ECU STAGES

STAGE 1
UP TO 542HP & 558FT-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 7000 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)
• Includes Stage 1+ for use with iE HPFP upgrade

STAGE 2
FOR THE EXHAUST LOVER

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.

• More aggressive overrun/crackle in Dynamic mode
• Crackles enabled for free revving in park or neutral
• Includes advanced TrueFlex ethanol (requires hardware)
• Includes Stage 2+ for use with iE HPFP upgrade

UPGRADING STAGES
Upgrading from Stage 1 to Stage 2 or beyond is easy! With IE, you only pay the difference in tune cost with no extra fees. After installing any required hardware, launch your IE POWERlink software and enjoy the next power level in minutes!

EASY INSTALL FROM HOME OR AT ONE OF OUR SHOPS

IE's POWERlink Cable and Flash Wizard software gives you the freedom to quickly flash your new IE ECU Tune. Simply plug your POWERlink into the vehicle's OBD-2 port and follow the on-screen directions, it's that easy!

Please note that if you are planning on flashing your car at home, we highly recommend having a proper battery charger on hand. If your vehicle loses power while flashing it, you run the risk of damaging your ECU.

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.

TECHNICAL FEATURES

IE calibration engineers have not only made the engine more powerful, every ECU stage includes extensive adjustments and features to make every bit of the driving experience refined and enjoyable.

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 only enabled in Dynamic drive mode. Exhaust Overrun is included on stage 2 tunes only.

BRAKE BOOST
Brake Boosting is commonly used in roll racing, which allows you to build extra boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" or extra power surge.

Brake Boost is included on all tune stages.

THROTTLE MAPPING
IE engineers have mathematically rescaled the entire mass flow model over 30 maps which corrects the entire throttle input range. This extensive remapping work delivers a linear and predictable throttle pedal with clean and linear boost delivery, which improves drivability in any scenario.

BOOST CONTROL
The stock ECU, boost control programming is a very "close enough" approach, which works fine in low-boost and stock power output. When increasing performance, this slow response is reflected in the torque curve and can feel erratic on long power pulls. IE calibrators have smoothed the power curve by introducing a new boost control mapping strategy with precision boost request targeting, resulting in unmatched power delivery.

VE MODELING
The factory 2.9T engine's MG1 ECU relies on a complicated volumetric efficiency (VE) model to convert boost to engine load and accurately deliver fuel for various conditions. Instead of depending on fuel correction tables to compensate, our calibrators have remodeled the VE mapping for the new boost/load relationship. This extensive work delivers reliable and proper fueling and smooth power delivery you can feel.

EGT OPTIMIZATION
ECU programming uses exhaust gas temp (EGT) readings to make air/fuel corrections and determine the health of the combustion cycle. Countless development hours were spent adjusting boost, air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for every octane file.

Enjoy power gains from different fuel options knowing each was individually optimized to provide reliable engine operation without sacrificing power.
