Ecotune Software Stage 3 - S4/S5 B9 Hybrid

The Ecotune Stage 3 software for the Audi S4 and S5 B9 (3.0 TFSI) is an elite calibration designed for vehicles equipped with major hardware changes, specifically high-flow hybrid turbochargers. This calibration bridges the gap between raw engine power and refined road performance, allowing your B9 platform to reach its highest potential. By optimizing boost control, ignition timing, and fuel delivery, this software ensures your vehicle delivers supercar-slaying performance while maintaining the safety and reliability required for long-term health.

Key Software Features

• Massive Power Increases: Typical gains of +80 to +200+ horsepower over Stage 1, depending on turbo selection and fuel quality.
• Monster Torque Gains: Experience an additional +100 to +250+ Nm of torque for relentless mid-range pull.
• Optimized Turbo Spool: Specifically calibrated to improve the response and "start-up" of larger hybrid units.
• High-RPM Stability: Calibration maintains peak power delivery all the way to the redline, overcoming factory turbo limitations.
• Reflex Response Logic: Advanced real-time monitoring of engine vitals to adjust for fuel quality and environmental factors.

Categorized Hardware Requirements

To safely achieve Stage 3 performance levels, your Audi B9 requires a structured hardware stack. We recommend and supply components from our preferred partners:

1. Turbo & Airflow

Optimized for hybrid units from TTE or Garrett. Requires high-flow induction from Forge, Racingline, or APR. Cooling is mandatory via do88 or APR intercoolers.

2. Exhaust & Downpipe

Large-bore, high-flow downpipes are strictly required to manage backpressure. We recommend Scorpion or Milltek.

3. Fuel System

Upgraded fueling is essential for high-boost applications, including upgraded HPFP and LPFP solutions. Flex Fuel capabilities are supported when configured with the appropriate sensor hardware.

4. Additional Recommended Upgrades

To handle the massive torque increase, we strongly suggest Racingline engine mounts. We exclusively use Millers Oils and Motul high-performance fluids for all Stage 3 builds.

Vehicle Compatibility & Applications

This software is developed for the 3.0 TFSI V6 engine found in the Audi B9 platform. Various hose and hardware colour options are available for induction components.
