Dynamic+ ECU TCU Software Bundle EA837 3.0TFSI CREC AL551 ZF8

The 034Motorsport Dynamic+ Performance ECU and TCU Tuning Bundle is engineered for the Audi C7.5 A6/A7 and D4 A8 featuring the CREC engine code and AL551 ZF8 transmission. This comprehensive tune is flashed directly via the factory OBD-II port, eliminating the need for TCU removal. It delivers substantial gains in horsepower and torque across the entire RPM range, alongside refined throttle mapping for improved response and precision. The software also includes a raised RPM limit to 7,200-7,600 RPM and removes the speed limiter for increased top-end performance. The TCU tune specifically optimizes the AL551 8-speed ZF8 transmission for enhanced performance and drivability. It features increased shift speeds, optimized shift points in Drive and Sport modes, and an optimized launch control. Compatibility is limited to Simos 16 equipped vehicles. This software will not work on vehicles with a factory locked supercharger and a slip-on supercharger pulley (CAKA Engine Code). Customers with a supercharger pulley attached with 4 bolts will find this software compatible, but those with a slip-on pulley will require different software. The 034Motorsport Dynamic+ End User Flashing Kit is required for flashing, and tunes can also be managed via the 034SPI Mobile Flashing application for iOS and Android devices.
