Integrated Engineering IE Audi B9 3.0T ECU Tune with TCU Stage 1 (S4, S5 & SQ5)
Take control of your Audi S4, S5, or SQ5 by unlocking thrilling power and acceleration from your phone! Our cutting-edge engine and transmission tunes transform your car through the innovative POWERlink Bluetooth dongle that plugs into your vehicle's OBD II port. Our responsive mobile app links the dongle to your Apple or Android phone, giving you the power to tune your car, change octanes, upgrade stages, perform diagnostics, monitor live gauge data, and more —all from the palm of your hand!
TCU STAGE 1 - INCLUDED WITH STAGE 1 & 2 ENGINE TUNE
iE ECU tunes far exceed the torque limitations of the stock B9 3.0T transmission programming, which triggers the transmission computer (TCU) to limit power output. The included stage 1 TCU tune raises these torque limits while keeping all transmission driving characteristics otherwise stock.
Important Notice: 2021-2024 (B9.5) model years have limited support. Some transmissions are equipped with advanced security locks and cannot be unlocked for tuning. Before purchasing a Stage 2 or 3 TCU tune for these model years, please follow our easy step-by-step Audi B9.5 TCU Unlock Guide using your iE POWERlink Suite App.
Apple & Android phones supported
EFFORTLESS E85
Ethanol is rocket fuel for your daily driver. Our TrueFlex flex fuel conversion kit upgrades the factory engine computer in your B9/B9.5 3.0T to read and instantly adapt to any Ethanol blend, unleashing huge power.
STAGE 1
UP TO 505HP & 585FT-LBS TORQUE
iE Stage 1 ECU calibration is a simple flash-only upgrade that delivers instant excitement, providing a broader powerband, a higher rev limit, and increased boost pressures that result in significantly faster 0-60 times and improved acceleration. This advanced calibration can be installed on a completely stock car, and it will adapt to take full advantage of intake and intercooler upgrades.
STAGE 2
FOR THE EXHAUST LOVER
The B9 3.0T engine comes equipped with a large and efficient factory downpipe, which does not impede power or exhaust flow with the stock turbo. While this platform doesn't yield additional power gains on Stage 2 tunes, Stage 2 provides the necessary ECU calibrations to support aftermarket downpipes. This is ideal for users seeking a more aggressive exhaust note and includes an enhanced exhaust overrun/crackle feature in dynamic drive mode.
STAGE 3
UP TO 739HP & 710FT-LBS TORQUE
For the serious horsepower enthusiast, iE's world-record-holding tunes are purpose-built for use with bolt-in TTE810 or Pure750 hybrid turbo upgrades and compatible hardware. Unlock supercar-level power and torque with remarkable transient response, minimal turbo lag, and an exhilarating pull all the way to the redline. This new power curve completely transforms your 2017-2024 B9 3.0T into a track-ready machine while maintaining everyday comfort during your daily drives.
Reliability Testing
IE's fully proven software brings track-ready ECU programming to your turbocharged 3.0L V6 engine while retaining factory comfort and reliability. IE's own tuning technology suite is used to completely reverse-engineer the factory ECU mapping, allowing our software engineers access to realign all safety protocols and sensors for the new performance calibration. Every tune parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify tune operations in any condition. Confidently drive from LA to Pikes Peak with power that will keep you smiling every mile!
Upgrading from Stage 1 to Stage 2 or beyond is simple with iE! You only need to pay the price difference between the tunes with no additional fees. Once you've installed the necessary matching hardware, just follow the instructions on your POWERlink app to purchase the tune upgrade, and you'll be outperforming the competition in minutes!
ADDITIONAL TUNE FEATURES
ETHANOL FUEL
Ethanol fuels are included and unlock the most performance potential from our ECU tunes. Ethanol contains tons of oxygen, burns cooler, and has a high resistance to knock. This provides more horsepower and torque than running conventional gasoline and is much less expensive than race gas.
HARDWARE GUIDE
Unlock the full potential of your ECU tune with our comprehensive range of iE hardware upgrades. Each tune stage is designed to work seamlessly with optional or required hardware, maximizing the enjoyment of your Audi 3.0T engine. While Stage 1 doesn't require any hardware upgrades, adding our intake, turbo inlet, and intercooler will result in increased airflow, lower intake air temperatures, and quicker heatsoak recovery, leading to a more efficient and faster vehicle overall.

TUNE UPDATES
Your tune purchase entitles you to free updates to any tune revisions, new octanes, standard features, or software updates. In the event the original vehicle manufacturer issues an ECU update, this will also be included to you through iE at no additional charge.
POWERLINK VINS
Have multiple cars in the family or friends that are also ready for an iE Tune? Your POWERlink Flash Tool can be used on up to 5 different vehicle VINs. Tunes sold separately.
TUNE REGISTRATION
Once a tune purchase is applied to your vehicle's ECU, the tune is permanently registered to the vehicle and non-transferable to other vehicles. Tunes can be transferred to a second party in the event of vehicle transfer of ownership only.
REQUIRES V4 IE POWERLINK
The Audi MG1 uses new and updated flashing protocols to read and write the ECU and TCU information. Older V3 POWERlinks do not include the required internal hardware need to flash the B9 3.0T calibrations. If you are purchasing this tune with an existing POWERLINK, please be sure your serial number on the back begins with V4.
