034Motorsport 2.5TFSI EVO Performance Software, 8V/8S Audi RS3/TTRS

Overview

034Motorsport Dynamic+ Performance Software for the Audi 8V RS3 and 8S TT-RS equipped with the EA855 2.5TFSI EVO engine. 034Motorsport 2.5TFSI EVO tunes are flashed directly through the factory OBD-II port using the 034Motorsport Dynamic+ End User Flashing Kit, and offer dramatic increases in horsepower and torque throughout the powerband. The 034Motorsport Dynamic+ End User Flashing Kit allows customers to install their 034Motorsport Dynamic+ Performance Software themselves. In addition, End User Flashing allows Dynamic+ Performance Software customers to receive and install software updates and revisions, flash back to stock, or upgrade to the next stage of performance software for their vehicle.

Details

Unlock the full potential of your 8V.5 Audi RS3 or 8S Audi TT RS with 034Motorsport Dynamic+ Performance Software for the EA855 EVO 2.5 TFSI engine. Developed entirely in-house and validated on both development and enthusiast-owned vehicles, Dynamic+ ECU Tuning delivers significant gains in horsepower, torque, throttle response, and overall drivability while maintaining OEM-level reliability and smooth power delivery. Flashed directly through the factory OBD-II port, the calibration is engineered to provide consistent performance on the street, drag strip, or road course without sacrificing everyday usability.

ECU Features

Power & Performance

Dynamic+ ECU Tuning delivers dyno-proven horsepower and torque gains throughout the powerband with refined boost, ignition, and throttle mapping for stronger acceleration and improved drivability. Stage 1 requires no hardware upgrades, while Stage 2 is optimized for common bolt-on modifications. Raised rev limits of up to 7,400 RPM provide a broader usable powerband, and calibrations are available for 91 octane, 93 octane, and E85 fuel.

Engine Protection

Rather than simply increasing boost pressure, Dynamic+ focuses on delivering smooth, predictable power while maintaining safe operation of the EA855 EVO powertrain. Refined throttle mapping and transient boost control improve vehicle balance, throttle precision, and overall drivability under both street and track conditions.

Fuel System Optimization

Dynamic+ supports 91 octane, 93 octane, and E85 calibrations. The E85 calibration is a dedicated ethanol tune and is not a flex-fuel calibration. Stage 2 E85 requires the 034Motorsport Bosch 980cc MPI Injector Kit, while Stage 2 MPI also includes 91 and 93 octane files for owners traveling where E85 is unavailable. Running MPI does not increase performance on pump gas compared to the factory injectors.

OEM+ Features

Dynamic+ includes several enhancements that improve both performance and everyday drivability:

• Refined throttle mapping for improved response and pedal precision
• Raised rev limit up to 7,400 RPM (calibration dependent)
• Speed limiter removed
• Wastegate rattle reduction during idle and light-load driving
• Crackle Overrun enabled in Dynamic Mode
• Optional no-crackle calibration available upon request
• Flashing through the factory OBD-II port

Fuel & Hardware Requirements

• Stage 1: No additional hardware required on pump fuel
• Stage 1 E85: Requires compatible TCU software to support the increased torque
• Stage 2: Requires a high-flow downpipe, upgraded intercooler, and performance intake
• Stage 2 E85: Requires the 034Motorsport Bosch 980cc MPI Injector Kit
• Available in 91 octane, 93 octane, and E85 calibrations
• E85 calibration is not a flex-fuel tune and requires pump E85 only

Compatibility Notes

• Fits 8V.5 Audi RS3
• Fits 8S Audi TT RS
• EA855 EVO 2.5 TFSI engine
• Supports Stage 1, Stage 2, and Stage 2 MPI ECU calibrations
• Flashes directly through the factory OBD-II port

Important Notes

• The E85 calibration is a dedicated ethanol file and should not be used with gasoline blends or race fuel mixtures.
• Stage 2 E85 requires the 034Motorsport Bosch 980cc MPI Injector Kit.
• Stage 1 E85 applications require compatible TCU software to safely manage the additional engine torque.
• Stage 2 calibration requires a high-flow downpipe, upgraded intercooler, and performance intake.
• Stage 2 Crackle Overrun is enabled in Dynamic Mode, with a no-crackle calibration available upon request.
• MPI-equipped vehicles can flash 91 octane or 93 octane files when E85 is unavailable, but MPI does not increase pump-gas power compared to the factory injector configuration.
