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.

• 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)

 

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.

• More aggressive overrun/crackle in Dynamic mode
• Crackles enabled for free revving in park or neutral
• Includes advanced TrueFlex ethanol (requires hardware)

 

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.

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.

• Stage 3 for stock fueling
• Stage 3 Plus (4 bar MAPs, HPFP, and injector upgrade)
• Inlcudes TrueFlex ethanol option (requires Stage 3 Plus)
• Stock downpipe files included
• Massive power with minimal boost lag increase
• Neutral/park rev limit raised to 7000 RPM

 

EXHAUST OVERRUN

The stock calibration features a very mild overrun/crackle when you decelerate from higher RPM, but is very hard to hear with factory downpipe/exhaust. Stage 2 & 3 files turn up the aggressiveness of this overrun and enable crackles on free-revving in neutral or park. Not only will your car drive faster, it will sound faster too! Guaranteed to put a smile on your face.

Exhaust Overrun is included on stage 2/3 tunes.

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.

Brake Boost is included on all tune stages.

TCU Tune:

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.

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.

• Increases transmission torque limits
• Inlcuded at no extra cost with all stage 1 & 2 ECU tunes
• A man shifting a car

 

TCU STAGE 2

THE COMPLETE TRANSMISSION PERFORMANCE TUNE

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 S4, S5, or SQ5, delivering faster launches, higher Gs, and further improved acceleration. Stage 2 TCU is for use with either Stage 1 or 2 ECU tune.

• Enables launch control in drive, sport, and manual modes
• Includes user-adjustable launch control settings
• Lightning-fast shift speed
• Optimized shift points for the fastest acceleration
• Enables 6500 RPM limit in all gears in manual
• 7th and 8th gear enabled in sport mode
• Enables downshifting into 1st gear without coming to full stop
• Refined drive for the automotive enthusiast
• Reduces time for double-downshifting gears
• Line pressure increased to protect against trans slip
   

TCU STAGE 3

MATCHING TRANSMISSION TUNE FOR STAGE 3 HYBRID TURBOS
Stage 3 ECU tunes for hybrid turbos deliver massive power gains across the entire powerband and further into the higher RPM range. These performance enhancements require a complete matching transmission calibration. iE Stage 3 TCU Tune is the matching transmission calibration for hybrid turbos with optimized shift points, further increased RPM limits, and new drive-mapping. The stage 3 TCU tune is provided as a free upgrade from Stage 2 TCU when upgrading to Stage 3 ECU tunes.

• Optimized shift points for hybrid turbo upgrades
• Enables 7000 RPM limit in all gears in manual

 

OPTIMIZED SHIFT POINTS

iE Stage 2 and Stage 3 TCU tunes remap 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 6500 RPM in all gears in manual mode, retaining complete manual control over the shift points.

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.
