IE Stage 2 ECU Tune

IE Stage 2 performance software is a complete engine calibration for full bolt-on stock turbo builds running an aftermarket racing downpipe and catalyst. The unique B9 EA839 engines are equipped with a smaller factory turbo and large stock downpipe with incredibly minimal exhaust restrictions. Using advanced calibration techniques, IE calibrators can extract full peak power on pump gas and ethanol fuels on Stage 1 and 2 downpipe setups. However, the required hardware upgrades for stage 2 will increase airflow, lower intake air temps, faster IAT recovery, and produce an overall more efficient and faster vehicle on the same power.

Ethanol Fuels

E85 & E40 blend ethanol fuels are included with all stages 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.

Full E85

IE calibrators spent many months developing and testing ethanol blends on the B9 3.0T engines in many climates and elevations. Results were consistent that full E85 runs very close to or beyond the limit of the factory direct injection (DI) fuel system in the mid-range but allows for more power up top. IE's E85 calibration keeps mid-range power in check to avoid lean conditions, misfires, and power loss then ramps it up top for amazingly fast and consistent track times in a drag racing scenario. E85 is also great for easy fill-ups at the pump for daily driving without mixing blends.

E40 Blend

E40 is an ethanol mix of E85 with regular pump 91/93 fuel creating a lower ethanol content fuel. E40 offers the optimal ethanol content for the factory DI fuel system in the mid-range of the power band. The lower content ethanol allows this file to create the maximum power output from 3000RPM-4000RPM, perfect for road course and track racing. E40 will also result in a faster feeling car in most street driving situations.

An ethanol content sensor kit is highly recommended when running ethanol blends.

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.

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 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.

Boost Control

The stock ECU boost control is delivered in a very “close enough” 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.

Throttle Mapping

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.

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 its potential within verified and safety-first operation.

Recalibrated VE

The factory engine calibration shows a significant drop in torque and power around 3000 RPM due to the unique volumetric efficiency (VE) of the stock 3.0T engine. Instead of tuning around this drop in VE or attempting to simply raise the factory torque/load maps to compensate, our calibrators have completely solved and removed this drop from our ECU calibrations entirely.

IE's dyno charts are ported directly from our in-house dyno cells and are not modified or "smoothed" in any way.

Stage 2 Plus HPFP

Stage 2 Plus ECU tune is calibrated to support increased fuel delivery from upgraded HPFP (High-Pressure Fuel Pump) internals providing additional horsepower and torque through the mid-range of the power band. Acceleration dramatically improves with a 52HP gain in the mid-RPM (peak HP number remains the same) and up to 75ft-lbs of additional torque on E85! Our matching Stage 2+ TCU transmission tune (sold separately) also includes optimized shift points that double down on the intense pull through the middle of the powerband, further increasing acceleration and faster 1/4 mile times.

Stage 2+ tunes are included at no additional cost
Requires HPFP upgraded internals with 11.7mm pin size

TCU Patch

IE's calibrators have written a free software patch for the factory transmission control unit (TCU) that raises the torque limits of the AL552 ZF8 automatic transmission to allowing the power gains from IE Tunes. This patch fully realizes all available performance from the IE ECU Stages while keeping all transmission driving characteristics otherwise stock. This TCU patch is a simple installation using the POWERlink cable and is included with all B9 S4 & S5 ECU calibrations at no extra charge.

Easy At-Home Tune Install

Required to flash your new tune, IE's DIY Flash Tool allows you to quickly upload your tune from your own garage or driveway. This OBD plug-in device is easy to use with a Windows powered laptop and WiFi connection. Your new tool also includes the abilities to switch between multiple octane files (available separately), reading and clearing diagnostic codes, upgrading Stages, or flashing back to stock. 

Upgrading Tunes

Already have an IE Stage 1 tune and IE DIY Flash Tool? Upgrading to Stage 2 or beyond is easy! You only pay the difference in cost between the files with no additional or hidden fees. Once the required supporting hardware is installed, simply plug in your DIY Flash Tool and follow the instructions on your screen to purchase and flash the upgrade file.

Dynometer Optimized

After completely reverse engineering the factory ECU, our engineers use our in-house Dynapack DP42 dynamometer to perform repeated runs to test each change that is made to the software and confirm drivability in any situation. This ensures IE performance software delivers massive horsepower and torque increases across the entire powerband. Using our in-house dyno and advanced tuning tools, IE engineers have fully optimized every aspect of the factory ECU mapping on many different vehicles. This produces a tune that retains all factory like driving and safety protocols when needed, and an intense surge of power when you want it.

Removed Speed Limiter

The factory ECU speed limiter has been removed to make sure the increased power and torque can be used to its full potential on straightaways and drag strips.

Improved Throttle Response

To further increase the responsive feel of the car, IE engineers have carefully adjusted the throttle sensitivity. This offers a more connected feeling to your car with plenty of power available right beneath your foot.

Optimized Fueling

All IE tunes have been adjusted to run as economically as possible, dialing in air/fuel ratios to exactly where they need to be. With an IE performance ECU flash, it is common to see increased fuel economy under cruising and part-throttle driving.
