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 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 B9 3.0T into a track-ready machine while maintaining everyday comfort during your daily drives.

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.

Ethanol options available on all stages

Silver Audi

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 tunes.

Grey Audi

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.

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.

HPFP Plus tunes are included with stage 1 & 2

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.

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

TCU STAGE 2

THE COMPLETE TRANSMISSION PERFORMANCE TUNE

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 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.

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

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. This 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
Grey Audi

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.

2020 SQ5

All I am say is this tune is amazing. Makes my SQ feel totally different from stock. The power is there right away and also with their E85 tune it gives you another choice for even more fun. Thank to I.E new wireless obd installing my tine couldn’t be any easier. Right from my phone I can update the software and change maps to whatever fuel I’m using. With a simple click and done. No more needing that laptop. But overall I very much highly recommend this and I can’t wait to go stage 3!!!

Loving the ECU Tune so far!

Coming from the FA20 Subaru platform and the Cobb AP, I've found that iE's Powerlink is sooo much more convenient since you can use your phone instead of having to download it to your computer and then add it to the AP. Very happy with this product so far!

2024 S5 STAGE 2 ON E85

Stage 2 with HPFP on E85 is absolutely awesome! I love it and I haven't had issues with it. Nice burbles on Sport mode with aftermarket downpipe. Nothing too annoying to be driving with. On Dynamic mode it sounds stock, almost like nothing is there. The tune shut off the auto start/stop feature which is now a blessing. I hated that thing! Now just waiting for I.E. to put out their Stake 2 TCU. Definitely worth it!

Stage 1 S4 B9

Took awhile to add the tune to the car because after the 1st attempt my battery died suddenly and was not able to start and stop the engine after flashing.. After replacing the battery, all went very smooth. Extremely happy with this tune! Thank you IE for your support!
