B9/B9.5 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.

B9/B9.5 2.9T STAGE 2

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.

STAGE 1 PLUSÂ

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.

Performance Gains

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

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.

Throttle MappingÂ

The new generation Audi MG1 ECU uses a complicated mass flow model to calculate boost control. Typical ECU tunes simply raise the wastegate pressure, however, since the maps that control wastegate position (boost) are not controlled by throttle input resulting in limited throttle predictability. To avoid delivering full-boost at half throttle input, IE engineers have taken the care to rescale the entire mass flow model mathematically over 30 maps which correct the entire range of throttle input. This delivers a linear and predictable throttle pedal which improves drivability in every situation on the street or track.

Boost Control

The stock ECU boost control is delivered in a very â€œclose enoughâ€ and erratic boost curve. This slow response is reflected in the factory torque curve and can be felt on long power pulls when utilizing the entire powerband. To smooth out this torque curve, IE calibrators re-tuned the boost control mapping to be much faster achieving precision boost request targeting that results in unmatched power delivery.

VE ModellingÂ

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

Exhaust Gas Temperature (EGT) is the measurement of fuel mixtures exiting the exhaust and is used to determine the health of the fuel/air mixture entering the engine. IE engineers have spent countless hours adjusting boost air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for ultimate engine safety without sacrificing power on all octanes. Since Ethanol burns cooler than gasoline, the extra fuel left over in the cylinders acts as coolant further reducing combustion temperatures and allows for a leaner air to fuel ratio without dangerous EGT levels. All IE files contain safety measures and complete knock control to keep the engine producing it's potential within verified and safety-first operation.

Upgrading Stages

Upgrading from Stage 1 to Stage 2 or Stage 3 is easy! With IE, you only pay the difference in tune cost with no extra fees. When you install the required matching hardware, simply follow the link on your IE POWERlink software to purchase the tune upgrade and you will be enjoying the next level of power in minutes!

Installation

IE'sÂ POWERlink CableÂ andÂ Flash WizardÂ 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!
