Stage 1 ECU Tune 2.0T TSI Gen 3

The Integrated Engineering IESOVN31 is a performance ECU tune engineered to reprogram your Audi's stock 2.0T TSI Gen 3 engine for maximum power gains on 91 or 93 octane fuel. This tune is designed for the B9 A4/A5 platform and aims to increase horsepower and torque for improved acceleration and mid-range pull. Installation is performed at home using the iE POWERlink V4 mobile flashing device, connecting directly to the OBD2 port from an iPhone or Android, eliminating the need for a laptop or dealer visit. This tune offers several adjustable features directly coded into the ECU, including adjustable throttle, and can be upgraded to Stage 2 or Stage 3 tune suites with the addition of compatible hardware like intakes, intercoolers, and downpipes. The Stage 1 tune is reported to increase output significantly from the factory 252 HP, with potential to reach up to 314 horsepower and 396 ft-lbs of torque on 91/93 octane fuel, and even higher with flex-fuel capabilities when paired with appropriate hardware. The system includes AutoProtect to monitor engine conditions and reduce power if unsafe activity is detected, ensuring reliable daily performance. This tune is compatible with 2017-2020 Audi A4 and A5 models equipped with the 2.0T engine and Quattro (AWD) drivetrains. It is specifically noted that this tune is not compatible with front-wheel-drive (FWD) B9 A4/A5 models. Furthermore, vehicles from 2021 and newer are not covered as they utilize the updated EA888 Gen 4 engine. Some 2019 and 2020 vehicles may have a newer DL382G2 transmission, for which transmission tuning support is not currently available, though engine tuning remains possible.
