Ecotune Stage 3 Software – Overview, Gains & Hardware Requirements

What Is Ecotune Stage 3 Software?

Ecotune Stage 3 Software is an advanced performance calibration designed for vehicles equipped with significant hardware upgrades that allow for major increases in airflow, fueling capacity, and thermal efficiency.
Unlike Stage 1 or Stage 2, which operate within the limits of mostly factory components, Stage 3 is engineered to maximise the potential of upgraded turbochargers and supporting systems.

Stage 3 software delivers:

• Substantial increases in horsepower and torque

• OE  turbo spool and improved power delivery depended on Turbo Charger

• Optimised boost control, ignition timing, and fueling strategies

• Enhanced high-RPM performance

• Improved efficiency under load with proper supporting hardware
  
  

All Stage 3 calibrations are developed and validated by the Ecotune Calibration Team to ensure maximum performance with safe, reliable operation.

Expected Performance Gains

Note: Actual figures vary by platform, turbocharger size, hardware fitted, fuel type, and overall vehicle condition.

Typical Stage 3 improvements may include:

• +80 to +200+ horsepower over Stage 1 depending on turbo size
  
  

• +100 to +250+ Nm torque
  
  

• Higher sustained power at high RPM due to improved compressor and turbine efficiency
  
  

• Sharper throttle response and enhanced mid-range punch
  
  

• Increased top-end power where factory turbos restrict performance
  
  

Final gains are determined during calibration sign-off once all hardware is confirmed and vehicle health is verified.

Mandatory Hardware Requirements for Stage 3

To support the increased airflow, heat management, and fueling demand, the following upgrades are required or strongly recommended:

Turbo & Airflow System

• Upgraded turbocharger (hybrid, big-frame, or platform-specific unit)
  
  

• High-flow cold air intake
  
  

• Turbo inlet pipe / high-flow turbo ducting
  
  

• Front-mount or upgraded intercooler
  
  

• High-flow charge pipes (platform dependent)
  
  

Fuel System Upgrades

Depending on the platform:

• Upgraded Low-Pressure Fuel Pump (LPFP)
  
  

• Upgraded High-Pressure Fuel Pump (HPFP)
  
  

• Larger / high-flow injectors
  
  

• Optional: ethanol-compatible fuel system components if running E85 blends
  
  

Exhaust & Flow Components

• High-flow downpipe (sport cat or decat – where legal)
  
  

• Upgraded exhaust system supporting increased flow
  
  

• Optional: larger intercooler outlets or boost pipes
  
  

Additional Recommended Components

• Oil catch can or PCV upgrades
  
  

• Upgraded engine mounts (platform dependent)
  
  

• Performance clutch or upgraded DSG/TCU software for higher torque applications
  
  

• Improved cooling (oil coolers, radiator upgrades) for high-stress use
  
  

Ecotune Stage 3 Pre-Tune Requirements

Your vehicle is booked for Ecotune Stage 3 tuning.
Before any calibration work begins, a full pre-tune inspection must be carried out. This inspection is essential for several reasons:

1. Safety & Reliability – Stage 3 software places significantly higher demands on the engine, fuel system, and supporting components. The inspection helps confirm where possible that the vehicle is in suitable mechanical condition and safe to tune at this level. 

2. Correct Hardware Verification – Stage 3 calibrations are designed to work with specific performance hardware. Incorrect, faulty, or incompatible parts can lead to poor performance or serious engine damage.

3. Ensuring Accurate Calibration – Knowing exactly what hardware is fitted allows the Ecotune Calibration Team to build or select the correct software version, ensuring optimal power delivery, drivability, and reliability.

4. Preventing Avoidable Issues – Discovering problems before tuning prevents wasted time, unnecessary costs, and potential mechanical failures once the car is operating under increased load.
   
   

As part of the pre-tune process, we must confirm all performance hardware fitted to the vehicle, including but not limited to:

• Turbocharger
  
  

• Cold air intake system
  
  

• Turbo inlet pipe
  
  

• Low-pressure fuel pump (LPFP)
  
  

• High-pressure fuel pump (HPFP)
  
  

• Upgraded injectors
  
  

• Intercooler, downpipe, exhaust components, or any other performance-related modifications
  
  

This information ensures the calibration matches the vehicle’s exact setup.

Software Approval Requirement

All software must be reviewed and signed off by the Ecotune Calibration Team.
The vehicle will not be released in a tuned state until this approval process is completed.

If the customer insists on taking the vehicle before calibration sign-off is complete, the vehicle will be returned to stock software prior to release.

Stage 2 - Although not a requirement we do recommend a Pre-Tune inspection on Stage 2 tuning also.
