ECU Tune 3.0T Performance Tune

The Integrated Engineering IESOVJ31 ECU tune is a performance software upgrade for Audi 3.0T supercharged vehicles, including B8/B8.5 S4, S5, C7 A6, A7, Q5, and SQ5 models. This tune is designed to deliver substantial increases in horsepower and torque, with maximum potential reaching up to 548 horsepower and 525 ft-lbs of torque when utilizing the Apex tune with E40 ethanol and the 80mm throttle body upgrade. The tune offers multiple tiers: Core, Pro, and Apex, each with increasing levels of features and performance. Users can select from various fuel options, including 91, 93, E30, E40, 100, and 104 octane race fuels, and optimize for different hardware configurations such as stock pulleys, single pulley, dual pulley, air intake, upgraded heat exchanger, downpipes, cat-back exhaust, upgraded HPFP, and an 80mm throttle body. Standard features across all tiers include POWERlink Mobile for smartphone control, a 7200 RPM limit (requiring a DSG transmission tune), fuel drain capability, speed limiter removal, and free lifetime support. Advanced features like exhaust crackles, manual fan control, 2-step launch control, and a higher 7350 RPM limit are available in the Pro and Apex tiers. Important compatibility notes include: 2016-2018 A6 & A7 models with the CREC engine variant and some late model ROW (non-US) S4/S5 models with the CREC variant are NOT compatible with this tune. CREC engines can be identified by their 4-bolt supercharger pulley, as opposed to a press-fit style. Additionally, dual pulley tunes require a DSG transmission tune or clutch upgrade, and the HPFP upgrade is required for Dual Pulley E40 fuel. Users must ensure their vehicle's ECU is compatible before purchasing.
