ECU STAGES

HIGH PERFORMANCE ENGINE PROGRAMMING

IE 2.9T STAGE 1

IE Stage 1 ECU calibration is a simple flash-only upgrade that delivers instant performance with up to 542HP and 558ft-lbs of torque! The larger powerband, 7000RPM rev limit, and increased boost pressures produce exceptionally faster 0-60 times and acceleration in any scenario. This advanced calibration can be installed in an entirely stock car or will adapt to take advantage of intake and intercooler upgrades.

See performance tab for full performance results & dyno reports

IE 2.9T STAGE 1 PLUS

IE Stage 1 Plus delivers the most power possible from E85 fuel with an upgraded HPFP (High Pressure Fuel Pump). By increasing the fuel pump's ability to supply additional ethanol demands, our Stage 1 Plus tune produces an even more significant surge in power with a massive 604 horsepower and 660ft-lbs of torque! This ECU calibration pushes your Audi RS5/RS4 into a higher vehicle class of performance with an intense pull. Requires HPFP upgraded internals with 11.7mm pin size

Stage 1 Plus is included at no additional cost.

IE 2.9T STAGE 2 / STAGE 2 PLUS

IE Stage 2 and Stage 2 Plus ECU tunes are calibrated for aftermarket downpipes to deliver a louder exhaust note and include a more aggressive exhaust overrun/crackle feature in dynamic drive mode.

The 2.9T engine includes two already efficient factory downpipes that do not result in power or exhaust restrictions on stock turbocharger ECU tunes. Although this platform does not provide additional power gains on Stage 2 tunes, IE files will provide the necessary ECU calibrations to support aftermarket downpipes for users looking for a more aggressive exhaust note.

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. When you install the required matching hardware, follow the instructions on your IE POWERlink app to purchase the tune upgrade, and you will be blowing away the competition in minutes!


HARDWARE GUIDE

While no hardware upgrades are required for Stage 1, upgrading the intake, turbo inlet, and intercooler will provide increased airflow, lower intake air temps, and quicker heatsoak recovery for an overall more efficient and faster vehicle.

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.

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.

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.

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.

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.

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.

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.

TCU STAGES

HIGH PERFORMANCE TRANSMISSION TUNING

IE 2.9T STAGE 1 TCU

IE ECU tunes far exceed the torque limitations of the stock RS5/RS4 transmission programming, which triggers the TCU to limit power output. The included IE stage 1 TCU tune raises these torque limits while keeping all transmission driving characteristics otherwise stock.

Stage 1 TCU is included with all ECU tunes at no extra charge.

IE 2.9T STAGE 2 TCU

IE's Stage 2 and 2 Plus TCU tunes are complete performance transmission calibrations 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 RS5 or RS4, delivering faster launches, higher Gs, and further improved acceleration. Stage 2 Plus TCU is for use with Stage 1 & 2 Plus ECU tune.

Stage 2 & 2 Plus TCU is an optional upgrade and sold separately.

STAGE 2 OPTIMIZED SHIFT POINTS

Stage 2 TCU remaps 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 7000 RPM in all gears in manual mode, retaining complete manual control over the shift points.

Important Note: Audi is currently implementing new security patches on the ZF8 transmissions that are being mated to the RS5/RS4 2.9TT engine. These security patches are not specific to any particular model or year of vehicle. These security patches have not been fully cracked by the aftermarket and the cars require additional work for IE's calibrators to flash. If your car has this rare combination, you may experience a brief wait period to flash while our calibrators bypass the security patch.

IE Stage 2 + HPFP 2023 RS5 Sportback B9.5, AWE exhaust, Catted Redstar Downpipes, 034 Full Intake System

I love the tune it really wakes up my car but the one thing I’m upset about is that we still don’t have the stage 2 tcu tune for b9.5 RS5s. Without it I can’t experience the tune fully and I actually sometimes get slower 0-60 times and more turbo lag since the ecu and tcu aren’t communicating the same thing. It’s frustrating because I was really lookin forward to everything like the faster shift speeds and aggressive launch mode and stuff like that. I hope you guys can crack the code for that one soon bc as of rn 2020+ models cannot get the full experience of this great tune but I’m still putting 5 stars bc my friend has a 2019 and man when the ecu and tcu is stage 2 it makes a huge difference.

Very Impressive

The increase in overall performance is immediately noticeable. The consistent power through the rev band is very satisfying to say the least. I did extensive research before going with IE, and I’m thrilled with the choice I made. I use IE for all of my performance parts. I also like the ability to have gauges at the ready, and while keeping the POWERlink connected I can check my engine for codes anytime. As said in the title, very impressive!!!

Super happy with tune

I had only done APR in the past. IE Tune and Carbon Fiber Cold air intake is the perfect set up for me. Very happy with the power and torque. Highly recommend.

This is on my 2023 RS5 Sportback.

Great Tune!

If you are on the fence about tuning your car do it! This tune loaded flawlessly and the car runs great. I have had competitors tunes in the past and wasn't to impressed but this one I can truly tell the difference. I currently am on the stage 1 93 octane but next summer will be going to a HPFP and e85.

Thank you IE!!
