder Maxima NATS5 A & B Type IMMO Emulator Simulator

What it does (in simple terms)

This device simulates the factory NATS5 immobilizer signal, so the engine ECU thinks the original key/immobilizer system is present and authorized.

In practice, it is used to:

• Replace a faulty immobilizer system (ECU/BCM/IMMO failure cases)
• Allow engine start when original NATS module is damaged or missing
• Used in ECU swaps or engine conversions (when properly matched)
