EFFORTLESS E85
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.

ANTI-LAG LAUNCH
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.

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.

STAGE 1 & 2 PLUS
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.

BRAKE BOOST
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.

EXHAUST OVERRUN
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.

AUTOPROTECT
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.

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 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.

Required Hardware:

• TCU Tune

Optional Hardware:

• AIR INTAKE
• TURBO INLET PIPE
• AIR TO AIR INTERCOOLER
• CATBACK EXHAUST
• HPFP UPGRADE

Not Compatible:

• DOWNPIPES

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.
