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 builds turbo 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.

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 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.

• Recalibrated factory boost gauge displays higher boost
• Neutral/park rev limit raised to 6500 RPM
• Road speed limiters removed
• Brake boost enabled for rolling launches
• Auto-start/stop defaults to off (can be turned back on)
• Includes advanced TrueFlex ethanol (requires hardware)
• Shielded by iE AutoProtect
• More aggressive overrun/crackle in Dynamic mode
• Crackles enabled for free revving in park or neutral
• Includes advanced TrueFlex ethanol (requires hardware)

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.

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.

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 505 horsepower and 650 ft-lbs of torque! Requires iE HPFP upgrade.

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 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.

Required:

• STAGE 1 TCU TUNE
• DOWNPIPE

Optional:

• AIR INTAKE
• TURBO INLET PIPE
• CHARGE PIPES
• INTERCOOLER
• RACE INTERCOOLER
• CATBACK EXHAUST
• HPFP UPGRADE

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.

TCU Software

PERFORMANCE MATCHED
iE's Performance Transmission Tune for your Audi B9/B9.5 S4, S5, or SQ5 3.0T delivers unmatched acceleration and power delivery. This cutting-edge TCU tune transforms your turbocharged Audi into a complete and fully realized powerhouse. Experience seamless integration with lightning fast shift speeds, enhanced torque maps, eliminated clutch slip, and hard hitting launch control -all designed to work in perfect harmony with your iE engine tune. Unlock the full potential of your Audi with the ultimate TCU tuning suite.

LAUNCH CONTROL
The iE 3.0T TCU Tune includes a reworked launch control to deliver chest pounding launches from a stop. 2021+ (B9.5) years include an optimized launch control setting, resulting in dramticially improved 0-60 times in any scenario. 2017-2020 (B9) years include user-adjustable settings (street, aggressive, or race) to dial in the launch torque for your power and tire combination.

DRIVING ENHANCEMENTS
The factory transmission calibration has many performance shortcomings, leaving much to be desired by enthusiast drivers. iE software engineers have completely reworked the transmission tune computer for performance driving, ensuring the engine and transmission remain in the proper gear without any annoying gear-hunting situations. iE ECU tunes include differences in shift point and throttle mapping between drive and sport modes, allowing for 7th and 8th gears in all modes and eliminating delays when dropping multiple gears, delivering near-instant boost and power on demand.

OPTIMIZED SHIFT RPM
The iE TCU Tune remaps each gear's RPM limits for the fastest possible acceleration. Every gear will shift at the optimal points to pull the car through the powerband as quickly as possible for the fastest conditions on road, track, or drag strip 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 6500 RPM in all gears in manual mode, retaining complete manual control over the shift points.

EASY MOBILE INSTALL
iE's POWERlink Suite Tuning App gives you the freedom to quickly flash your new iE ECU or TCU Tune from your phone. Simply plug your POWERlink into the vehicle's OBD-2 port and follow the app directions, it's that easy!

• Enables launch control in drive, sport, and manual modes
