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

Urban Mobility, Maximized

The Smart car is a triumph of packaging and urban efficiency—a vehicle designed to conquer the concrete jungle with unique style and impossible parking capabilities. Whether you drive the original 450, the Mitsubishi-powered 451, or the modern 453, your Smart is the ultimate city tool. However, the factory tuning often leaves drivers frustrated. The automated manual transmissions can feel jerky and slow to react, while the electronic throttle often suffers from a dangerous "dead pedal" delay that makes pulling into traffic stressful.

The Stage 2 SMARTTUNE with AI Technology is the upgrade that makes your Smart drive as cleverly as it was designed. This is not a simple resistor; it is a sophisticated, AI-driven OBD2 module that interfaces directly with your Smart’s MEG/Bosch engine management system. It learns your driving style—whether you are darting through city traffic or maintaining momentum on the highway—to unlock the responsive, zippy performance that the factory software suppresses.

Optimized for 3-Cylinder Turbo and NA Performance

Smart engines are small engineering marvels, often engineered by Mercedes-Benz, Mitsubishi, or Renault. Our AI technology is specifically calibrated to maximize the potential of these 3-cylinder powerplants, addressing their specific weaknesses.

• Fix the Shift Lag: The number one complaint with Smart cars (especially the 451 and 450) is the slow, lurching automated manual transmission. By optimizing the engine's torque request during shifts, the SMARTTUNE helps smooth out gear changes, significantly reducing the "head bob" effect and making acceleration linear.
• Turbocharged Zip: For the 0.9L and 1.0L Turbo models (including Brabus), the lag off the line can be annoying. We optimize the signal to provide up to 50% better throttle response, giving you instant boost for quick lane changes and confident merging.
• Highway Confidence: Merging onto a highway in a Smart can be intimidating. Gain up to 28.6 ft·lbs of added torque (relative to engine size), which is vital for maintaining speed on inclines and passing trucks without needing to floor the pedal constantly.
• Twinamic Dual-Clutch: For newer 453 models with the Twinamic DCT, the chip sharpens the shift logic in Sport mode, making the car feel surprisingly athletic and eager.

Custom Programmed for Your Specific Smart

This module utilizes the OBD2 port to detect your vehicle's specific VIN and powertrain profile. It applies the correct mapping adjustments tailored to your exact generation.

• Models Supported: Specifically calibrated for Fortwo (450/451/453), Forfour (454/453), Roadster (452), and Crossblade.
• Engine Tech: Automatically detects and adjusts for the 0.6L/0.7L Suprex Turbo, 1.0L Mitsubishi (NA/Turbo), and 0.9L Renault TCe engines.
• Adaptive Learning: The onboard AI processor analyzes your specific vehicle's sensor data over the first 200 miles, creating a bespoke map that maximizes city agility while smoothing out the drivetrain quirks.

100% Safe and Warranty Protected

We understand that Smart cars have unique engineering. The SMARTTUNE is engineered to be completely safe, non-invasive, and respectful of your vehicle's electronics.

• 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 remove the engine cover or access the tight engine bay. It installs in seconds via the OBD2 port located under the dashboard (usually near the steering column or fuse box).
• Reliability First: Engineered 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 stop the jerky shifting on my 2012 Fortwo?
While it cannot change the mechanical design of the transmission, optimizing the throttle and torque delivery significantly smoothes out the shifts. The "lull" between gears is reduced because the engine recovers power faster.

Is it safe for the Brabus edition?
Yes. The Brabus already has a sportier tune, but the Stage 2 chip sharpens it further, optimizing the boost curve for even more mid-range punch and responsiveness.

Will it help my Smart car go faster on the freeway?
It won't increase the factory speed limiter (governor), but it will help you get there faster and, more importantly, help you maintain that speed when hitting hills or headwinds without the car feeling like it's struggling.

Does it work on the Electric Drive (ED/EQ) models?
Yes. For electric models, the chip optimizes the torque request signal from the pedal, making the acceleration feel more linear and aggressive in "Sport" modes, though it does not add horsepower to the electric motor itself.
