IE Performance ECU Tunes for Audi B9 3.0T S4, S5, & SQ5

Unlock the performance potential of your Audi with the Integrated Engineering (IE) B9 3.0T Performance ECU Tune, designed for compatible Audi S4, S5, and SQ5 models equipped with the supercharged-by-turbo? 3.0L turbocharged V6 engine. Developed to optimize the factory engine calibration, IE tuning delivers stronger acceleration, sharper throttle response, and increased horsepower while maintaining everyday drivability through application-specific software.

The IE tuning platform offers a progressive upgrade path, with Stage 1 and Stage 2 calibrations for vehicles retaining the factory turbocharger and Stage 3 options for compatible upgraded turbocharger systems. Depending on the selected configuration, fuel, and supporting hardware, IE advertises output of up to 446 HP with Stage 1, up to 613 HP with Stage 3, and up to 739 HP with Stage 3 Plus.

Using the IE POWERlink tuning platform, drivers can access supported tuning functions through compatible mobile devices. Available features include adjustable throttle response, fuel calibration options, diagnostic functions, and controls for supported exhaust and launch features. Select functions can also be accessed through compatible Apple CarPlay integrations, widgets, and Siri controls.

For enthusiasts seeking additional performance, IE offers TrueFlex ethanol tuning, designed to adjust supported engine parameters according to the ethanol content of the fuel. Compatible upgraded turbocharger configurations can further expand the platform's power potential when paired with the required intake, intercooler, downpipe, fuel-system components, and appropriate tuning software.

The tuning suite also includes AutoProtect, which is designed to monitor critical engine operating conditions and reduce power when necessary. Additional available features include Exhaust Crackle, exhaust flap control, adjustable throttle response, Anti-Lag, and Rolling Anti-Lag, subject to the selected software package and vehicle compatibility.

Manufactured by Integrated Engineering, this tuning platform provides a flexible solution for Audi S4, S5, and SQ5 owners looking to develop a performance-focused street or track build.

ECU Tuning Stages

Stage 1 ECU Tune

The IE Stage 1 calibration provides an entry-level performance upgrade for compatible Audi 3.0T vehicles retaining their factory turbocharger and suitable supporting hardware.

Advertised Performance: Up to 446 HP

Stage 1 is designed to improve acceleration and throttle response without requiring the extensive hardware upgrades associated with higher tuning stages.

Stage 1 Highlights:

• Designed for compatible factory-turbocharger configurations.

• Supports applicable 91- and 93-octane calibrations.

• Optional TrueFlex upgrades are available for compatible vehicles.

• Compatible intake upgrades can support airflow and turbocharger sound.

• Includes supported adjustable throttle response features.

• Available through the applicable IE tuning package.

Stage 2 ECU Tune

The IE Stage 2 calibration is designed to increase the performance potential of the factory turbocharger when paired with the required supporting modifications.

Required Stage 2 Hardware:

• Compatible performance air intake.

• Upgraded downpipe.

• Upgraded intercooler.

A compatible cat-back exhaust can complement the setup and enhance exhaust sound. Stage 2 also supports the available exhaust-related features according to the selected software package.

Confirm the required hardware and calibration availability for your exact vehicle before purchasing.

Stage 3 Turbo ECU Tune

Stage 3 is designed for compatible upgraded turbocharger configurations, including supported TTE810 and Pure750 turbocharger options.

Advertised Performance: Up to 613 HP

This stage requires a compatible larger turbocharger and supporting intake, intercooler, downpipe, and turbo inlet pipe upgrades, along with the appropriate IE Stage 3 Map Pack.

Stage 3 Hardware Requirements:

• Compatible TTE810 or Pure750 turbocharger.

• Performance air intake.

• Upgraded intercooler.

• Compatible downpipe.

• Compatible turbo inlet pipe.

• IE Stage 3 Map Pack and the required tuning package.

Stage 3 requires the applicable IE APEX package, according to the supplied product information.

Stage 3 Plus ECU Tune

Stage 3 Plus is designed to extend the performance potential of compatible Stage 3 turbocharger builds through additional sensor and fuel-system upgrades.

Advertised Performance: Up to 739 HP

The Stage 3 Plus configuration requires additional supporting hardware, including upgraded 4-bar MAP sensors, a high-pressure fuel pump upgrade, and larger Audi 4.0T RS injectors.

Stage 3 Plus Hardware Requirements:

• Compatible TTE810 or Pure750 turbocharger configuration.

• Supporting Stage 3 intake and turbocharger hardware.

• 4-bar MAP sensors.

• High-pressure fuel pump upgrade.

• Larger 4.0T RS injectors, identified in the supplied information as Audi part number 06M906036AD.

• E70 ethanol fuel and a compatible IE TrueFlex Kit for the stated maximum-output configuration.

• IE Stage 3 Map Pack and the required APEX package.

Actual output depends on fuel quality, hardware configuration, calibration, and vehicle condition. Confirm all part numbers and requirements with Integrated Engineering before ordering.

TrueFlex Ethanol Tuning

IE TrueFlex is designed to adjust supported engine calibration parameters according to the ethanol content detected in the fuel system. With compatible TrueFlex hardware and software, drivers can use supported gasoline, E85, and intermediate ethanol blends without manually reflashing the ECU for every change in fuel composition.

TrueFlex can adjust supported boost, ignition timing, and fueling parameters to suit the detected ethanol content.

Important: TrueFlex requires compatible hardware, software, and vehicle support. The highest advertised Stage 3 Plus output requires the specified fuel-system upgrades and E70 ethanol configuration described by the manufacturer. Do not assume E85 compatibility on a vehicle without the required supporting equipment.

Adjustable Throttle Response

The IE tuning suite includes up to 15 customizable throttle-response settings, allowing drivers to tailor accelerator-pedal response to their preferences.

Settings range from a calmer, more progressive response for everyday driving to a sharper response for performance-oriented use. Supported adjustments can be made through the IE app or compatible integrations without adding separate throttle-control hardware.

Exhaust Crackle & Flap Control

The optional Exhaust Crackle feature adds a motorsport-inspired sound during supported deceleration and gear-change conditions. Compatible exhaust flap controls allow drivers to adjust exhaust character where supported by the vehicle and software package.

Feature availability depends on the selected tuning package, vehicle configuration, and software support. Confirm whether each function is included with the selected product.

Anti-Lag & Rolling Anti-Lag

IE Anti-Lag is designed to build boost before launch, while Rolling Anti-Lag is intended to support boost response during rolling acceleration.

Supported launch RPM adjustments may be available through the IE app, compatible cruise-control controls, or CarPlay integrations.

These functions can increase thermal and mechanical stress on the engine, turbocharger, transmission, and exhaust system. Use them only with compatible hardware and according to the manufacturer's instructions.

AutoProtect & Software Development

IE's AutoProtect strategy is designed to monitor critical engine operating conditions and reduce power when necessary. The calibration is developed to balance performance with supported engine protection strategies.

Actual protection functions and operating limits depend on the selected calibration, installed hardware, and vehicle software. ECU tuning cannot eliminate the mechanical risks associated with increased power output.
