iE TRANSMISSION PROGRAMMING Audi B9 A4 / A5 / Q5 2.0T

iE's Transmission Control Unit (TCU) for Audi turbocharged B9 A4, A5 and Q5 2.0T models brings more power, faster shifts, adjustable launch control and several other transmission performance-enhancing features. Combined with compatible ECU programming, acceleration is significantly improved, transforming the tuned turbo engine into a true all-round performance car.

LEADING FEATURES

Lightning-fast shifts – improves acceleration and 0-100 km/h times
Full power from ECU programming – removes power-limiting torque limiters
Adjustable launch control – fine-tune the launch to suit your setup
Activating the gear display – the instrument cluster always shows the gear in use in Drive and Sport modes
Full torque in AMAX shifts – torque limit programming removed
Compatible with iE Stage 1 and Stage 2 ECU programming

PERFORMANCE IN PERFECT BALANCE

Unlock the full potential of your iE B9 2.0T Stage 1 and Stage 2 engine programming with a compatible Transmission Control Unit (TCU). Without it, power gains and performance features will be limited, leaving acceleration and power untapped.

iE TCU programming significantly improves shift speeds, removes torque limiters, increases line pressure to prevent transmission slippage, and introduces user-adjustable launch control. The end result is significantly better power output, stronger pull, sharper shifts, and significantly better overall acceleration.

ADJUSTABLE LAUNCH CONTROL

Experience powerful launches with iE's transmission programming, which includes adjustable launch control. Designed for optimal performance, the system offers three different launch settings:

Street , Aggressive and Race

Each setting increases the starting RPM and allows you to tailor the output to your vehicle and tire configuration for the best traction and power output. Each setting has two RPM and AMAX options, controlled by the accelerator pedal:

• Press the accelerator pedal 100% without activating the kickdown switch → start at the selected minimum speed without AMAX

• Press the accelerator pedal all the way down and activate kickdown → start +400 rpm higher and AMAX in all gears, maximum and most aggressive start and acceleration strategy

Launch settings

Note: AMAX is an advanced shifting strategy that significantly improves acceleration by maintaining power on both transmission clutches simultaneously during gear changes. This provides a clear advantage, especially in competitive acceleration driving.

DRIVEABILITY IMPROVEMENTS

Factory-programmed transmission mapping often falls short of the performance-seeking requirements of drivers. iE TCU programming addresses these shortcomings by completely re-engineering the transmission mapping for enthusiast use.

In addition to driveability improvements, TCU programming brings the following features:

• Shorter delay in starting

• Gear display active in the instrument cluster in Drive and Sport modes

• Removes factory default torque cut on AMAX shifts

• Adds protection by automatically reducing engine power if the gearbox temperature gets too high

VEHICLE COMPATIBILITY

Important:
Compatible with 2017-2020 DL382 DSG Gen 1 transmissions only. TCU programming is not compatible with 2021+ Gen 2 TCU versions. In some rare cases, 2019-2020 model year vehicles may have an unsupported Gen 2 version.
