Ethanol is rocket fuel for your daily driver. Our TrueFlex flex fuel conversion kit upgrades the factory engine computer to read and instantly adapt to any ethanol blend, unleashing huge power.
Gain the boosted advantage with iE’s advanced anti-lag launch and rolling launch control standard on all stages. This custom-coded strategy build boost before takeoff, delivering an aggressive launch that shaves down acceleration times. Fine-tune your launch with instant launch-RPM switching and adjust your launch point in real time to match tires, surface, and conditions without reflashing. For roll racing, rolling anti-lag holds a set RPM and speed while building boost to unleash instant power and gain the upper hand when it counts.

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.
The 2.9T engine includes two larger and efficient factory downpipes that do not result in power or exhaust restrictions on stock turbocharger. Although this platform does not provide additional power gains on Stage 2 tunes, this is ideal for users seeking a more aggressive exhaust note and includes an enhanced exhaust overrun/crackle feature in dynamic drive mode.
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!
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.
Ethanol options available on all stages
Stage 1 & 2 Plus tunes require an upgraded High-Pressure Fuel Pump (HPFP) to unleash the maximum power potential from E85 fuel. This enhanced HPFP can deliver a higher fuel demand, resulting in a remarkable 604 horsepower and 660 ft-lbs of torque! Requires iE HPFP upgrade.
HPFP Plus tunes are included with stage 1 & 2
Commonly used in roll racing, Brake Boosting allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra surge of power.
Brake Boost is included on all tune stages.
Stage 2 files turn up the volume on exhaust overrun crackles for an exciting exhaust sound on engine decel and when free-revving in neutral or park. This feature is enabled in Dynamic drive mode.
Exhaust Overrun is included on stage 2 tunes.
Even with the best tuning, unreliable fuel and mechanical failures still pose a risk to any engine. iE AutoProtect is your last line of defense against engine damage. If trouble pops up, AutoProtect lowers boost and power to keep your engine safe against damage. When conditions return to normal, power automatically restores. Our unique error code is triggered so we can help pinpoint the problem. LEARN MORE

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 2.9TT engine. While Stage 1 doesn't require any hardware upgrades, adding our intake, turbo inlet, and air to air 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.

Important Notice:2021+ models are equipped with advanced security locks that prevent Stage 2 & 3 Transmission tuning. iE calibrators are currently working on bypassing the security to offer TCU tuning for all model years. In the meantime, iE TCU Stage 1 is fully compatible and will allow full power output from the ECU tune.
iE ECU tunes far exceed the torque limitations of the stock B9 2.9TT 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.
Stage 2 TCU tune is a complete performance transmission calibration that delivers lightening fast shifts, optimized shift points, multiple launch-control modes, enthusiast drive mapping, and more! Pairing this TCU calibration with an iE Stage 1 or Stage 2 ECU tune will significantly transform every aspect of your RS5, or RS4, delivering faster launches, higher Gs, and further improved acceleration.
Stage 2 TCU is for use with either Stage 1 or 2 ECU tune.
iE Stage 2 TCU remaps each gear's RPM limits for the fastest possible acceleration by shifting at the optimal points to keep the engine in peak torque/power output. This strategy pulls the car through the powerband as quickly as possible with incredible improvements in acceleration and G's. These optimized shift points occur when in drive mode, sport mode, and AMAX. The transmission limit remains 7000 RPM in all gears in manual mode, retaining complete manual control over the shift points.
