Choice Gear: Unitronic Launches Performance Software for the 8Y Audi A3 40TFSI

Unitronic is proud to release its Performance ECU & TCU Software for the Audi 8Y A3 40 TFSI equipped with the 2.0L TSI EA888 Gen4-B engine and DQ381 transmission.* With testing and validations completed, power output has been increased by up to +91 HP / +103 LB-FT with Unitronic Stage 2 (93octane/98ron) Performance Software for a maximum of 298 HP / 324 LB-FT.

Due to the unique nature of the MG1CS031 ECU found in the 8Y A3, unlock operations will need to be performed at the Unitronic HQ. Thanks to extensive experience with the latest Bosch MG1 controllers, mail-in ECU Unlocks are typically completed on the SAME-DAY they are received. Depending on the shipping methods you choose at checkout, in some cases you can have your ECU back in your hands within as little as 48-hours.** Click HERE to learn more.

Once the ECU is unlocked, users can tune their vehicles directly through the OBD-2 port within minutes, from the comfort of their own home or garage with UniCONNECT+.*

Transformative Power Gains

Thanks to extensive development and a strict tuning strategy which retains factory safety limiters, Unitronic Software Engineers optimized the MG1CS031 ECU to improve boost control, ignition timing, lambda, camshaft timing and other critical parameters. With supporting hardware upgrades, the result is a significant power increase to 298 HP and 324 LB-FT with Stage 2 93 octane Performance Software.

Refined Drive With Unitronic TCU Software

To support this drastic increase in horsepower and torque, Unitronic strongly recommends its TCU Performance Software which was developed to improve the overall driving experience through calibration adjustments including an increased torque limiter, advanced torque management, adjustable launch control, optimized gear shift points, quicker shifts, and in-dash gear display enablement.

For users with vehicles built after 02/2022 that have locked “401” bootloaders, Unitronic’s TCU Bench Harness can be utilized in order to quickly unlock and tune DQ381.2 transmissions via the UniCONNECT+ / UniPRO+ flashing suite.
