Overview

The 034Motorsport TCU Software is a transmission control unit upgrade designed for B9/B9.5 Audi S4, S5, and SQ5 models equipped with the AL552 8-Speed ZF8 transmission. This software can be flashed directly through your vehicle’s OBD-II port and offers Stage 1, Stage 2, and Stage 3 calibrations. It optimizes transmission operation for performance ECU tuning, enhancing acceleration without compromising comfort or reliability.

The software allows for end-user flashing, enabling tune updates, revisions, and stock flashes. For late 2022+ vehicles with factory-locked transmissions, an optional BLU Harness is available to unlock the TCU for flashing via 034SPI.

Built for enthusiasts. Every order is backed by our 30 day return window on eligible items.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
