Overview

The 034Motorsport Performance Software is an ECU tune designed for 8V Audi S3, 8S Audi TTS, and MkVII Volkswagen Golf R models equipped with the EA888 Gen 3 2.0T engine and IS38 turbocharger. It is flashed directly through the vehicle's OBD-II port, safely increasing power output, acceleration, and throttle response without sacrificing driveability or reliability. The software was developed and refined in-house by 034Motorsport.

This performance software is available in Stage 1 and Stage 2 calibrations, with options for 91 or 93 octane fuel. Stage 1 requires no hardware modifications, while Stage 2 is engineered for use with a high-flow downpipe upgrade and performance air intake. Both stages offer increased horsepower and torque, a raised RPM limit to 7,100 RPM, and a removed speed limiter. Stage 2 also features crackle overrun in Sport Mode.
Show original supplier description
The 034Motorsport 2.0T Gen 3 Performance Software is a proprietary calibration designed for the EA888 Gen 3 2.0T engine equipped with the IS38 turbocharger, specifically for the 8V Audi S3, 8S Audi TTS, and MkVII Volkswagen Golf R. This software directly interfaces with your vehicle's ECU via the OBD-II port, safely and effectively increasing power output. It delivers a noticeable improvement in acceleration and throttle response, all while maintaining driveability and reliability. The calibrations were developed in-house and refined on multiple enthusiast-owned vehicles. 034Motorsport offers various stages and octane options. Stage 1 software requires no hardware modifications and offers gains up to 87 HP and 119 lb-ft of torque over stock (with 93 octane). Stage 2 software is engineered to further enhance performance when paired with a high-flow downpipe and performance air intake, providing gains of up to 102 HP and 132 lb-ft of torque (with 93 octane). Key features across the stages include increased horsepower and torque throughout the powerband, refined throttle mapping for enhanced response and precision, a raised RPM limit for a broader powerband, and removal of the speed limiter. Stage 2 software also includes an optional crackle overrun feature in Sport Mode for an enhanced exhaust note during deceleration. Additionally, 034Motorsport provides a CARB-exempt Stage 1 file for on-road use in emissions-controlled environments, covered under Executive Orders D-850-1 & D-850-3. The 034SPI Mobile Flashing Application is also available, allowing users to flash their car, change fuel maps, configure data displays, and utilize diagnostic tools from their iOS or Android device.
