Looking for serious performance gains while keeping factory emissions in check? iE Stage 3 ECU tunes include optional files specifically for use with a stock downpipe. Both Stage 3 and Stage 3 Plus tunes deliver the same impressive power on pump gas (91 and 93 octane) as they do with an aftermarket downpipe. Running E70 ethanol? You’ll see up to 79 HP and 53 ft-lbs less than with an aftermarket downpipe, making it a great balance between power and emissions compliance.

Ethanol-blended fuel provides the maximimum power for iE Stage 3 Plus Hybrid Turbo Tuning Suite. TrueFlex adds our advanced flex-fuel programming to your engine control computer, automatically adjusting engine mapping in real-time to match the exact ethanol blend, eliminating guesswork, and ensuring maximum safe power at all times.

iE Stage 3 and Stage 3 Plus far exceed the factory set transmission torque limit and requires a complete matching transmission control unit (TCU) calibration. IE's matching Stage 3 TCU tune fully harmonizes the complete drivetrain for the hybrid turbo characteristics with optimized shift points, further increased RPM limits, faster shift speed, user-selectable launch control, new drive-mapping, and more.

At every stage of tune development, the results were dyno tested, street verified, pushed on the track, and expanded to a beta testing community. This verification process provides a library of data from various vehicles, fuels, climates, weather conditions, and altitudes, all used to make numerous changes to the files to maximize performance, driving characteristics, and reliability in any situation. In one of these track tests, an early TTE710 (smaller turbo) tune variant set the B9 3.0T world record and became the official first B9 3.0T in the 9s!

Stage 3 horsepower is a serious amount of power for any engine. To keep the stock engine internals safe under these extreme power levels, iE calibration and software engineers employed highly advanced tuning practices and equipment to develop a complete ground-up engine management system within the factory ECU. Extensive mapping rework was performed to support the hybrid turbos and verified in thousands of complete powerband pulls in our dyno cells and countless hours of testing every tune iteration on the street and track. All performance calibrations and safety coding has been rewritten and converted to run with the substantial power gains from the large hybrid turbocharger.

To properly configure the ECU, iE's engineers installed a variety of additional sensors and probes throughout the engine to record critical data that is not available via the factory equipment. This is an expensive and tedious process; however, the information gathered is priceless when calibrating the ECU for the new hardware specifications. The added sensors record cylinder pressures, EGT, exhaust pressure, mass airflow, and more for a high-resolution log of important turbo and engine operating parameters.

The advanced software development strategies provide the confidence to responsibly build a calibration suite for peak power output without relying on risky modeled information or guesses for engine and drivetrain safety. Hundreds of maps have been defined and calibrated from a ground-up approach to create a fully rounded software suite designed to deliver professional motorsport quality performance while improving everyday driving characteristics beyond factory programming. The result is more than adjusted stock tune mapping and delivers a true large turbo engine management system completely realized within the factory ECU.

One of the countless important examples of this advanced programming is the development of the factory wastegate/boost pressure control mapping. The MG1 ECU contains a sophisticated model with many inputs used to ensure proper engine safety adaptations for any operating condition or climate; the compressor efficiency of the larger turbo drastically alters this model. Instead of tuning around these shortcomings with compromises, iE's calibration team expanded the map structure specifically to each hybrid turbo from the ground up, ensuring proper drivability, perfect boost control, safe boost regulation, and guaranteed consistency in all driving conditions.

The vast difference in wastegate flow and response with the larger turbo options compared to the stock turbo provides another extreme example of a situation where the factory mapping has been completely disregarded and replaced with an entirely new strategy. Significant time has been invested in perfecting every input affecting this system resulting in a map that has taken on an entirely different shape matching the characteristics of the hybrid turbo's boost control. This thorough calibration process is the result of many months but delivers unparalleled power delivery and reliable power at any throttle input beyond even the factory feel.
