Advanced Performance Features

Increased 7,200 RPM Limit

Integrated Engineering raises the ECU's RPM limit to 7,200 RPM across the available tuning stages, allowing the supercharged engine to operate through an extended powerband.

According to the manufacturer, the increased operating range can unlock more than 20 additional horsepower in the upper RPM range.

Important: The matching IE Transmission TCU Tune is required to access the increased RPM range. Without it, the factory transmission calibration may shift at approximately 6,300 RPM.

Optimized Supercharger Cooling

The IE ECU Tune modifies the factory coolant pump calibration to improve charge-air cooling and reduce the effects of heat soak.

The revised cooling strategy includes:

• 50% coolant pump duty when the ignition is switched on.

• Coolant circulation through the charge coolers without requiring the engine to run.

• 100% coolant pump operation during driving or when intake temperatures exceed 20°C.

• Improved cooling recovery between demanding driving sessions.

Brake Boost Functionality

Brake boost functionality is included across the available ECU tuning stages.

This feature allows compatible vehicles to build additional boost while brake pressure and accelerator input are applied simultaneously, providing additional acceleration response when brake pressure is released.

Use this performance feature only in appropriate controlled environments.

E85 Ethanol Calibration

The included E85 calibration is designed to take advantage of ethanol fuel's cooling properties and high resistance to engine knock.

Integrated Engineering incorporates safeguards that allow the calibration to adapt to variations in ethanol concentration, with the manufacturer describing support for ethanol content as low as approximately E60.

The available fuel maps allow drivers to select the appropriate calibration for their intended fuel.

Important: Select the correct fuel calibration and follow Integrated Engineering's fuel requirements. The presence of multiple fuel maps does not mean the vehicle automatically switches between gasoline and ethanol calibrations.

Transmission Tuning Compatibility

All available IE ECU tuning stages for the supported C7.5 Audi A6 and A7 are compatible with the matching IE ZF8 AL551 Transmission TCU Tune.

Although optional, the transmission calibration is highly recommended to achieve the advertised performance potential.

The matching TCU tune provides enhancements to:

• Transmission shift speed.

• Transmission torque-limit calibration.

• Transmission line pressure.

• Launch control functionality.

• Shift-point optimization.

• Access to the ECU tune's increased 7,200 RPM operating range.

Without the matching TCU tune, the transmission may shift at approximately 6,300 RPM, preventing the engine from fully utilizing the extended powerband.
