Stage 2 AI Performance Chip Module OBD2 for Infiniti – Adaptive Power & Fuel Efficiency

Empower the Drive: Unleash Your Infiniti

Infiniti vehicles are born from a heritage of Japanese performance and innovation. Whether you drive the twin-turbo Q50 Red Sport, the technologically advanced QX50 with VC-Turbo, or the commanding QX80, your vehicle is designed to "Empower the Drive." However, factory ECU calibrations often prioritize soft luxury and fleet fuel economy over the raw, engaging performance that the chassis and engine are actually capable of delivering.

The Stage 2 SMARTTUNE with AI Technology is the sophisticated upgrade your Infiniti demands. This is not a generic tuning box; it is a high-speed, AI-driven OBD2 module that interfaces with your vehicle’s advanced powertrain management. It learns your driving style—whether you are commuting in Standard mode or attacking corners in Sport+—to unlock the responsive, exhilarating power that lies dormant in your factory software.

Optimized for VR-Series and VC-Turbo Performance

Infiniti’s engine technology is world-class, from the legendary VQ V6s to the modern VR30DDTT and the revolutionary Variable Compression Turbo (VC-Turbo). Our AI technology safely optimizes boost pressure, ignition timing, and fuel maps to bridge the gap between luxury cruiser and sports car.

• Awaken the Red Sport: The VR30 Twin-Turbo is a beast, but it can feel restrained in daily driving. We optimize the signal to provide up to 50% better throttle response, significantly reducing turbo lag and making the power delivery feel immediate and violent when demanded.
• VC-Turbo Precision: For QX50 and QX55 owners, the Variable Compression engine is a marvel. The chip optimizes the engine's performance map to ensure that when you need power, the transition is seamless and punchy, eliminating the "rubber band" feel often associated with CVTs.
• Commanding V8 Torque: The QX80 is a luxury fortress, but it's heavy. Gain up to 28.6 ft·lbs of added torque from the 5.6L V8, making merging, passing, and towing heavy loads feel effortless.
• Transmission Synergy: Designed to work in harmony with Infiniti’s 7-speed and 9-speed automatics. The chip ensures that shift points align with the increased power output, keeping the drive smooth yet responsive.

Universal Compatibility: From G35 to QX60

The Stage 2 SMARTTUNE utilizes the standard OBD2 port (standard on 1996+ models), ensuring compatibility with the full evolution of the brand.

• Models Supported: Q50, Q60, Q70, QX30, QX50, QX55, QX60, QX80, as well as the legendary G-Series (G35/G37), M-Series, FX, and EX models.
• Engine Tech: Fully compatible with VR30DDTT (Twin Turbo), VQ35/VQ37 (Naturally Aspirated V6), VC-Turbo (Variable Compression), and V8 powertrains.
• Adaptive Learning: The onboard AI processor analyzes your specific vehicle's sensor data over the first 200 miles, creating a custom map that enhances performance while respecting the vehicle's luxury demeanor.

100% Safe and Warranty Protected

Infiniti owners value reliability alongside luxury. The SMARTTUNE is engineered to be completely safe, non-invasive, and undetectable once removed.

• No Warranty Flags: The module does not "flash" or permanently rewrite the ECU. It operates as a live signal optimizer. To return to stock for a dealer service, simply unplug it. It leaves no digital footprint.
• Plug-n-Play Simplicity: No need to open the hood or cut wires. It installs in seconds via the OBD2 port located under the dashboard (usually on the driver's side).
• Reliability First: Engineered in the USA to operate within the safe mechanical limits of your engine, backed by a lifetime warranty and a 100% money-back satisfaction guarantee.

Frequently Asked Questions

Will this work on the Q50 Red Sport 400?
Yes. While the Red Sport is already high-performance, the Stage 2 chip sharpens the throttle response and optimizes the mid-range torque curve, making the car feel even more aggressive in Sport+ mode.

Is it safe for the VC-Turbo (Variable Compression) engine?
Absolutely. The AI recognizes the complex nature of the VC-Turbo engine and optimizes the fuel and timing parameters to complement the mechanical compression changes, not fight them.

Does it improve the CVT driving experience?
Yes. By increasing low-end torque, the chip reduces the need for the CVT to constantly rev high to find power. This results in a quieter, more "traditional" driving feel with less drone.

Will it affect my Drive Mode Selector?
No. The chip enhances the baseline performance. Eco mode will be more efficient, Standard will be smoother, and Sport/Sport+ will be noticeably sharper.
